Electrical Engineering XYZ MCQs
Polarity of supply voltage is reversed in case of which type of braking:
- Plugging
- Regenerative braking
- Dynamic braking
- None of these
Correct answer: 1. Plugging
Explanation: Plugging is the most powerful method of braking an electric motor, consisting of actively applying power to the motor in the opposite direction of its rotation. This is analogous to reversing the engine thrust of a power boat or an airplane in order to quickly bring it to a halt. Continue reading about plugging braking here
Plugging is one of the braking methods used for braking AC motors. List of all braking methods:
- DC injection braking
- Dynamic braking of AC Induction Motors
- Regenerative braking of AC Induction Motors
- Braking using Plugging
