Embodiment Construction
[0017] A bearingless switched reluctance motor proposed by the present invention will be further described below in conjunction with the accompanying drawings.
[0018] like figure 1 Shown is a schematic structural diagram of a bearingless switched reluctance motor embodiment 1 of the present invention, which is a three-phase 12 / 8-pole bearingless switched reluctance motor, wherein 1 is the stator yoke, 2 is the rotor, and 3 is the Torque winding, 4 is a suspension winding. The stator yoke protrudes 4 suspension stator teeth, and each suspension stator tooth respectively protrudes 3 torque stator teeth; each torque stator tooth is wound with a torque winding, and each suspension stator tooth is wound with a suspension stator tooth respectively. Windings; the torque windings on the 4 opposite teeth are connected in series to form a phase, and the 4 suspension windings form a single set of windings, and the current of each suspension winding is independently controlled. in i ...
