Abstract
The utility model discloses a rare earth permanent magnet synchronous motor preventing magnetic leakage and belongs to a rare earth permanent magnet synchronous motor. The rare earth permanent magnet motor comprises a rotating shaft and rotor punching sheets. The multiple punching sheets are superposed to become one body and are disposed on the rotating shaft. Arc through grooves are uniformly disposed in the axial direction of the rotor punching superposed sheets. Magnetic steel with arc cross section is inlaid in the through grooves. Insulating rubber layers are disposed on the arc side surfaces of the magnetic steel. Compared with a product in the prior art, the rare earth permanent magnet motor preventing magnetic leakage has characteristics of reasonable design, simple structure, low production cost, easy processing, effective prevention of magnetic leakage of magnetic steel, and increased efficiency.
