Which type of motor is used in Ceiling Fan – Electrical Machines MCQ#21

by

The type of motor used in Ceiling Fan:

  1. Universal motor
  2. Induction motor
  3. Synchronous motor
  4. DC Motor

Correct answer: 2. Induction Motor

Explanation: The ceiling fan uses a single-phase Induction motor. Very often it is a capacitor start and runs AC Motor. Alongside the single phase induction motor, the BLDC motor is also is popular nowadays for high efficiency, compactness, and controllability.
