La bomba de vaciado 1, mostrada en las figuras 1 a 3, comprende un motor eléctrico 2 síncrono que tiene un estator 4 fijo y un rotor 3 de imanes permanentes solidario con un eje motriz 9, un rodete 5 acoplado al rotor 3 a través de dicho eje motriz 9, y una capota 7 que aloja en su interior el motor eléctrico 2, mientras que el rodete 5 se dispone en el exterior de dicha capota 7.The drain pump 1, shown in figures 1 to 3, comprises a synchronous electric motor 2 having a stator 4 fixed and a rotor 3 of permanent magnets integral with a drive shaft 9, an impeller 5 coupled to the rotor 3 through said drive shaft 9, and a hood 7 that houses the electric motor 2 inside, while impeller 5 is disposed outside said hood 7.
El motor eléctrico 2, mostrado en detalle en las figuras 2 y 3, es un motor trifásico del tipo BLDC, es decir, de corriente continua y sin escobillas, y comprende un cuerpo 21 sustancialmente cilíndrico, que tiene una primera parte 22 coaxial y hueca en cuyo interior se inserta el rotor 3 y sobre cuyo exterior se acopla un estator 4 de polos salientes, y una segunda parte 23, coaxial y continua a la primera parte 22, de mayor diámetro y de menor longitud que dicha primera parte 22, a través de la cual se fija el motor eléctrico 2 a la capota 7. Dicha segunda parte 23 tiene un orificio 23a coaxial y pasante, a través del cual se inserta el rotor 3 y el eje motriz 9 en el interior de la primera parte 22, e incluye en un extremo una junta de estanqueidad 12 para la fijación estanca dentro del cuerpo hidráulico 6, mientras que en el extremo opuesto incluye un reborde perimetral 24 exterior para su fijación a la capota 7.The electric motor 2, shown in detail in the Figures 2 and 3, is a three-phase motor of the BLDC type, that is, of DC and brushless current, and comprises a body 21 substantially cylindrical, having a first coaxial part 22 and hollow inside whose rotor 3 is inserted and on whose outside a stator 4 of protruding poles is coupled, and a second part 23, coaxial and continuous to the first part 22, of greater diameter and of shorter than said first part 22, through which fix the electric motor 2 to the hood 7. Said second part 23 it has a coaxial and through hole 23a, through which it insert rotor 3 and drive shaft 9 inside the first part 22, and includes at one end a seal 12 for the tight fitting inside the hydraulic body 6, while in the opposite end includes an outer perimeter flange 24 for its hood attachment 7.
El motor eléctrico 2 de la realización mostrada tiene el estator 4 en forma hexagonal e incluye tres polos salientes 4b sobre los cuales se arrollan unos bobinados 11 conectados eléctricamente a una placa de circuito impreso 20, ocupando dicho motor eléctrico 2 un volumen máximo definido por un diámetro D1 aproximado de 64 mm correspondiente a un circulo circunscrito en el estator 4 y una primera longitud L1 aproximada de 15 mm de dicho estator 4, siendo una segunda longitud L2, del estator 4 junto con el bobinado 11 respectivo, de 34 mm.The electric motor 2 of the embodiment shown It has stator 4 in hexagonal shape and includes three poles projections 4b on which windings 11 are wound electrically connected to a printed circuit board 20, said electric motor 2 occupying a maximum volume defined by a diameter D1 approximately 64 mm corresponding to a circle circumscribed in stator 4 and a first approximate length L1 15 mm of said stator 4, being a second length L2, of the stator 4 together with the respective winding 11, 34 mm.
Por otro lado, dicho motor eléctrico 2 tiene un entrehierro existente entre el estator y el rotor uniforme con el objeto de que la reluctancia del circuito magnético resultante proporcione un par adherente mínimo, proporcionando una tensión inducida senoidal en bornes (en los bornes de una fase y el neutro de una conexión estrella) de un valor eficaz máximo 3,7 x10^{-4} V/(vueltas x Hz). El motor eléctrico 2 desarrolla una potencia hidráulica entre 0 y 5 W, siendo capaz de trabajar a distintos puntos par/velocidad, con un par motor de 0 a 0,06 Nm, a una velocidad de rotación entre 30 y 60 Hz.On the other hand, said electric motor 2 has a existing air gap between the stator and the uniform rotor with the object of reluctance of the resulting magnetic circuit provide minimal adherent torque, providing tension induced sinusoidal in terminals (in the terminals of a phase and the neutral of a star connection) of a maximum effective value 3.7 x10-4 V / (turns x Hz). The electric motor 2 develops a power hydraulic between 0 and 5 W, being able to work at different torque / speed points, with a torque of 0 to 0.06 Nm, at a rotation speed between 30 and 60 Hz.
El motor eléctrico 2 puede trabajar a velocidades mayores de lo habitual para solventar problemas de cebado y para obtener ciclos de lavado más cortos. En este tipo de motores no se dan los característicos puntos muertos, es decir posiciones angulares del rotor donde los flujos magnéticos del rotor y del estator se alinean, no generando par motor. Por otro lado, la disipación de calor del motor eléctrico 2 es más simétrica que otros motores conocidos del estado de la técnica. El modo de comandar dicho motor eléctrico 2 implica la sensorizacion de algunos de los parámetros de funcionamiento tales como velocidad y consumo de corriente, los cuales pueden ser utilizados para detener el funcionamiento del motor eléctrico 2 cuando no hay agua, mejorando los niveles de ruido y obteniendo ciclos de trabajo más cortos y por tanto mejor eficiencia energética.The electric motor 2 can work at higher speeds than usual to solve problems of priming and to obtain shorter wash cycles. In this kind of engines are not given the characteristic dead spots, that is angular positions of the rotor where the magnetic fluxes of the rotor and stator line up, not generating torque. For another side, the heat dissipation of the electric motor 2 is more symmetrical than other engines known in the state of the art. Mode command said electric motor 2 implies the sensorization of some of the operating parameters such as speed and consumption of current, which can be used to stop the operation of electric motor 2 when there is no water, improving noise levels and obtaining shorter work cycles and therefore better energy efficiency.
Por otro lado, la conexión eléctrica de los bobinados 11 se realiza mediante una placa de circuito impreso 13 del tipo PCB, que permite cambiar el tipo de conexión de forma rápida, modificando únicamente dicha placa de circuito impreso 13. La placa de circuito impreso 13 incluye unos orificios de fijación 13a de dicha placa de circuito impreso 13 al motor eléctrico 2, y unos puntos de conexión 13b de los hilos de los bobinados 11 correspondientes. El cuerpo 21 incluye unos salientes 25 de sección circular, dispuestos alternos con respecto a los bobinados 11, los cuales se extienden axiales desde la segunda parte 23 a lo largo de la primera parte 22. Cada saliente 25 tiene en el extremo libre, una base 25b desde la cual se extiende concéntrico y axial, un pivote 25c de sección cilíndrica y de menor diámetro que el saliente 25, de modo que el pivote 25c de cada saliente 25 atraviesa la placa de circuito impreso 13, apoyándose la placa de circuito impreso 13 sobre la base 25b. De este modo, la placa de circuito impreso 13, y por tanto los terminales de conexión 13b, se mantienen a una misma cota A1 con respecto al cuerpo 21. Si la placa de circuito impreso 13 se fijara sobre el propio estator 4, la cota A1 variaría, dado que la fabricación del estator 4 no es siempre homogénea al variar el número de chapas que to conforman y por tanto la altura total de dicho estator 4.On the other hand, the electrical connection of windings 11 is realized by means of a printed circuit board 13 PCB type, which allows you to change the type of connection fast, modifying only said printed circuit board 13. The printed circuit board 13 includes fixing holes 13a of said printed circuit board 13 to the electric motor 2, and connection points 13b of the winding wires 11 corresponding. The body 21 includes some protrusions 25 of section circular, arranged alternately with respect to windings 11, the which extend axially from the second part 23 along the first part 22. Each projection 25 has at the free end, a base 25b from which concentric and axial extends, a pivot 25c of cylindrical section and smaller in diameter than the projection 25, so that the pivot 25c of each projection 25 passes through the printed circuit board 13, supporting the circuit board printed 13 on the basis 25b. In this way, the circuit board printed 13, and therefore the connection terminals 13b, is maintain at the same level A1 with respect to the body 21. If the printed circuit board 13 will be fixed on the stator 4 itself, the dimension A1 would vary, since the manufacture of stator 4 is not always homogeneous by varying the number of sheets that make up and therefore the total height of said stator 4.
La bomba de vaciado 1 permite incluir un inverter o circuito de comando del motor eléctrico 2 dentro del propio motor eléctrico 2, para lo cual bastaría con modificar la placa de circuito impreso 13.The drain pump 1 allows to include a inverter or command circuit of electric motor 2 inside the own electric motor 2, for which it would be enough to modify the printed circuit board 13.
La bomba de vaciado 1 de la invención es adaptable a cualquier configuración de un cuerpo hidráulico 6 de desagüe en donde es insertada, y de tal manera que puede utilizar un mismo motor eléctrico 2 para las distintas configuraciones del cuerpo hidráulico 6 variando la capota 7.The drain pump 1 of the invention is adaptable to any configuration of a hydraulic body 6 of drain where it is inserted, and in such a way that you can use the same electric motor 2 for the different configurations of the hydraulic body 6 varying the hood 7.
