A radial stator includes a stator core, and the stator core includes a stator outer ring. M magnetic poles are arranged on an inner circumferential wall of the stator outer ring, and are evenly distributed along the inner circumferential wall of the stator outer ring. The M magnetic poles include Mmagnetic poles arranged along the inner circumferential wall of the stator outer ring and Mmagnetic poles arranged along the inner circumferential wall of the stator outer ring; M≥2, M≥1, and M≤1; the Mmagnetic poles and the Mmagnetic poles are arranged on two sides of the stator outer ring with respect to a radial direction thereof, respectively; each of the Mmagnetic poles is provided with a first winding; and each of the Mmagnetic poles is provided with a second winding; and a coil turn Nof the first winding is greater or less than a coil turn Nof the second winding.

Radial stator, magnetic levitation bearing, installation method, and motor

Disclosed are a magnetic bearing, a compressor and an air conditioner. The magnetic bearing includes a radial stator, wherein the radial stator has a plurality of stator teeth extending inwardly in a radial direction thereof; two axial stators are arranged on two axial sides of the stator teeth, respectively; and radial control coils are wound on the stator teeth, each radial control coil being located outside an area of the stator teeth covered oppositely by the two axial stators. The magnetic bearing, the compressor and the air conditioner can effectively reduce the degree of coupling between a radial electromagnetic control magnetic circuit and an axial electromagnetic control magnetic circuit, and reduce the control difficulty of the magnetic bearing.

Magnetic bearing, compressor and air conditioner

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.

Bearing stator, compressor and conditioner

Magnetic levitation bearing structure includes a cylinder body, a rotating shaft, a motor stator, a motor rotor, an axial bearing, a radial bearing and a displacement sensing device; the displacement sensing device, the axial bearing stator, and the radial bearing stator are directly fixed on an inner wall of the cylinder body.
