<P>PROBLEM TO BE SOLVED: To provide a magnetic gear capable of improving strength of a magnetic pole piece and reducing loss while keeping a torque transmission property. <P>SOLUTION: To achieve the purpose described above, a magnetic gear is provided with, for example, a first permanent magnet field having plural permanent magnet poles, a second permanent magnet field having plural permanent magnet poles whose number of poles is different from that of the first permanent magnet field, a modulation magnetic pole that has plural magnetic pole pieces between the first and second permanent magnet fields and modulates the number of poles of the first and second permanent magnet fields. A non-magnetic bar is provided between the plural magnetic pole pieces, one end of the non-magnetic bar is connected with a first non-magnetic end holding member, and the other end of the non-magnetic bar is electrically insulated from a second non-magnetic end holding member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
