Problems solved by technology
[0003] 1. The magnetic flux path is long and the iron loss is large; 2. Since the force on the rotor pole contains a radial component, the vibration and noise during operation are relatively large. It is an even number, which makes the design not flexible enough; 3. The rotor poles are connected by a yoke, and the rotor is heavy

The invention relates to a stator pole and rotor pole structure of a switched reluctance motor. The stator pole and rotor pole structure comprises a stator pole core, a stator pole coil, a rotor pole and a rotating shaft, wherein the stator pole and rotor pole structure is characterized in that the stator pole core is a grooved core, which comprises a beam and salient poles and has an integral structure; the salient poles are symmetrically connected to two ends of the beam; a stator pole coil is wound on the beam of the stator pole core; the stator pole core and the stator pole coil form a stator pole; the axial end surface of the rotor pole is a sector surface; a rotor pole body is fixed to a rotating shaft through a connector; the rotor pole can rotate to a groove of the stator pole core along with the rotating shaft; and a magnetic loop formed after the stator pole coil is electrified is a rectangular loop. The stator pole and rotor pole structure has the advantages that the magnetic flux path is shortened; the weight of rotors is reduced; the rotor pole is not stressed in the radial direction; vibration and noise are reduced; and meanwhile, by the manufactured motor, the numbers of the rotor poles and the stator poles can be flexibly designed.
Description
technical field [0001] The invention relates to a stator pole and rotor pole structure of a switched reluctance motor, belonging to the technical field of switched reluctance motors. Background technique [0002] The existing switched reluctance motor (SRD) has the advantages of simple and firm structure, reliable circuit, large starting torque, low starting current, wide speed range and high system reliability, but it also has the following disadvantages: [0003] 1. The magnetic flux path is long and the iron loss is large; 2. Since the force on the rotor pole contains a radial component, the vibration and noise during operation are relatively large. is an even number, which makes the design inflexible; 3. The rotor poles are connected by a yoke, and the rotor is heavy. Contents of the invention [0004] The purpose of the present invention is to provide a magnetic circuit design in which the rotor poles are embedded in the stator pole grooves, which can shorten the mag...
