A three phase, wound rotor induction motor is to be operated with slip energy recovery in the constant torque mode, when it delivers an output power Po at slip s. Theoretically, maximum power available for recovery at the rotor terminals, is
-
- Po
- Pos
-
Po (1 − s) -
Pos (1 − s)
Correct Option: B
| Tfl = | . | ||
| ωs | r2/sfl |
| and T = | . | ||
| ωs | r2/s |
Given: Tfl = T and V' = (1. 1) V
| ∴ s = |  |  | 2 | ⋅ sfl = 0.03 × | | | 0.6 | = 2.48% | ||
| V' | 1.1 |
