What is Braking Resistor? Working, Application

The electrical energy generated by a motor or machine is dissipated as heat by the braking resistor when it is decelerated or stopped. The resistor is connected in parallel with the motor and absorbs the energy, which is converted into heat due to the resistance. The dissipated heat enables smooth deceleration or stopping of the motor.

When and How Should I Select a Braking Resistor?
