Embodiment 1:
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are please referred to, the present embodiment provides a kind of stator, stator has 1 He of stator yoke
It is multiple along the circumferentially equally distributed stator tooth 2 of stator, and with the spaced stator slot 3 of stator tooth 2, the notch of stator slot 3
Towards the axle center of stator；
Stator tooth 2 has denticle portion 21, and on the radial section of stator, two opposite sides of denticle portion 21 are formed towards fixed
The angle in sub- outside is θ, 0 ° of 10 ° of < θ <.
The size of θ influences the density of the magnetic line of force, and when θ value is smaller, the ability for changing the magnetic line of force is weaker, when θ value is excessive
When, cause stator slot 3 is opposite to reduce, influences copper olse, and then influence electric efficiency；When 0 ° 5 ° of < θ <, can effectively it adjust
Magnetic line of force density is saved, increases motor power output, reduces by six frequency multiplication electromagnetic force of motor zeroth order, reduce noise of motor.
Angle degree is the half of θ, tooth between 21 side of denticle portion and the stator center line for dividing equally the denticle portion 21
The facewidth of body portion 21 towards stator lateral ends is T5, and the facewidth of denticle portion 21 towards stator center one end is T3, and T3:T5 >
0.6, stator tooth 2 has tooth boots 22, and side of the denticle portion 21 towards stator center is arranged in tooth boots 22, and tooth boots 22 include two points
The bevel edge not connect with denticle portion 21；The angle that bevel edge and 21 side of denticle portion are formed is α, 130 ° of 150 ° of < α <；
The length of stator tooth 2 is T1, and the sum of the length of stator tooth 2 and the thickness of stator yoke 1 are T2；T1 and T2 numeric ratio model
Enclosing is 0.5 to 0.9, and the width of rebate of stator slot 3 is T4, and the width of rebate of stator slot 3 is excessive to will increase noise of motor, when T3 with
When the length ratio range of T4 is 1.45 to 1.55, noise of motor can be effectively reduced.
When the ratio of T1 and T2 is too small, stator tooth 2 is smaller, so that the effect for changing the magnetic line of force is unobvious；As T1 and T2
Ratio it is excessive when, 1 thickness of stator yoke becomes smaller, to increase motor iron loss, 130 ° of 150 ° of < α < advantageously reduce motor leakage
Magnetic improves motor power output.
As shown in connection with fig. 3, tooth boots 22 include interconnecting piece 221 and extension 222, and interconnecting piece 221 connect with denticle portion 21, prolongs
Extending portion 222 is connect with the side of interconnecting piece 221 towards stator center, on stator radial section, interconnecting piece 221 be it is trapezoidal, prolong
Extending portion 222 is rectangle.
A kind of motor, including stator former, the rotor of motor are spindle rotationally arranged in stator interior, when the motor rotates,
Stator can effectively adjust magnetic line of force density, increase motor power output, while reducing by 3 torque of motor torque ripple and stator slot, drop
Low six frequency multiplication electromagnetic force of motor zeroth order.
On the other hand, in present invention described above embodiment, as 0 ° of 5 ° of < θ <, 0.85,135 ° of 0.75 < T1:T2 <
At 145 ° of < α <, density of line of magnetic force can be effectively increased, increases motor power output, reduces by six frequency multiplication electromagnetic force of motor zeroth order, reduce
Noise of motor.
