Permanently-excited synchronous machine of electro-mechanical steering system, has three phase windings to which electrical energy is supplied, so that magnetic resistance generated in circumferential direction of stator is changed

摘要

The synchronous machine (8) has three phase windings to which electrical energy is supplied, so that magnetic resistance generated in circumferential direction of stator is changed. The processing units are connected in normal mode, so that torque-dependent signal is generated. Independent claims are included for the following: (1) drive unit for synchronous machine; and (2) method for controlling synchronous machine.
