TWO-PHASE ROTATING ELECTRICAL MACHINE CONTROL DEVICE AND CONTROL SYSTEM FOR TWO-PHASE ROTATING ELECTRICAL MACHINE

摘要

A two-phase rotating electrical machine control device which controls a two-phase three-wire type rotating electrical machine provided with two coils, wherein, prior to executing switching control to switch the orientation of an excitation current flowing through one of the two coils, it is possible to cause the current flowing through the coil in which the orientation of the excitation current is to be switched to flow backwards.
