摘要:
A magnetic gear comprises a first permanent magnet field having a plurality of permanent magnet magnetic poles, a second permanent magnet field having a plurality of permanent magnet magnetic poles, number of poles of which magnet is different from that of the first permanent magnet field, and a modulating magnetic pole arranged between the first permanent magnet field and the second permanent magnet field and having a plurality of pole pieces to modulate the number of poles of the first and second permanent magnet fields. Non-magnetic bars are provided between the plurality of pole pieces. One ends of the non-magnetic bars are fixed to a first non-magnetic end holding member and the other ends of the non-magnetic bars are electrically insulated from and fixed to a second non-magnetic end holding member.
