The slot number of sub- punching is generally 3 integral multiple, and when the power of motor is bigger than normal, its slot number can be more, typically all more than 36.
And the winding being wound in stator punching groove is completed by the way of inlaying, some problems can be so brought, such as coiling
End is higher, so that the problems such as causing to take larger motor interior space, waste copper cash, reduction motor running efficiency.
Therefore, it is necessary to provide, a kind of stator winding slot quantity is few, offline convenient motor stator punching.
Utility model content
For defect present in prior art, the utility model discloses a kind of high-power permanent magnet stator of synchronous motor
Punching, it is desirable to provide a kind of stator winding slot quantity is few, offline convenient motor stator punching.
To achieve the above objectives, the utility model is adopted the technical scheme that：
A kind of high-power permanent magnet stator of synchronous motor punching, including：Teeth portion, yoke portion, boots portion and winding slot；

The ratio of teeth portion width and yoke portion thickness is (25.5~26.5):(13.5~14.5), i.e. teeth portion width are yoke portions
1.86 ± 0.1 times of thickness；
Boots portion thickness is 1 ± 0.01mm, and the quantity of the winding slot is 18.
Preferably, the ratio of the teeth portion width and yoke portion thickness is 13：7, i.e. teeth portion width are yoke portion thickness
1.86 again.
The ratio of the stator punching external diameter and stator punching internal diameter is 1.43.
Boots portion thickness is 1mm.
Beneficial effect：
High-power permanent magnet stator of synchronous motor punching described in the utility model, using JMAG simulation-analysis softwares, profit
With the flux loss high principle of energy conversion efficiency at least, determined by finite element optimization method and optimize each crucial chi
It is very little, the energy conversion efficiency of motor can be improved so that in the case of same volume, with the electricity using multi-slot stator punching
Motivation is higher compared to power output, can improve 1-2 percentage points, and because the slot number of motor stator punching is reduced, in manufacture
When it is easily offline, winding overhang is lower.
