El regulador de motor de corriente continua objeto de esta invención, es un dispositivo electrónico que permite regular la velocidad de giro del motor, con una gran precisión, alto rendimiento energético, pudiendo enviar energía a la red en el frenado del motor, y de una gran sencillez tecnológica. The DC motor regulator object of this invention, is an electronic device that allows to regulate the speed of rotation of the motor, with great precision, high energy efficiency, being able to send energy to the network in the braking of the motor, and of a Great technological simplicity.
Los reguladores de motor de corriente continua, existentes en el mercado, son mucho más complejos, de poca precisión, bajo rendimiento energético, y no siempre permite enviar energía a la red. The direct current motor regulators, existing in the market, are much more complex, of little precision, low energy efficiency, and it does not always allow to send energy to the network.
Regulador de motor de corriente continua, caracterizado por comprender dos tiristores conectados en antiparalelo y un condensador. El cátodo del tiristor conectado al ánodo del otro tiristor se halla conectado con una fuente de tensión sinusoidal. El cátodo del segundo tiristor conectado al ánodo del primer tiristor, se conecta a un condensador y motor de corriente continua. Los otros extremos de la fuente de tensión sinusoidal, del condensador y motor de corriente continua se conectan entre sí. Donde los terminales de disparo de los tiristores se conectan a una unidad de control de disparo. DC motor regulator, characterized by comprising two thyristors connected in antiparallel and a capacitor. The cathode of the thyristor connected to the anode of the other thyristor is connected to a source of sinusoidal voltage. The cathode of the second thyristor connected to the anode of the first thyristor is connected to a capacitor and DC motor. The other ends of the sine voltage source, the capacitor and the DC motor connect to each other. Where the thyristor trip terminals are connected to a trip control unit.
Los dos tiristores en anti paralelo permiten controlar el nivel de tensión en el condensador por tanto en el motor de corriente continua, y con ella la velocidad. A más tensión más velocidad, y a menos tensión menos velocidad. La unidad de control de disparo, que puede ser analógica o digital, en el fondo compara el valor de la tensión The two thyristors in anti parallel allow to control the level of voltage in the capacitor therefore in the DC motor, and with it the speed. At more tension more speed, and at less tension less speed. The trigger control unit, which can be analog or digital, basically compares the voltage value
sinusoidal con un valor de referencia en función de la velocidad que deseamos, cuando el valor de la sinusoide se hace mayor a ese valor se provoca un disparo en el tiristor TI, si la tensión de la sinusoide es menor que la tensión en el condensador, entra en ON descargándose el condensador, y tomando la tensión en el mismo igual a la de la sinusoide en ese instante. Al proseguir aumentando el valor de la sinusoide, el tiristor TI entra en OFF. sinusoidal with a reference value depending on the speed we want, when the value of the sinusoid becomes greater than that value a trip is thrown in the thyristor TI, if the sinusoid voltage is less than the capacitor voltage, enters ON discharging the capacitor, and taking the voltage in it equal to that of the sinusoid at that moment. As the sinusoid value continues to increase, the thyristor TI goes OFF.
Cuando el valor de la sinusoide se hace menor al de referencia, se provoca el disparo del tiristor T2, si la tensión en el condensador es menor al valor de la sinusoide, el tiristor T2 entra en ON, provocando la carga When the value of the sinusoid becomes smaller than the reference, triggering of the thyristor T2 is triggered, if the voltage in the capacitor is less than the value of the sinusoid, the thyristor T2 goes ON, causing the load

De esta manera, se consigue que la tensión en el condensador, por tanto la aplicada en el motor, quede determinada por una tensión de referencia en la unidad de control de disparo, que será en función de la velocidad deseable, y la velocidad del motor medida por un encoder. In this way, it is achieved that the voltage in the condenser, therefore that applied to the motor, is determined by a reference voltage in the trip control unit, which will be a function of the desirable speed, and the motor speed measured by an encoder.

La unidad de control de disparo de los tiristores, está comprendida por un microcontrolador, que muestrea la señal sinusoidal, y compara con un valor de referencia en función de la velocidad del motor, medible por un encoder. The thyristor trip control unit is comprised of a microcontroller, which samples the sinusoidal signal, and compares with a reference value based on the motor speed, measurable by an encoder.
Se determina el condensador con una intensidad lo suficientemente grande, para que la caida de tensión por el suministro de carga al motor, no sea considerable. The capacitor is determined with a sufficiently large intensity, so that the voltage drop from the load supply to the motor is not considerable.
A la hora de adaptar el pulso de disparo provocado por el microcontrolador, a los tiristores. Se conecta la tensión sinusoidal a un diodo rectificador, cuyo cátodo está conectado a un condensador, de esta manera se consigue el potencial eléctrico máximo en el mismo. Este potencial está conectado al emisor de un transistor pnp, su colector al terminal puerta o disparo de uno de los tiristores, su base conectado al drenador de un transistor Mosfet canal n a través de una resistencia, cuyo terminal puerta se conecta al microcontrolador. Cuando se provoca un pulso por el microcontrolador, este sistema inyecta una intensidad en el terminal puerta del tiristor provocando su conmutación. When adapting the trigger pulse caused by the microcontroller, to the thyristors. The sinusoidal voltage is connected to a rectifying diode, whose cathode is connected to a capacitor, in this way the maximum electrical potential in it is achieved. This potential is connected to the emitter of a pnp transistor, its collector to the door or trigger terminal of one of the thyristors, its base connected to the drain of a Mosfet channel n transistor through a resistor, whose door terminal is connected to the microcontroller. When a pulse is caused by the microcontroller, this system injects an intensity into the thyristor door terminal causing its switching.
