Answer:
The full load slip of an induction motor varies from:
b. 2 - 7%
Step-by-step explanation:
The full load slip of an induction motor refers to the difference between the synchronous speed and the actual speed of the motor when it is running at full load. The synchronous speed is the speed at which the rotating magnetic field would move if it were rotating at the same frequency as the stator's electrical supply.
The slip is given by the formula:
Slip = (Synchronous Speed - Actual Speed) / Synchronous Speed
The slip is expressed as a percentage of the synchronous speed. For an induction motor operating at full load, the typical range of slip is between 2% and 7%. This means that the rotor of the motor is rotating at a speed slightly lower than the synchronous speed, which is necessary for the motor to generate the required torque and operate efficiently.
