ABSTRACT:
Control system for a motor having a shunt field winding is disclosed. In an electric vehicle, when an accelerator pedal is stepped on at the start, a field current is increased to increase the rotational speed of the motor in accordance with the stepped angle of the pedal. In the operating region where the rotational speed of the motor is not increased in accordance with the increase of the field current, an armature current is in turn increased and inversely the field current is decreased in order to further increase its rotational speed. Thus, an impact at the start can be reduced.
