Explanation of Solution

A device which is used to convert the electrical energy into mechanical energy is considered as the motor.

In DC motor, direct current (dc) is converted into the mechanical energy.

The expression for the speed of the DC motor is given by,

N=KVIaRaϕ

There are various types of method to control the speed namely flux per pole method, armature resistance method and supply voltage method.

The voltage control method is best suited to operate the DC motor below its normal speed. The applied voltage is controlled by controlling the applied voltage. The voltage is applied to the armature and field, then the motor operates its normal speed. So, the speed of the motor is controlled by varying the applied voltage.

Thus, the way of operation of DC motor to operate below its normal speed are ecplained.
