Abstract
The electric drive comprises a magnetoelectric synchronous machine with inductor consisting of constant magnets on the armature and three-phase stator winding connected to three amplifier outputs connected by a ring circuit through phase-shifting blocks for the number of machines consisting of RS-circuits and switched the amplifier input and the beginning of the winding of the adjacent synchronous machine phase, thus parameters of RC-circuits are chosen from the condition of occurrence of self-oscillations with the frequency smaller than the frequency of own fluctuations of the synchronous machine.
