Q: What is the principle of operation of an induction motor?

Electromagnetic induction — Induction motors work based on Faraday's law of electromagnetic induction.

Q: The rotating magnetic field in an induction motor is produced by:

AC current in the stator windings — AC current in the stator windings generates the rotating magnetic field.

Q: What determines the synchronous speed of an induction motor?

The number of poles and supply frequency — Synchronous speed is directly proportional to frequency and inversely proportional to the number of poles.

Q: The slip of an induction motor is defined as:

(Synchronous speed - Rotor speed) / Synchronous speed — Slip is the difference between synchronous and rotor speed, normalized by the synchronous speed.

Q: Which part of the induction motor receives power directly from the electrical supply?

Stator — The stator windings are directly connected to the power source.
