Embodiment Construction

[0030] see figure 1 and figure 2 , the invention consists of two double-stator motors with the same structure connected in series along the axial direction. The two double-stator motors are respectively the first double-stator motor I and the second double-stator motor II, and the first double-stator motor I and the second double-stator motor II are coaxially connected. The z direction is the axial direction of the two motors, and the x and y directions are radial directions perpendicular to each other. The outermost part of the first double-stator motor I is the first outer stator 1, and the first outer stator 1 is coaxially sleeved with the rotor 3, the first inner stator 5 and the rotating shaft 11 from the outside to the inside; the outer stator teeth of the first outer stator 1 The first torque winding 2 is wound on it, and the first suspension winding 4 is wound on the inner stator teeth of the first inner stator 5 . The outermost part of the second double-stator mot...

Abstract

The invention discloses a four-degree-of-freedom hybrid excitation starting / power generation integral bearingless switched reluctance motor. The four-degree-of-freedom hybrid excitation starting / powergeneration integral bearingless switched reluctance motor consists of two dual-stator motors with same structure in coaxial connection in the axial direction; torque windings are wound on outer stator teeth of the two dual-stator motors respectively; suspension windings are wound on inner stator teeth of the two dual-stator motors; the two dual-stator motors share the same rotor and the same rotating shaft; a circular ring-shaped permanent magnet sleeving the outside of the rotating shaft is fixedly connected between stator yoke parts of two inner stators of the two dual-stator motors, and the permanent magnet is axially magnetized. Integral operation of starting and power generation is realized, a suspension current magnetic circuit and a torque current magnetic circuit are of mutual independence without interference in the rotor, and the two motor torque windings are serially connected together, so that the application of a controller is reduced.

Description

technical field [0001] The invention belongs to the technical field of magnetic levitation, and relates to the structure of a hybrid excitation double-stator magnetic levitation switched reluctance motor. Background technique [0002] The magnetic levitation motor can be used as the core component in the flywheel battery, which not only can convert energy, but also has the function of magnetic bearing support. Flywheel energy storage uses the speed up and down of a high-speed flywheel to realize the mutual conversion between electrical energy and mechanical energy, which is a clean and pollution-free energy storage method. [0003] The traditional double-winding magnetic levitation switched reluctance motor organically combines the magnetic levitation technology and the switched reluctance motor. By adding a set of levitation windings to the stator poles of the switched reluctance motor, the original rotor electromagnetic force balance is broken. Electric current is used to...
