Abstract
A control device for an electromobile provided with a shunt motor includes a pattern generating means for storing, as patterns, armature and field currents capable of generating an output torque with a minimum loss in the driving system of the electromobile to deliver an armature current command and a field current command for generating a specified output torque on the basis of the patterns, an armature control circuit for supplying the shunt motor with an armature current corresponding to the armature current command, and a field control circuit for supplying the shunt motor with a field current corresponding to the field current command. Thus, the torque control of the shunt motor is conducted on the basis of the patterns, and a computer control is applicable to the above control device.
