<P>PROBLEM TO BE SOLVED: To provide a magnetic circuit control device for a double-shaft multilayer motor capable of synthetically improving motor efficiency and motor performance by making the magnetic circuit as a variable structure and controlling the magnetic circuit suited with operation condition. <P>SOLUTION: An inner rotor IR and an outer rotor OR are arranged through a stator S in concentric circle. In the double shaft multilayer motor M, separated stator teeth 41 with coils 42 of which the coils 42 are wound on the stator teeth 41 constituted by laminated steel plates is arranged with the same pitches on the circumference where the center is the motor rotating shaft. The stator S is provided with a magnetic circuit control means for controlling the outer rotor side space and the inner rotor side space of the abutting stator teeth 41, 41 of the separated stator teeth 41with the coils 42 corresponding to the operation condition. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
