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.
