2005-3-9  Motor Speed • DC motors are variable-speed motors. The speed of a DC motor is changed by changing the current in the field or in the armature. • When the field current is decreased, the field flux is reduced, and the counter emf decreases. This permits more armature current. Therefore, the motor
