Abstract

Inventia se refera la un dispozitiv pentru comanda curentului motoarelor cu curent continuu comutate electronic, cu n trepte de comutare si n bobine, une n este mao mare sau egal cu 2, pentru a se face o reglare a turatiei motorului. Scopul inventiei consta în a se comanda curentul alimentat de treapta de comutare în bobinele statorului cu ajutorul unui semnal de reglare provenit de la filtrul bucla în asa fel încît turatia motorului sa fie mentinuta constanta prin marirea de reglare a curentului motorului pe momentul de srcina variabil. Conform inventiei aceasta se obtine prin aceea ca suma curentilor bobinelor care trec prin punctul neutru este identica cu valoarea data de partea de reglare a turatiei motorului, independent de comanda momentana a diferitelor bobine de stator deoarece în punctul neutru al motorului s-a amplasat o rezistenta si semnalul de tensiune obtinut cu aceasta, proportional cu curentul motorului într+un amplificator operational este supus permanent unei comparatii cu semnalul de reglare dat de partea de reglare.The invention relates to a device for controlling the current of electronically switched DC motors, with n switching steps and n coils, and n is greater than or equal to 2, in order to regulate the motor speed. The purpose of the invention is to control the current supplied by the switching step in the stator coils by means of a control signal from the loop filter in such a way that the motor speed is kept constant by increasing the current of the motor at variable torque. According to this invention, the sum of the coil currents passing through the neutral point is identical to the value given to the motor speed control part, independent of the momentary control of the various stator coils, since the neutral point of the motor has a resistance and the signal the voltage obtained with this, proportional to the motor current in an operational amplifier, is constantly compared to the control signal given by the adjustment part.
