  • DC Motors | Machine Design

    DC Motors. Control is obtained by weakening the shuntfield current of the motor to increase speed and to reduce output torque for a given armature current. Since the rating of a dc motor is determined by heating, the maximum permissible armature current is approximately constant over the speed range.
