Which type of ac motor is used in ceiling fan?

There are different types of AC motors used in ceiling fans, depending on the design and performance of the fan. Some of the common types are:-

**Shaded pole motor**: This is the simplest and cheapest type of AC motor, which consists of a single winding and a shaded ring that creates a rotating magnetic field. This type of motor is easy to start, but has low efficiency and torque. It is suitable for small and low-speed ceiling fans. ¹-

**Capacitor start motor**: This is a type of single-phase induction motor, which uses a capacitor to provide a starting torque and improve the power factor. This type of motor has higher efficiency and torque than shaded pole motors, but also higher cost and noise. It is suitable for medium-sized and high-speed ceiling fans. ²-

**Capacitor start and run motor**: This is a variation of the capacitor start motor, which uses two capacitors instead of one. One capacitor is used for starting, and the other is used for running. This type of motor has better efficiency, torque, and power factor than capacitor start motors, but also higher cost and complexity. It is suitable for large and high-speed ceiling fans. ²-

**Permanent split capacitor (PSC) motor**: This is another variation of the capacitor start motor, which uses only one capacitor that is permanently connected to the winding. This type of motor has lower starting torque, but higher running efficiency and lower noise than capacitor start motors.

It is suitable for medium-sized and variable-speed ceiling fans. ²I hope this answer helps you understand the different types of AC motors used in ceiling fans.
