CONTROL DEVICE FOR ROTARY ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To prevent the acceleration/deceleration of connection equipment from being disturbed when executing a variable magnetic field in a variable magnetic field type rotary electric machine.SOLUTION: The variable magnetic field type rotary electric machine comprises a main rotor 40 and a sub rotor 42. The main rotor 40 is fixed to a rotor shaft, and the rotor shaft is connected to connection equipment such as an engine. The sub rotor 42 is rotated relatively to the main rotor 40 and its phase angle is changed. While a rotational acceleration of the connection equipment is being increased, the sub rotor 42 is relatively rotated in such a manner that a rotation direction of the main rotor 40 is matched with a rotation direction of the connection equipment. While the rotational acceleration of the connection equipment is being decreased, the sub rotor 42 is relatively rotated in such a manner that the rotation direction of the main rotor 40 becomes reverse to the rotation direction of the connection equipment.SELECTED DRAWING: Figure 3
