ABSTRACT:
The device comprises a variable frequency AC generator with means of exitation supplied by means for controlling exitation current, means for regulation of the frequency of the generator as a function of an index value, means for measuring actual speed of the mobile portion of the motor, and means for comparing actual speed with the index value. According to the invention, the means for controlling the exitation current are connected to the means for comparing actual speed with the index value, and the generator has a high internal reactance.
