3. SUPPLY VOLTAGE CONTROL
Pulse Width Modulation (PWM)
Both the above mentioned methods cannot provide speed control in the desirable range
Whereas the armature control method involves huge power loss due to its usage of resistor in series with the armature
Therefore, a different method is often desirable – the one that controls the supply voltage to control the motor speed is PWM
