DRIVING METHOD OF ELECTRIC ROTATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an easy-to-implement driving method of an electric rotating machine in which a driving pulse can be synchronized easily.

SOLUTION: In the driving method of the electric rotating machine for driving two rotors independently by a hybrid current from a polyphase inverter, a stator coil of the electric rotating machine is divided into such sets that the total sum of currents becomes zero. The neutral of the stator coil in each set is interconnected and a driving pulse is fed independently to an inverter arm of the polyphase inverter driving the stator coil of each set and an inverter arm for driving the stator coil of the other set.
