It states.
As shown in Figures 2 and 3, according to one embodiment of present invention, a kind of stator of motor is provided.The stator includes
Stator body 10, stator body 10 have stator teeth 11, offer auxiliary tank 20 on stator teeth 11.Auxiliary tank 20 is along stator
It is opened on the end face of stator teeth 11 to the length direction perforation of teeth portion 11, stator teeth 11 is along the radial direction side of stator body 10
To center line and the stator teeth on auxiliary tank 20 along stator body 10 radial direction center line have polar arc angle.
In the present embodiment, auxiliary tank 20 is set, can play and alleviate magnetic conduction channel during close to stator pole shoes
Generated excessive magnetic saturation.The magnetic pressure drop of 20 part of auxiliary tank is essentially identical to the extra part of magnetic saturation, Ke Yishi
Existing motor torque output is basically unchanged, the effect that iron loss is greatly reduced.
Wherein, auxiliary tank 20 of the stator teeth 11 on the center line and the stator teeth of the radial direction of stator body 10
Meet following formula along the polar arc angle that the center line of the radial direction of stator body 10 has: as 2/ 1 < 0.65 of α of α, α 3=
0.5 × α 2- δ, wherein α 1 is the polar arc angle of stator, and α 2 is the polar arc angle of stator teeth 11, and α 3 is auxiliary tank 20 along diameter

Shown in Fig. 1: for not plus auxiliary tank in the case of the magnetic line of force schematic diagram.From figure 1 it appears that the passed through stator of the stator magnetic line of force
When the pole shoe of 11 two sides of teeth portion, since magnetic conductive area is small, flux density can generate supersaturation (indicating in figure with 4 magnetic lines of force), lead to
It often can reach 2.2T or more.Iron loss increases obvious at this time, and output torque fails to get a promotion due to saturation.Such as Fig. 2 institute
Show: after increasing auxiliary tank 20, due to the presence of auxiliary tank 20, so that the magnetic line of force paths traversed magnetic resistance under the position increases
Add, flux density saturation is eased and (is indicated in figure with 3 magnetic lines of force), and after iron loss is decreased obviously, torque output is almost unchanged.
Preferably, in order to improve the performance of motor stator, the polar arc angle fluctuation angle that auxiliary tank 20 allows is set
Set range restriction are as follows: 0 δ≤1.5 <.
As shown in figure 3, the groove width of auxiliary tank 20 is Ws in order to further improve the performance of motor stator, wherein
0.5mm≤Ws≤1.5mm.The groove depth of auxiliary tank 20 is Wb, and the magnetic conduction distance of auxiliary tank 20 is Hsb, wherein Wb≤Hsb≤
2Wb.Wherein, the size of Ws according to the air gap between the stator and rotor of motor with can choose, when air gap is larger, on Ws can use
Limit value, when air gap is smaller, Ws removes limit value.Hsb should also combine stator tooth while taking into account the above required distance
The intensity requirement in portion 11.
It preferably, is synchronous magnetic resistance motor by increasing auxiliary tank and not increasing auxiliary tank emulation shown in Fig. 9 and Figure 10
Iron loss comparison and torque versus scheme, wherein the position of auxiliary tank and size scheme are as follows: δ=1.2, Ws=1.4, Hsb=1.7Wb.
By in figure as can be seen that motor iron loss decline 13%, torque output decline only 1%, motor overall performance is promoted.In high frequency
Under, the motor advantage that auxiliary tank is arranged is more obvious.
Wherein, stator teeth 11 is multiple, and multiple stator teeths 11 are evenly arranged on the inner peripheral surface of stator body 10,
Auxiliary tank 20 is offered on each stator teeth 11.This is also provided with the performance that can effectively improve motor stator.
According to another embodiment of the invention, stator teeth 11 is along the center line of the radial direction of stator body 10 and this
Auxiliary tank 20 on stator teeth meets following formula along the polar arc angle that the center line of the radial direction of stator body 10 has:
As 2/ 1 < 0.65 of α of α, α 3=0.5 × α 2- δ, Hsb=1.7Wb, wherein α 1 is the polar arc angle of stator, and α 2 is stator teeth
11 polar arc angle, α 3 are the center line radially of the center line and stator teeth 11 radially of auxiliary tank 20
Polar arc angle, δ be allow polar arc angle fluctuation angle, Wb be auxiliary tank 20 groove depth；Hsb be auxiliary tank 20 magnetic conduction away from
From.Setting can guarantee that reaching reasonable alleviates flux density saturation in this way, and reach on the smallest level of motor output torque influence.
As shown in Figures 4 to 7, in the present embodiment, in order to reach the smooth excessive of the magnetic line of force, while reducing the sword of mold
Mouth stress.The cross section of auxiliary tank 20 can be arranged to squarely, triangle, semicircle or trapezoidal.
