The specific type of DC motor used in ceiling fans is a brushless DC motor (aka synchronous DC motor). A DC motor uses an internal array of magnets of opposing polarity.

Why DC motor is used in ceiling fan?

DC motor fans provide a high torque at a low speed, meaning greater airflow and less energy consumption – up to 70% less than conventional (AC) ceiling fan motors. Energy Star fans with DC motors are not only quick to start, they’re also quick to stop and accelerate.

Will a DC motor run on AC?

We already know that in a DC Series motor the field winding has very less resistance than a DC Shunt Motor as the field is connected in series with the Armature Winding. So if we give AC supply on a DC Series Motor it will run perfectly. In fact, DC Series can run on both AC and DC supply.
