Technical scheme：To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of highly efficient permanent magnet brushless motor, including motor housing, rotor and stator, described rotor are superimposed by rotor punching
Form, described stator is formed by stacking by stator punching, described rotor punching is disposed with axis hole from inside to outside, radiate
Hole, rotor mounting hole and lobe 8, the spacing between lobe are 24.5mm, and the center of lobe is also provided with circular groove, and circular groove is a diameter of
1.5mm, described stator punching encloses be disposed with rotor hole from inside to outside, winding slot and stator mounting hole, described stator
Punching also includes Hall plate mounting groove.
Further, it is additionally provided with inwardly protruded spacer block in described axis hole.
Further, described louvre is sector structure, and louvre is rounded evenly distributed around axis hole, and quantity is 4
It is individual.
Further, described rotor mounting hole is circle, is staggered with louvre, and quantity is 4.
Further, described winding slot is trapezoidal shape, and shorter one side sets opening, and winding slot is in around rotor hole
Circular arrangement, quantity is 12.
Further, described Hall plate mounting groove quantity is 3, is arranged on three adjacent winding slots, Hall plate
Installation channel opening is trapezoid-shaped openings, and A/F is 3mm.
Beneficial effect：The utility model provide a kind of highly efficient permanent magnet brushless motor, optimize motor armature diameter and
The groove profile of motor, using Stator notching and optimization rotor pole arc coefficient and width of rebate, stator cramp groove is by original horizontal
It is changed to vertical, then reduces the influence of multipair motor magnetic circuit to the full extent, changing stator slot shoulder shape makes motor stator punching
Mould is more robust, it is designed go out motor is in hgher efficiency compared to original motor, lower temperature rise, noise and torque ripple it is minimum.
