ROTATING ELECTRIC MACHINE FOR VEHICLES

摘要

A rotating electric machine for vehicles has a rotor, a stator having stator windings, MOS module groups as electric power converters, a rotation angle sensor that detects a rotation angle of the rotor, and a control circuit that has a rotation angle sensor abnormality determining section that determines whether abnormalities of the rotation angle sensor exist or not based on a phase voltage induced by the stator windings during the power generation.

主权项

1. A rotating electric machine for vehicles comprising:
a rotor; a stator disposed facing to the rotor and having stator windings; an electric power converter that converts an alternating current voltage induced by the stator windings into a direct current voltage, or converts the direct current voltage applied from outside into the alternating current voltage and applies thereof to the stator windings; a rotation angle sensor that detects a rotation angle of the rotor; and a rotation angle sensor abnormality determining section that determines whether abnormalities of the rotation angle sensor exist based on a phase voltage induced by the stator windings during power generation.
