Description

ABANO CON MOTOR PASO A PASO Y SISTEMA DE CONTROL  STEPPER WITH MOTOR STEP BY STEP AND CONTROL SYSTEM
SECTOR TÉCNICO DE LA INVENCIÓN TECHNICAL SECTOR OF THE INVENTION
La presente invención se refiere a un abano, del tipo de los que comprenden un sistema electromecánico ubicado en una carcasa, que se puede anclar en techos y similares, y es capaz de suministrar un movimiento oscilante o de vaivén a un eje de giro del cual pende una vela, o abano propiamente dicho, generando una corriente de aire que proporciona una mayor sensación de confort a las per- sonas que se encuentran en las proximidades del abano. Esta invención presenta notables ventajas e innovaciones frente a los existentes en el mercado con igual o similar función.  The present invention relates to a fan, of the type that comprises an electromechanical system located in a housing, which can be anchored in ceilings and the like, and is capable of supplying an oscillating or reciprocating motion to an axis of rotation of which a candle hangs, or proper fertilizer, generating a current of air that provides a greater sense of comfort to people in the vicinity of the fertilizer. This invention has notable advantages and innovations compared to those existing in the market with the same or similar function.
ESTADO DE LA TÉCNICA STATE OF THE TECHNIQUE
Los ventiladores de techo tienen su origen en Oriente Medio y en sus estadios iniciales se accionaban por impulsión manual, al transmitirles la energía necesaria para su movimiento por medio de un cordón, varilla o similar.  Ceiling fans have their origin in the Middle East and in their initial stages they were operated by manual drive, by transmitting them the energy necessary for their movement by means of a cord, rod or the like.
En los últimos años se han realizado diversas invenciones relacionadas con sistemas mecánicos y eléctricos para la impulsión de estos dispositivos. El estado de la técnica conocido más destacable y próximo al respecto es la solicitud de patente internacional WO 03/072950 A1 ; también se conoce la patente española ES 2014368 A6. Ambos documentos describen sendos abanos accionados por motores eléctricos; no obstante, la invención aquí descrita presenta notables mejoras sobre el estado de la técnica preconizado en el documento WO 03/072950 A1 y otros similares.  In recent years, various inventions related to mechanical and electrical systems have been made to drive these devices. The most outstanding and close known state of the art in this regard is the international patent application WO 03/072950 A1; Spanish patent ES 2014368 A6 is also known. Both documents describe two fans driven by electric motors; nevertheless, the invention described here presents notable improvements on the state of the art recommended in WO 03/072950 A1 and the like.
PROBLEMA A RESOLVER PROBLEM TO SOLVE
Se ha comprobado que los motores que accionan los abanos descritos en el estado de la técnica anterior deben soportar grandes esfuerzos, debido al ele- vado momento de inercia que presentan los elementos móviles del conjunto a la hora de impulsar el movimiento de la vela. Esto hace que dichos motores estén sometidos a altas cargas, por lo que resultan poco silenciosos por las elevadas solicitaciones de par del sistema y, por tanto, incómodos para los usuarios.  It has been found that the motors that drive the fans described in the prior art must withstand great efforts, due to the high moment of inertia that the mobile elements of the assembly present when driving the movement of the sail. This makes said motors subject to high loads, so they are not very quiet due to the high torque requirements of the system and, therefore, inconvenient for users.
Con la invención aquí propuesta se consigue un accionamiento suave del dispositivo, con bajo volumen de ruido del mecanismo de impulsión del abano, necesario por sus condiciones de uso como pueden ser zonas de relax o de des- canso. Además, la cadena cinemática también favorece un bajo nivel de sonoridad, lo que contribuye a generar una atmósfera de confort en las estancias donde se dispongan estos abanos. With the invention proposed here, a smooth actuation of the device is achieved, with low volume of noise from the drive mechanism of the fan, necessary for its conditions of use such as relaxation or disengagement areas. tiring In addition, the kinematic chain also favors a low level of loudness, which contributes to generate an atmosphere of comfort in the rooms where these fans are arranged.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
La invención que se describe es un abano, con un sistema electromecánico, que se puede anclar en techos y similares, capaz de suministrar un movimiento oscilante o de vaivén a un eje de giro, del que cuelga una vela, generando una corriente de aire. Dicho sistema electromecánico comprende:  The invention described is a fan, with an electromechanical system, which can be anchored in ceilings and the like, capable of supplying an oscillating or reciprocating movement to an axis of rotation, from which a candle hangs, generating an air current. Said electromechanical system comprises:
- un motor paso a paso, accionado con la técnica de microstepping (micropasos), que permite mejorar la regulación de la posición de la vela y de su velocidad de giro,  - a stepper motor, driven by the microstepping technique (micropassing), which allows to improve the regulation of the position of the sail and its turning speed,
- una unidad electrónica, integrada por una fuente de alimentación, una placa de potencia ó circuito driver motor, y una placa de control, donde:  - an electronic unit, consisting of a power supply, a power plate or driver motor circuit, and a control board, where:
- la placa de control consta de unas memorias y microprocesadores que son los encargados de gestionar el movimiento del abano, de manera que en las distintas memorias están almacenadas los modos de funcionamiento determinados por una combinación de velocidad angular de la vela y su posición angular, entre las que se mueve la vela del abano, - the control board consists of memories and microprocessors that are responsible for managing the movement of the fan, so that in the different memories the operating modes determined by a combination of the angular speed of the sail and its angular position are stored, among which the candle of the abano moves,
- la placa de control envía las correspondientes instrucciones a la placa de potencia (circuito driver motor) que, a su vez, transmite dichas instrucciones al motor mediante las correspondientes intensidades eléctricas que recorren sus bobinas, lo que genera el movimiento discontinuo de dicho motor, que se transmite al eje de giro que mueve la vela del abano, - the control board sends the corresponding instructions to the power plate (motor driver circuit) which, in turn, transmits said instructions to the motor through the corresponding electrical currents that run through its coils, which generates the discontinuous movement of said motor, which is transmitted to the axis of rotation that moves the candle of the fertilizer,
y. Y.
- un conjunto mecanismo, accionado por el motor, que permite el accionamiento mecánico del abano, y hace que la vela del abano gire a la velocidad angular predeterminada entre las posiciones angulares previamente establecidas por la placa de control.  - a mechanism assembly, driven by the motor, which allows the mechanical drive of the fan, and causes the fan's candle to rotate at the predetermined angular speed between the angular positions previously established by the control plate.
En la memoria de la placa de control hay grabadas señales de paso y dirección en forma de grupos o mapas, que son las que generan las temporizacio- nes que caracterizan el movimiento del motor. Estos mapas caracterizan la cine- mática de cada uno de los movimientos que el aparato puede realizar, pudiendo así establecerse mapas de distintas configuraciones como arranque (etapa transí- toria) y mapas para diferentes velocidades, aceleraciones o aperturas. In the control board memory, step and direction signals are recorded in the form of groups or maps, which generate the timings that characterize the movement of the motor. These maps characterize the kinematics of each of the movements that the device can perform, thus being able to establish maps of different configurations as starting (transitional stage). toria) and maps for different speeds, accelerations or openings.
El conjunto mecanismo, que es el encargado de generar el impulso de la vela, comprende:  The whole mechanism, which is responsible for generating the momentum of the candle, includes:
- un motor paso a paso cuyo movimiento se transmite a través de una transmisión a, - a stepper motor whose movement is transmitted through a transmission to,
- un eje de salida motor, que está sujeto mediante unos rodamientos,  - a motor output shaft, which is secured by means of bearings,
- un eje secundario, apoyado en los rodamientos, que recibe el movimiento del eje de salida motor a través de la correa, y transmite su movimiento a un engranaje, ayudado de la correa,  - a secondary shaft, supported by the bearings, which receives the movement of the motor output shaft through the belt, and transmits its movement to a gear, assisted by the belt,
donde un engranaje está solidariamente unido al eje principal y transmite el movimiento de dicho eje secundario al eje principal . De esta manera queda asegurada la posición del eje principal dentro del conjunto mediante unos rodamientos, a la vez que un tope impide que el eje secundario y los órganos adyacentes a él se desplacen durante el giro del eje principal . where a gear is jointly attached to the main axis and transmits the movement of said secondary axis to the main axis. In this way, the position of the main shaft within the assembly is secured by means of bearings, while a stop prevents the secondary axis and the organs adjacent to it from moving during the rotation of the main axis.
Un posicionador del eje principal determina el ángulo de giro de dicho eje principal, siendo detectada dicha posición por el circuito de final de carrera. Así se dan instrucciones a la placa de control y la placa de potencia para cambiar de ciclo y, por tanto, mandar al motor a girar en sentido contrario al que venía haciéndolo para generar así el movimiento de vaivén del abano.  A positioner of the main axis determines the angle of rotation of said main axis, said position being detected by the limit switch circuit. This gives instructions to the control board and the power plate to change the cycle and, therefore, send the motor to rotate in the opposite direction to the one that was doing so to generate the movement of the swinging of the fan.
El usuario da las instrucciones a la unidad electrónica (integrada por una fuente de alimentación, una placa de potencia, y una placa de control), a través de un circuito de detección de las señales de infrarrojos, provenientes de un mando a distancia, y que está protegido por una tapa o visor.  The user gives instructions to the electronic unit (consisting of a power supply, a power board, and a control board), through a circuit for detecting infrared signals, from a remote control, and which is protected by a cover or viewfinder.
Además, la placa de control dispone de un programa de seguridad de manera que si durante el movimiento de la vela se produce un choque, se produce la desconexión del motor, haciendo que la vela adopte la configuración de energía potencial mínima.  In addition, the control board has a safety program so that if a crash occurs during the movement of the sail, the motor is disconnected, causing the candle to adopt the minimum potential energy setting.
La vela del abano está fijada a un soporte que, a su vez, está unida al eje principal del conjunto mecanismo por unos brazos, de manera que el movimiento de giro del eje principal se transmite mediante los brazos y el soporte a la vela.  The candle of the abano is fixed to a support which, in turn, is connected to the main axis of the mechanism assembly by some arms, so that the turning movement of the main axis is transmitted by means of the arms and the support to the candle.
En una configuración alternativa, los brazos son telescópicos, pudiendo extenderse o acortarse su longitud en función de las necesidades de la estancia en la que el abano se ubica.  In an alternative configuration, the arms are telescopic, and their length may be extended or shortened depending on the needs of the room in which the fertilizer is located.

El abano que esta invención propone consta de un nuevo sistema de gene- ración del movimiento de vaivén de la vela. Por tanto, la disposición genérica del abano es similar a la descrita en el estado de la técnica conocido, por ejemplo, en el documento WO 03/072950 A1 , estando las diferencias de esta invención en el conjunto del mecanismo de impulsión de la vela en sí, que se describen a continuación. La figura 3 muestra una configuración genérica de un abano.  The fertilizer proposed by this invention consists of a new system for generating the reciprocating movement of the sail. Therefore, the generic arrangement of the fertilizer is similar to that described in the known state of the art, for example, in WO 03/072950 A1, the differences of this invention being in the whole of the mechanism for driving the candle in Yes, described below. Figure 3 shows a generic configuration of a fan.
El sistema de la presente invención permite conseguir un movimiento suave, incluso programado, de forma que la cinemática del mismo es configurable en el momento de la fabricación, pudiendo disponer igualmente de varios comportamientos seleccionares por el usuario, todo ello con un nivel sonoro inferior al de cualquier dispositivo similar y adecuado a sus condiciones de uso.  The system of the present invention allows to achieve a smooth movement, even programmed, so that the kinematics thereof is configurable at the time of manufacture, being able to also have several user-selectable behaviors, all with a sound level lower than of any device similar and appropriate to its conditions of use.
El sistema que acciona la vela del abano está compuesto por un motor y por un control electrónico que es capaz de accionar dicho motor de forma casi continua con la técnica de microstepping (micropasos). Cuando se requiere un control preciso de la velocidad de giro y de la posición angular, los motores paso a paso permiten una buena regulación de estas variables, por lo que resultan una herramienta óptima para regular el movimiento de la vela del abano. El empleo de la técnica de micropasos permite mejorar el control de la posición de la vela del abano, ya que es posible disminuir el ángulo de paso, lo que posibilita otras posiciones intermedias entre las dos posiciones de pasos completos. De esta manera, se puede hacer una mayor regulación de la posición de la vela y de su velocidad de giro.  The system that drives the candle of the fertilizer is composed of a motor and an electronic control that is capable of operating said motor almost continuously with the microstepping technique. When precise control of the rotation speed and angular position is required, the stepper motors allow a good regulation of these variables, making them an optimal tool to regulate the movement of the candle of the fan. The use of the micropassing technique makes it possible to improve the control of the position of the candle of the fertilizer, since it is possible to reduce the angle of passage, which allows other intermediate positions between the two positions of complete steps. In this way, a greater regulation of the position of the sail and its speed of rotation can be made.
Tal y como se aprecia en la figura 1 , la unidad de impulsión del abano consta de una chapa soporte (27) que se fija, por ejemplo, al techo del local donde se va a ubicar el abano con objeto de mover su vela (57). El anclaje a través de la chapa soporte (27) se hace por medio de tornillos y, de forma elástica, gra- cias a los correspondiente topes o "silent block" (24) ayudados por unos separadores (28) a los que se acoplan las arandelas (25) y las tuercas (26). El resto del mecanismo es una unidad cerrada que el fabricante suministra así al usuario, de forma que este mecanismo se cuelga de los dos ganchos de colgado (29) de forma que puede hacerse la conexión eléctrica de la red eléctrica del edifico al me- canismo del abano por medio de la regleta (20). El último paso en la instalación sería colgar la vela (57) del eje principal (32) del accionamiento, que sale del con- junto mecanismo (8). As can be seen in Figure 1, the drive unit of the fan consists of a support plate (27) that is fixed, for example, to the ceiling of the premises where the fan is to be located in order to move its candle (57 ). The anchorage through the support plate (27) is made by means of screws and, in an elastic way, thanks to the corresponding stops or "silent block" (24) aided by separators (28) to which they are coupled the washers (25) and the nuts (26). The rest of the mechanism is a closed unit that the manufacturer thus supplies to the user, so that this mechanism is hung from the two hanging hooks (29) so that the electrical connection of the building's electrical network to the mechanism can be made of the fertilizer by means of the strip (20). The last step in the installation would be to hang the sail (57) from the main shaft (32) of the drive, which leaves the con- together mechanism (8).
Sobre dicha base de la unidad (17) se ubican el resto de componentes, tanto de control electrónico como de movimiento de la vela. La parte electrónica está integrada por una fuente de alimentación (21 ), una placa de potencia (16) (o circuito driver del motor) y una placa de control (18); estas dos placas están protegidas por una tapa (15). Existe un circuito detector de final de carrera (46) (véase la figura 2) que realimenta el sistema de control. También existe un circuito (4) de detección de las señales de infrarrojos provenientes del mando a distancia y que está protegido por una tapa o visor (2). Por otra parte está el subconjunto mecánico de motor (53) y reductora que se anclan a la base (17). Como se verá posteriormente, todo el sistema mecánico de motor-reductora está envuelto por material aislante (30 y 31 ) que reduce el ruido interno. Este conjunto de base y moto-reductora están cerrados por tapas embellecedoras (19 y 3) que permite personalizar el aparato con diferentes acabados.  On said base of the unit (17) are located the rest of the components, both electronic control and movement of the candle. The electronic part is integrated by a power supply (21), a power board (16) (or motor driver circuit) and a control board (18); These two plates are protected by a cover (15). There is a limit switch detector circuit (46) (see Figure 2) that feeds the control system. There is also a circuit (4) for detecting infrared signals from the remote control and which is protected by a cover or viewfinder (2). On the other hand there is the mechanical subset of motor (53) and reducer that are anchored to the base (17). As will be seen later, the entire mechanical motor-reduction system is wrapped in insulating material (30 and 31) that reduces internal noise. This base and moto-reducer assembly are closed by trim covers (19 and 3) that allow you to customize the device with different finishes.
La fuente de alimentación (21 ) suministra la energía eléctrica necesaria para el funcionamiento del dispositivo a través de unos cables (no representados en las figuras) utilizando la regleta (20); una tapa (22) de la fuente de alimentación (21 ) se atornilla a este elemento mediante los tornillos (23).  The power supply (21) supplies the electrical energy necessary for the operation of the device through cables (not shown in the figures) using the strip (20); A cover (22) of the power supply (21) is screwed to this element by means of the screws (23).
En el control electrónico del dispositivo están programadas las distintas modalidades de movimiento del eje principal (32) que, a su vez, genera el movimiento de la vela (57) del abano. Para ello se emplea la placa de control (18), que manda a la placa de potencia (16) el programa a efectuar según las necesidades que reciba de las instrucciones enviadas por el usuario, y que llegan a través del visor de infrarrojos (2), ubicado en la tapa embellecedor (1 ), hasta el circuito de infrarrojos (4).  In the electronic control of the device, the different modes of movement of the main shaft (32) are programmed, which, in turn, generates the movement of the candle (57) of the fan. For this, the control board (18) is used, which sends the program to be carried out to the power board (16) according to the needs that it receives from the instructions sent by the user, and that arrive through the infrared viewfinder (2 ), located on the trim cover (1), to the infrared circuit (4).
La placa de control (18) consta de unas memorias y microprocesadores que son los encargadas de gestionar el movimiento del abano. En las distintas memorias están almacenadas los modos de funcionamiento del abano (básica- mente elección de la velocidad angular y la posición angular de la vela (57) del abano) y, según las instrucciones que haya dado el usuario, se pondrá en marcha un programa u otro, es decir, una combinación de velocidad angular de la vela (57) y posición angular entre las que se mueve la vela (57) del abano.  The control board (18) consists of memories and microprocessors that are responsible for managing the movement of the fertilizer. In the various memories the operating modes of the fan are stored (basically choice of angular speed and angular position of the candle (57) of the fan) and, according to the instructions given by the user, a program or another, that is, a combination of the angular velocity of the sail (57) and angular position between which the candle (57) of the fan moves.
Así, una vez seleccionado un programa por el usuario, la placa de control (18) envía las correspondientes instrucciones a la placa de potencia (16) (circuito driver motor); las instrucciones que esta placa de potencia (16) transmite al motor paso a paso (53) resultan ser básicamente intensidades eléctricas que recorren sus bobinas, lo que genera el movimiento de dicho motor paso a paso (53) que se transmite mediante el conjunto mecanismo (8) al eje de giro (32) de la vela (57) del abano, y hace que la vela (57) del abano gire a la velocidad angular predeterminada entre las posiciones angulares previamente establecidas. Con este método se consigue un alto control del movimiento con unos niveles de ruido muy bajos. Thus, once a program has been selected by the user, the control board (18) sends the corresponding instructions to the power board (16) (motor driver circuit); the instructions that this power plate (16) transmits to the engine step by step (53) turns out to be basically electrical currents that run through its coils, which generates the movement of said stepper motor (53) that is transmitted by means of the mechanism assembly (8) to the axis of rotation (32) of the sail (57) of the fan, and causes the candle (57) of the fan to rotate at the predetermined angular velocity between the previously established angular positions. With this method, high movement control is achieved with very low noise levels.
Las señales de paso y dirección están grabadas en la memoria de la placa de control (18) en forma de grupos (mapas) y son las que generan las temporiza- dones que caracterizan el movimiento. Estos mapas caracterizan la cinemática de cada uno de los movimientos que el aparato puede realizar, de esta forma se pueden establecer mapas de arranque (etapa transitoria), mapas para diferentes velocidades, aceleraciones, aperturas, etc. Otra ventaja de utilizar este sistema de motor paso a paso es el alto valor del par en el momento del arranque y a bajas velocidades, que es necesario para iniciar el movimiento.  The step and direction signals are recorded in the memory of the control board (18) in the form of groups (maps) and are the ones that generate the timings that characterize the movement. These maps characterize the kinematics of each of the movements that the device can perform, in this way you can establish boot maps (transient stage), maps for different speeds, accelerations, openings, etc. Another advantage of using this stepper motor system is the high torque value at the time of starting and at low speeds, which is necessary to start the movement.
La placa de control (18) y la placa de potencia (16) (circuito driver motor) se encuentran protegidas por una tapa (15) que se fija mediante los tornillos (14). La base unidad (17) se cierra en sus extremidades por sendas tapas laterales (19), así como por la tapa (3) que hacen de embellecedores como ya se ha indicado. Un aislamiento de la base (30) así como un aislamiento de la tapa (31 ) hacen que se reduzca el sonido que se emite en el movimiento del conjunto del mecanismo (8), que se pasa a explicar a continuación.  The control board (18) and the power board (16) (motor driver circuit) are protected by a cover (15) that is fixed using the screws (14). The base unit (17) is closed at its extremities by two side covers (19), as well as by the cover (3) that make trims as already indicated. An insulation of the base (30) as well as an insulation of the cover (31) reduce the sound emitted in the movement of the mechanism assembly (8), which is explained below.
Dicho conjunto del mecanismo (8) es el encargado de realizar el movimien- to de vaivén que se transmite al eje principal (32), y se encuentra alojado en el base unidad (17). El eje principal (32) atraviesa las tapas laterales (19) a través de los correspondientes agujeros que éstas poseen. A su vez, el conjunto del mecanismo (8) se fija a la carcasa de la base unidad (17) mediante los correspondiente topes o "silent block" (9), ayudados por unos tornillos (6) y sus correspon- dientes arandelas (7). El eje principal (32) queda sujeto mediante las bridas soporte (12) gracias a unos rodamientos (13), que se fijan a la carcasa de la base unidad (17) mediante unos tornillos (10) y sus correspondientes arandelas (1 1 ).  Said mechanism assembly (8) is responsible for performing the reciprocating movement that is transmitted to the main axis (32), and is housed in the unit base (17). The main shaft (32) passes through the side covers (19) through the corresponding holes they have. In turn, the mechanism assembly (8) is fixed to the housing of the unit base (17) by means of the corresponding stops or "silent block" (9), aided by screws (6) and their corresponding washers ( 7). The main shaft (32) is secured by the support flanges (12) thanks to bearings (13), which are fixed to the housing of the unit base (17) by means of screws (10) and their corresponding washers (1 1) .
El ya mencionado circuito de infrarrojos (4) se une a la tapa (3) de la unidad mediante el tornillo (5), estando conectado este circuito de infrarrojos (4) con su correspondiente visor (2). La tapa embellecedor (1 ) cubre la tapa (3) de la unidad, dando un acabado estético acorde con el gusto del usuario. La figura 2 muestra una vista en explosión del conjunto mecanismo (8) que permite el accionamiento mecánico del abano. El motor eléctrico paso a paso (53) es accionado según las instrucciones dadas por la placa de control (18) y la placa de potencia (o circuito driver motor) (16); el motor (53) está unido al lateral del soporte motor (44) mediante los correspondiente topes o "silent block" (45), empleando unos separadores (48). Unos tornillos (50), también con sus correspondiente topes o "silent block" (49), aseguran la fijación del motor (53) con el lateral del soporte motor (44). Los prisioneros (52) aseguran la fijación del motor (53). The aforementioned infrared circuit (4) is attached to the cover (3) of the unit by means of the screw (5), this infrared circuit (4) being connected to its corresponding viewfinder (2). The trim cover (1) covers the cover (3) of the unit, giving an aesthetic finish according to the user's taste. Figure 2 shows an exploded view of the mechanism assembly (8) that allows the mechanical operation of the fan. The stepper electric motor (53) is driven according to the instructions given by the control board (18) and the power board (or driver motor circuit) (16); the motor (53) is connected to the side of the motor support (44) by means of the corresponding stops or "silent block" (45), using spacers (48). Screws (50), also with their corresponding stops or "silent block" (49), ensure the fixing of the motor (53) with the side of the motor support (44). The prisoners (52) ensure the fixing of the engine (53).
Para resolver las necesidades totales de par, el sistema incorpora una re- ductora basada en poleas y correas síncronas, de forma que prácticamente no existen juegos en las inversiones del sistema, además de reproducir los movimientos con fidelidad. Además, este sistema genera un reducido nivel de ruido, especialmente si se compara con el producido por otros sistemas como engranájes, cadenas o biela-manivela.  In order to solve the total torque needs, the system incorporates a synchronous pulley and belt-based reducer, so that there are practically no games in the system's investments, in addition to reproducing the movements with fidelity. In addition, this system generates a reduced level of noise, especially when compared to that produced by other systems such as gears, chains or crank-crank.
El movimiento del motor (53) se transmite a través de la transmisión (51 ) al eje de salida motor (41 ). Este eje de salida motor (41 ), sujeto mediante unos rodamientos (39), transmite su movimiento a un eje secundario (38) a través de la correa (37). Una polea (40) garantiza este movimiento. El eje secundario (38), apoyado en los rodamientos (36), transmite su movimiento al engranaje (43), ayudado de la correa (42). Este engranaje (43), solidariamente unido al eje principal (32), transmite el movimiento de dicho eje secundario (38) al eje principal (32); los rodamientos (35) aseguran la posición del eje principal (32) dentro del conjunto. El tope (54) impide que el eje secundario y los órganos adyacentes a él se des- placen durante el giro del eje principal (32).  The movement of the motor (53) is transmitted through the transmission (51) to the motor output shaft (41). This motor output shaft (41), secured by means of bearings (39), transmits its movement to a secondary shaft (38) through the belt (37). A pulley (40) guarantees this movement. The secondary shaft (38), supported by the bearings (36), transmits its movement to the gear (43), assisted by the belt (42). This gear (43), integral to the main shaft (32), transmits the movement of said secondary shaft (38) to the main shaft (32); The bearings (35) ensure the position of the main shaft (32) within the assembly. The stop (54) prevents the secondary axis and the organs adjacent to it from moving during the rotation of the main axis (32).
Este eje principal (32) está unido al soporte (56) del cual pende la vela (57) del abano mediante unos brazos (55), de manera que el giro del eje (32) supone un desplazamiento angular del soporte (56) de la vela (57), lo que genera el movimiento de la vela (57) en sí, generando una corriente de aire.  This main shaft (32) is attached to the support (56) from which the candle (57) hangs from the fan by means of arms (55), so that the rotation of the shaft (32) involves an angular displacement of the support (56) of the candle (57), which generates the movement of the candle (57) itself, generating a stream of air.
En una configuración alternativa, los brazos (55) son telescópicos, pudien- do extenderse o acortarse su longitud en función de las necesidades de la estancia en la que el abano se ubica.  In an alternative configuration, the arms (55) are telescopic, and their length may be extended or shortened depending on the needs of the room in which the fertilizer is located.
Un posicionador (47) del eje principal (32) determina el ángulo de giro de dicho eje principal (32); esta posición es detectada por el circuito de final de ca- rrera (46), que así da instrucciones a la placa de control (18) y la placa de potencia (16) a cambiar de ciclo y por tanto mandar al motor (53) a girar en sentido con- trario al que venía haciéndolo para generar así el movimiento de vaivén del abano. Los laterales (33) cierran el conjunto del mecanismo (8), mediante los correspondientes tornillos (34). A positioner (47) of the main axis (32) determines the angle of rotation of said main axis (32); This position is detected by the end-of-race circuit (46), which thus instructs the control board (18) and the power plate (16) to change cycles and therefore send the motor (53) turn counter It was the one who had been doing it to generate the movement of the sway of the abano. The sides (33) close the mechanism assembly (8), using the corresponding screws (34).
El dispositivo dispone de un programa de seguridad almacenado en la placa de control (18) de manera que si durante el movimiento de la vela se produce un choque (por ejemplo, con algún objeto o persona), se produce la desconexión del motor, haciendo que la vela adopte la configuración de energía potencial mínima.  The device has a safety program stored on the control board (18) so that if during the movement of the candle a crash occurs (for example, with some object or person), the motor disconnection occurs, making The candle adopts the minimum potential energy configuration.
