Abstract:
A magnetically actuated rotary apparatus comprising:a casing; a supporting frame coupled with the casing, defining an inner space therein between the casing and the supporting frame, having a central hole; a central shaft, supported by the central hole of the supporting frame; a rotor assembly coupled with the central shaft and rotatable with the central shaft about a central axis of the central shaft, the rotor assembly comprising a plurality of fixed rotor magnets supported by a fixed rotor magnet supporting mechanism to the rotor assembly, each of the fixed rotor magnets having an inclined angle with respect to the central axis of the central shaft; an outer actuating assembly arranged around the rotor assembly, comprising a plurality of movable outer magnets spaced from each other, the movable outer magnet being formed with an inclined angle correspondingly opposite to the fixed rotor magnet mounted on the rotor assembly; and an actuating device mechanically coupled to the outer actuating assembly for moving the movable outer magnets of the outer actuating assembly toward or backward the fixed rotor magnets of the rotor assembly so as to magnetically actuate the rotor assembly to rotate.
