Controller for rotating electric machine for vehicle, has magnetic field electric current command restraining unit that limits each phase of line electric current when rotating electric machine functions as electric generator

摘要

A magnetic field electric current command restraining unit (10) limits each phase of the line electric current of the rotating electric machine (2) by controlling the output of a magnetic field electric current command arithmetic unit (9) when the rotating electric machine (2) functions as an electric generator. A line electric current command arithmetic unit (4) feedback-controls the line electric current based on the detected line electric current of the rotating electric machine. The magnetic field electric current command arithmetic unit feedback-controls the magnetic field electric current based on the detected magnetic field electric current of the rotating electric machine. An electric power converter (7) functions as a rectifier or an inverter when the rotating electric machine functions as an electric generator or an electric motor, respectively.
