    They all operate on slightly different principles.

    One ting is for certain, a rotating magnetic field causes the armature of the fan to rotate.

    See: Three phase motor, Induction motor, PSC motor, ECM motor.

    You wire it up, and then you turn it on. That's how mine work.

    Oh, and some plug in.
