ELECTROMOTOR CONTROL DEVICE FOR POWER STEERING

摘要

The invention features a device for controlling an electronic switching multiphase motor for power steering. It is characterised in that control circuit (36) of the switching circuit (34) comprises two control loops (42, 44) one of which (42, 52) sequentially supplies signals for switching two of the six switches (T1 to T6) of the commutation circuit (34) to supply power to two phase windings whereas the other (44, 54) sequentially supplies signals for switching a third switch (T1 to T6) to supply power to the third winding phase. The invention is useful for motor vehicles.
