Magnetic coupling control device and magnetic coupling device

A magnetic coupling control device, comprising:

• a magnetic flywheel unit comprising a flywheel mounted to an external machine and a plurality of first magnets mounted at the periphery of said flywheel and equiangularly spaced around the center of axis of said flywheel to form a first annular magnetic series, each said first magnet comprising a first magnetic pole facing toward the center of axis of said flywheel and a second magnetic pole opposite to said first magnetic pole;
• a magnetoresistive ring frame mounted to said external machine around the periphery of said flywheel and movable along the axial direction of said flywheel;
• and
• a magnetic coupling unit mounted to said external machine and located on the periphery of said flywheel, said magnetic coupling unit comprising a plate body, a rotating shaft, a plurality of second magnets and a plurality of third magnets, said plate body being rotatably mounted to said external machine and located on the periphery of said flywheel, said plate body comprising a bottom surface facing toward the second magnetic pole of each said first magnet, said rotating shaft being mounted to the center of axis of said plate body for synchronous rotation with said plate body, said second magnets and said third magnets being alternatively mounted on said plate body around said rotating shaft, the first magnetic pole of each said second magnet being disposed to face toward the second magnetic pole of one respective said first magnet, the second magnetic pole of each said third magnet being disposed to face toward the second magnetic pole of one respective said first magnet;
• wherein, the first magnetic poles of said second magnets and the second magnetic poles of said third magnets together form a second annular magnetic series, said second annular magnetic series being magnetically coupled to said first annular magnetic series.
