  • Patent number: 11855519
    Abstract: The present disclosure provides a magnetic suspension bearing stator, a compressor and an air conditioner. The bearing stator includes a frame, a bearing iron core and an axial winding, the frame is provided with an accommodation recess used to position the axial winding. A position-limiting portion is disposed in the accommodation recess, and the position-limiting portion is used to keep the axial winding in the accommodation recess. The frame is provided with a first positioning portion for connecting with the bearing iron core on the outer wall surfaces of both sides of the accommodation recess. The frame is not easy to come out from the bearing core, and the axial winding is not easy to come out from the frame, so that the relative position between the axial winding and the bearing iron core is fixed.
