Abstract

Inventia se refera la o metoda si un sistem de reglare a turatiei motoarelor de curent continuu de mica putere, excitate cu magneti permanenti. Reglarea turatiei se face pe seama variatiei tensiunii medii la bornele circuitului rotoric, realizata prin divizarea numarului de pulsuri de tensiune sinusoidala obtinute printr-o unda sinusoidala de tensiune de medie frecventa, în urma redresarii acesteia de puntea unui convertor Gaudet cu comutatie naturala. Aceste pulsuri sînt aplicate indusului motorului cu ajutorul tiristorului convertorului Gaudet.The invention relates to a method and system for regulating the speed of low-power DC motors excited with permanent magnets. The speed adjustment is based on the variation in the mean voltage at the rotor circuit terminals, by dividing the number of sinusoidal voltage pulses obtained by a sinewave voltage of medium frequency, as it recovers it from the bridge of a Gaudet switch with natural switching. These pulses are applied to the motor induced by the thyristor of the Gaudet converter.
