Novel two-stage non-contact nutating deceleration motor and working method thereof

The invention relates to a novel two-stage non-contact nutating deceleration motor and a working method thereof. The motor comprises a box body, an output shaft passing through the box body, and an output cone wheel disc and a two-stage nutating disc which are sleeved on the output shaft, wherein the two-stage nutating disc comprises an upper cone wheel disc and a lower cone wheel disc, the uppercone wheel disc is connected with the output shaft via a joint bearing, a plurality of permanent magnets A having staggered and opposite magnetic poles are uniformly distributed in the radial direction of the upper cone wheel disc, a plurality of permanent magnets B having staggered and opposite magnetic poles are uniformly distributed in the circumferential direction of the lower cone wheel disc,and an iron ring is arranged at the lower end of the lower cone wheel disc; a plurality of permanent magnets C having staggered and opposite magnetic poles and magnetically coupled with the permanentmagnets B are uniformly di
