    				| 1. | What is the principle of dynamic braking of the DC motor with separate excitation and how is this done in practice? | 
| Answer» 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. | |
