I am shopping for ceiling fans and I am see adds for fans that have DC motors that are rated and advertised for a lot more efficiency.
Just don't understand why a DC motor would be much more efficient that AC ?
Any help is appreciated.
Thank You.
DC motor is 30% more efficient due to the secondary magnetic field being
generated from the permanent magnets rather than copper windings.
Does that add alot of weigh to the fan motor ?
