Abstract:
1. A hybrid pole bearingless switched reluctance motor (BLSRM) comprising: a stator provided with windings; and a rotor rotating about an axis when current is conducted to the windings, wherein the rotor includes a plurality of rotor poles extending radially outward, and the stator includes a plurality of stator poles extending radially inward, wherein the windings include suspending windings to generate radial force for the rotor and torque windings to generate torque, wherein the suspending windings are mutually separated from the torque windings, wherein the rotor includes ten rotor poles, and the stator includes eight stator poles, wherein the stator poles comprise four radial force stator poles which are magnetic poles for the radial force, and four torque stator poles which are magnetic poles for the torque, wherein the four radial force stator poles include two horizontal stator poles which are arranged in an α-direction representing a horizontal axis, and two vertical stator poles which are arranged in a β-direction representing a vertical axis, the two horizontal stator poles are symmetrical to each other, and the two vertical stator poles are symmetrical to each other, and wherein each of the four radial force stator poles has a pole-arc corresponding to two times a pole-arc of each of the ten rotor poles.
