[0016] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] Such as figure 1 The structure diagram of the present invention shown is a dual-winding bearingless switched reluctance motor (prescribed counterclockwise as the positive direction of rotation), including a stator with 12 tooth poles and a rotor with 4 tooth poles. There is no winding on the rotor. The stator teeth are all wound with a main winding and an auxiliary winding. The stator teeth of the same phase are separated by two stator teeth of other phases. The main windings of the stator teeth of the same phase are connected in series. The auxiliary windings on each stator tooth The winding and the auxiliary winding on the stator tooth pole diametrically opposite to it are connected in reverse series. The tooth pole of each rotor is wider than the stator tooth pole by α, α ≥30°, so that each phase inductance has a maximum inductance of ...
