ABSTRACT:
An electric machinery provided with a PM magnetic pole wrapped by conduction winding excited magnetic poles is related to an innovative design of having a PM magnetic pole wrapped by individual magnetic poles of conduction winding excited so to prevent the PM magnetic pole from falling off due to vibration and to prevent from weakening magnetic force by inverse excitation when the electric machinery is running.
