How do you run AC fan on DC?

1 Answer. Most AC fans have induction motors and as such won’t work on DC. You will most likely need an inverter, to convert from 12VDC to the AC voltage that fan requires.

What are the disadvantages of AC over DC?

The peak value of A.C. is high and it is dangerous to use so better insulation is required. It attracts a person who touches it, unlike D.C. which gives a repelling shock. An A.C. is transmitted from the surface of the conductor and hence need several strands of thin wires insulated from each other.

Why are DC motors more expensive than AC?

The rotor design is probably the most important factor in making the DC motor more expensive. If the DC motor stator has permanent magnets, that could make it more expensive or not depending on the magnet material. There are many more manufacturers making AC motors and many more AC motors used at 1000 kW.
