Abstract
The invention discloses a switched reluctance motor structure capable of lowering vibration noise. The switched reluctance motor structure comprises a stator and a fixing device, wherein the stator consists of a plurality of H-shaped silicon steel sheets of different models; the H-shaped silicon steel sheets are successively laminated according to a descending order of the models to form a stator; the stator is wound with a coil; the fixing device comprises a central shaft and six isolation bars; the stator wound with the coil is installed among the isolation bars of the fixing device; the surface of each H-shaped silicon steel sheet is provided with a damp-proof layer; a rotor is provided with a plurality of rotor poles; and each rotor pole is provided with a triangular notch. Through the design of a stator iron core structure, the vibration noise is greatly lowered fundamentally when the motor works through the lamination of the H-shaped silicon steel sheets and the combination of the rotor with the triangular notches. The switched reluctance motor structure has the advantages of being simple, simple in production technology and low in manufacture cost, can do work on both surfaces, improves efficiency by one time, has a damp-proof function and can not get rusty.
