ABSTRACT:
A method of controlling an electric rotating machine for a vehicle includes an electric rotating machine (1) including a rotator having a field winding (5) and a stator having an armature winding (3), a field current controller (9) for controlling a field current supplied from a direct-current power supply to the field winding (5), and a power converter (6) for converting a direct-current power into an alternating-current power and applying the power to the armature winding (3). When the field current controller (9) starts to supply a current to the field winding (5) for starting an internal combustion engine, the power converter (6) supplies a power to the armature winding (3) so that magnetic flux in a direction opposite to that generated by the field winding (5) is generated simultaneously with or immediately before starting the power supply.
