ROTATING ELECTRIC MACHINE CONTROL SYSTEM

摘要

Provided is a rotating electric machine control system which, in a hybrid system including a pair of rotating electric machines for receiving power supply from a common battery, one rotating electric machine serving as a generator and the other rotating electric machine serving as a motor, ensures protection of an area from the battery to an inverter by preventing an overcurrent from flowing. The rotating electric machine control system including a rotating electric machine, and an inverter for controlling an electric current flowing through the rotating electric machine, which is disposed between a battery and the rotating electric machine, comprises a battery power deriving means for deriving battery power supplied from the battery from at least the rotational speed of the rotating electric machine and required torque, and a torque restricting means for restricting the output torque of the rotating electric machine. The torque restricting means restricts the output torque according to the magnitude of the battery power derived by the battery power deriving means.
