For defect present in prior art, the purpose of this utility model is to provide a kind of motor stator punching,
Aim to provide a kind of few stator slot quantity, fluting convenience, offline convenient motor stator punching.
To achieve the above objectives, the utility model is adopted the technical scheme that：
A kind of motor stator punching, including teeth portion 1, yoke portion 2, winding slot 3, boots portion 4 and notch 5；
The external diameter of the motor stator punching and the ratio of internal diameter are (1.580 ± 0.002)：1；
The ratio of the width of teeth portion 1 and the thickness in yoke portion 2 is (6.4~6.6):(4.4~4.6), i.e. the width of teeth portion 1 is
1.44 ± 0.06 times of the thickness in yoke portion 2；
The thickness in boots portion 4 is 1.3mm ± 0.1mm；The width of notch 5 is 2.5mm ± 0.02mm；The number of the winding slot 3
Measure as 6.
Preferably, the external diameter of the stator punching and the ratio of internal diameter are 1.58：1；
The ratio of the width of the teeth portion 1 and the thickness in yoke portion 2 is 6.5:4.5, i.e. the width of teeth portion 1 is the thickness in yoke portion 2
1.44 times of degree；
The thickness in the boots portion 4 is 1.3mm；
The width of the notch 5 is 2.5mm.
Motor stator punching described in the utility model, using JMAG analysis softwares, at least can using flux loss
The principle of high conversion efficiency is measured, each critical size for determining and optimizing by finite element optimization method can improve motor
Energy conversion efficiency so that in the case of same volume, with using multi-slot stator punching motor compared with power output more
Height, can improve 2~3 percentage points, and easily fluting, offline, convenient operation during fabrication.
