Magnetic suspension motor sensor mounting structure

A magnetic suspension motor sensor mounting structure comprises a shaft sleeve, a sensor base and a bearing cover, a positioning key extending in the length direction of the shaft sleeve is arranged on the inner wall of the shaft sleeve, the outer diameter of the sensor base is matched with the diameter of an inner cavity of the shaft sleeve, and a positioning groove matched with the positioning key is formed in the circumferential side wall of the sensor base. A positioning step is arranged on the bearing cover, the sensor base is in clearance fit with the interior of an inner cavity of the shaft sleeve, circumferential positioning is formed through matching of a positioning groove and a positioning key, the bearing cover is assembled on the shaft end face of the shaft sleeve and fixed through a bolt, and the positioning step of the bearing cover is tightly pressed on the sensor base. And axial limiting is formed by matching with a magnetic bearing of the magnetic suspension motor. The utility model has the
