Abstract
A rotation device with magnetic force is disclosed, comprising a rotor which has and a stator. The rotor is provided with a plurality of magnetic elements containing permanent magnets. The plurality of magnetic elements are disposed along the circumferential direction of the rotating shaft to form a wheel-shaped ring, and each magnetic element is provided with two magnetic poles. The stator is provided with a plurality of magnetically isolated electromagnets coaxially arranged. The electromagnets form a wheel-shaped ring around the rotating shaft, and each electromagnet is provided with paired poles. The wheel-shaped ring of the stator is at least partly surrounded by the wheel-shaped ring of the rotor, so that each pole of the paired poles of the electromagnets of the stator corresponds to one magnetic pole of the two magnetic poles of the magnetic elements of the rotor respectively. Two axial component air gaps are provided between the rotor and the stator. One of the abovementioned two axial component air gaps and two radial component air gaps are provided between one of the paired poles of the electromagnets of the stator and one corresponding magnetic pole of the two magnetic poles of the magnetic elements of the rotor.
