Question

What is the principle of dynamic braking of the DC motor with separate excitation and how is this done in practice?

Answer 1

Answer:

In Dynamic Braking, a braking resistor Rb is connected across the armature as soon as the DC motor is disconnected from the supply mains. The motor now works as a generator, producing the braking torque. For the braking operation in Dynamic Braking, the motor is connected in two ways.
