Quick Answer: What type of motor is used in exhaust fan?

Exhaust fan motors usually have single phase induction motors, like that of ceiling fans. They are designed according to the functions they need to serve. Most small exhaust fans use this standard motor, that is, the single phase motor.

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 motor is used in fan AC or DC?

Ceiling fan electric motors run on either Alternating Current (AC) or Direct Current (DC). The difference between them is that AC is powered by an electrical charge with reverse flow direction and DC is working with the constant flow.

Are AC or DC fans better?

DC fans are widely regarded as the most efficient type of fans. They consume significantly less power than AC fans. In fact, DC fans consume up to 70 percent less energy to produce the same output as traditional AC fan types. This means, that a 25-watt DC-driven yields the same results as 100-watt AC fan.
