The rotating p-m potential energy output unit comprises rotation magnetic groups (1) (2) (3) and (4), stator core or magnet groups (29) (30) (31) and (32), fixed magnetic groups (51) (52) (53) and (54), a rotation control mechanism (91), and a power output mechanism (99). Based on same polarity repulsive, different polarity attractive of magnetic field, this invention makes electromagnetic force doing work and outputting with mechanical means, needs no any extra energy, and can be used as dynamic source for any machine and electric device. |
