Electrical Engineering XYZ MCQs
Dynamic braking is very effective for:
- Differential compound motors
- Series motors
- Shunt motors
- Separately excited motors
Correct answer: 4. Separately excited motors
Explanation: Separately excited motors have their field winding excited by an independent external source. This setup allows for the field current to be maintained constant during the dynamic braking process, which is crucial for effective braking. Like shunt motors, the consistent field flux helps generate a steady braking torque throughout the braking process.
