Question: Which type of motor is used in exhaust fan?

Which type of motor is used in fans?

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.

How does a exhaust fan motor work?

Exhaust Fans Use Fan Blades

Like most electric motors, an exhaust fan’s motor uses the electricity’s magnetic field to rotate a metal shaft. The magnetic force created by the electrical flow over copper wires inside the motor overcomes the inertial force of the fan’s shaft and blades, and the fan begins to turn.

Which DC motor is commonly used for fans?

Ceiling fans specifically use the brushless DC motor, that is, the synchronous DC motor. DC motors require less electrical energy and help to minimize power consumption up to 70%.
