Method of controlling claw-pole synchronous machine

摘要

A method of controlling a claw-pole synchronous machine with enhanced controllability without incurring additional expensiveness. Operation of the claw-pole synchronous machine is controlled through a vector control of an armature voltage and an armature current supplied from an inverter power source in combination with a field current control. When the claw-pole synchronous machine is operated as a generator, the field current is controlled on the basis of a demanded output power and rotation speed of the claw-pole synchronous machine while a field weakening control with the armature current (id) is performed by controlling magnitude and a phase difference angle (Ø) of the armature current (id).
