PROBLEM TO BE SOLVED: To provide an auxiliary motor for climbing a relatively short and steep slope with a feeble power as an auxiliary power for bicycle, wheel chair or the like. SOLUTION: An outside N pole permanent magnet 2 and an outside S pole permanent magnet 4 are alternately and firmly mounted on the outside of a main ring 1, while an inside N pole permanent magnet 3 and an inside S pole permanent magnet 5 are mounted in the same way on the inside of the main ring. Here, the outer periphery of the ring as a rotating part is made to be a real circle as much as possible. An outside electromagnet 10 and an inside electromagnet 11 as many as necessary are firmly embedded into two divided holders 9 and fixed therein. While, current is supplied to the electromagnet to control N and S poles of the electromagnet using a commutator 13 for switching and supplying current from a battery to each electromagnet at an excellent timing. At that time, the rotating power of the rotating part is utilized as a power to rotate the commutator. |
