Question
Slip of 3-Phase Induction Motor in motor mode should always beQuestion 3Select one:a.Zerob.0..1c.Equal to 2d.Greater than 1
Solution
The correct answer is b. 0..1
The slip of a 3-phase induction motor in motor mode should always be between 0 and 1. This is because the slip is defined as the difference between the synchronous speed and the actual rotor speed, divided by the synchronous speed.
In motor mode, the rotor speed is always less than the synchronous speed, so the slip is a positive number less than 1. If the slip was equal to or greater than 1, it would mean that the rotor is stationary or moving in the opposite direction to the magnetic field, which is not possible in motor mode.
