Default Ceiling fans: AC vs DC

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.
