Abstract:
1. A method for controlling a dynamo-electric machine for a vehicle, said dynamo-electric machine comprising a rotator having a field winding and a stator having an armature winding, field current control means for controlling a field current supplied from a direct-current power source to said field winding, and a power converter for converting a power of said direct-current power source into an alternating-current power and supplying the alternating-current power to said armature winding, said method comprising: when said field current control means starts to supply a current to said field winding for starting an internal combustion engine, supplying said alternating-current power by said power converter to said armature winding so that a magnetic flux in a direction opposite to a field flux of said field winding is generated simultaneously with or immediately before starting the supply of the current to said field winding.
