High-speed magnetic levitation motor capable of accurately detecting relative positions of spindle and bearing

The utility model discloses a high-speed magnetic levitation motor capable of accurately detecting the relative positions of a spindle and a bearing, comprising a motor spindle and a magnetic levitation bearing which sleeves the motor spindle. A sensor is arranged on the magnetic levitation bearing. The motor spindle is fixedly sleeved with a high-permeability ring. The sensor points to the outer circumferential surface of the high-permeability ring. The high-speed magnetic levitation motor capable of accurately detecting the relative positions of a spindle and a bearing has the advantages of being simple in structure, accurate in detection, and safe and reliable.
