Plugging — sometimes referred to as “reverse current braking” — is possible on both DC motors and AC induction motors. For DC motors, plugging is achieved by reversing the polarity of the armature voltage. Torque is developed in the opposite direction of the motor's rotation, which produces a strong braking effect.

Explanation:
When the terminals of the armature of a DC motor are interchanged, it is called plugging. This action will offer plugging braking, which is a type of dynamic braking.
Plugging:
Plugging is a method of braking a DC motor in which the terminals of the armature are reversed during rotation or while it is still running. This can be done by reversing the polarity of the supply voltage or by connecting a resistor across the armature terminals.
Braking:
Braking is the process of stopping the motion of a motor or any other rotating object. Braking is necessary to prevent accidents and to control the speed of the motor.
Types of Braking:
There are three types of braking in DC motors:
1. Regenerative braking
2. Dynamic braking
3. Plugging braking
Regenerative Braking:
Regenerative braking is a type of braking in which the motor converts its kinetic energy into electrical energy and feeds it back to the supply. This type of braking is used in applications where the motor is driving a load that needs to be decelerated quickly.
Dynamic Braking:
Dynamic braking is a type of braking in which the motor is connected to a resistor that dissipates the energy of the motor as heat. This type of braking is used in applications where the motor is driving a load that needs to be decelerated slowly.
Plugging Braking:
Plugging braking is a type of dynamic braking in which the terminals of the armature are reversed, causing the motor to stop quickly. This type of braking is used in applications where the motor needs to be stopped quickly and the load is not sensitive to sudden stops.
Conclusion:
When the terminals of the armature of a DC motor are interchanged, it is called plugging, and it offers plugging braking, which is a type of dynamic braking. Plugging braking is used in applications where the motor needs to be stopped quickly and the load is not sensitive to sudden stops.
