Description

technical field [0001] The invention relates to a motor, in particular to a magnetic levitation motor, which belongs to the technical field of magnetic levitation and motors. Background technique [0002] The traditional bearingless magnetic levitation motor stator has two structures of double winding and single winding. At present, most of the stators of magnetic levitation motors have a double-winding structure. The magnetic levitation motors laminate the windings that generate radial force in the electromagnetic bearings to the stator windings of the motor, that is, two sets of windings with a pole pair difference of 1 are embedded in the stator, respectively. Torque winding and levitation winding, two inverters feed the current of the same frequency to the two sets of windings, so that two rotating magnetic fields with different numbers of pole pairs are generated in the air gap, thereby generating torque and levitation force at the same time, so as to Realize the drivi...
