Question

Which load torque will be used in regenerative braking?

• A. Fan hype load torque
• B. Frictional load torque
• C. Passive load torque
• D. Archive load torque

Hint:

Regenerative braking is effective with passive load torque, which allows mechanical motion to be converted into electrical energy.

Answer 1

The Correct Option is C

Step 1: Regenerative braking happens when the motor acts as a generator, converting kinetic energy into electrical energy and feeding it back to the supply. 
Step 2: The braking method is efficient when the load torque opposes the rotation direction, allowing the energy to be recaptured. 
Step 3: Passive load torque is the appropriate torque for regenerative braking because:
- It continuously applies torque in the opposite direction. 
- Common in systems like elevators or conveyors, where energy can be stored as electricity. 
Step 4: Evaluating other options:
- Fan hype load torque (Incorrect): Likely a typographical error; fans do not contribute to regenerative braking. 
- Frictional load torque (Incorrect): Frictional torque dissipates energy as heat, not electrical energy. 
- Archive load torque (Incorrect): This term does not apply.
