DRIVE SYSTEM OF MOTOR WITH VARYING MAGNETIC FLOW Russian patent published in 2010 - IPC H02P21/00 H02P6/14 H02K21/00 B60L11/02 

FIELD: electricity.

SUBSTANCE: drive system of motor with varying magnetic flow includes motor (4) on constant magnets, which has constant magnet, inverter (1) for excitation of motor on constant magnets, and magnetisation device for magnetisation current passage in order to control magnetic flow of constant magnet. Constant magnet is varying magnet the magnetic induction of which is varying depending on magnetisation current from inverter (1). Magnetisation current which exceeds saturation zone of magnetisation of magnetic material of varying magnet is passed through magnetisation device. This system improves repeatability of magnetic flow of varying magnet (53) and accuracy of torque moment.

EFFECT: improving control accuracy of torque moment, suppression of transient moment caused by magnetisation process, increasing efficiency and enlarging rotation frequency range.
