In addition, multiple stator teeths 312 can limit the stator hole 314 coaxial with stator yoke 311, rotor core 21 It can be located in stator hole 314, and rotor core 21 can be coaxial with stator hole 314.Rotor core 21 is in stator hole 314 It can be around center axis thereof.Optionally, rotor core 21 can be spaced apart pre- spacing between the inner peripheral surface of stator hole 314 From so that the rotation of rotor core 21 is more smooth.

Shown in Fig. 7, each stator teeth 312 may include：Stator teeth main body 315 and stator tooth boots 316. Wherein, stator teeth main body 315 is connected with stator yoke 311, and stator teeth 312 is allow to be connected as one with stator yoke 311 Body.Stator tooth boots 316 are located at the inner end of stator teeth main body 315, on the one hand can reduce stator teeth 312 and rotor core 21 Between air-gap reluctance, improve Distribution of Magnetic Field, the stator winding 33 that stator teeth 312 on the other hand can be located at opposing connection consolidated It is fixed, prevent stator winding 33 from being loosened by the inner end of stator teeth 312, stator winding 33 is fixed relatively reliable.

In addition, the width of stator yoke 311 can be W, the width of each stator teeth main body 315 can be V.For etc. The stator core 31 of shape, i.e. mono- timings of maximum radial dimension D of stator core 31, if W：V is too small, can lead to stator teeth 312 magnetic flux density is excessively high, or even flux density saturation occurs, in 100 course of work of motor, the iron loss of stator teeth 312 Larger, the temperature liter of stator teeth 312 is excessively high.And the stator tooth socket 313 between two neighboring stator teeth 312 is too small, adjacent Two stator teeths 312 are easy to form electromagnetic circuit, and then reduce the efficiency of motor 100 apart from too short.

If W：V is excessive, the magnetic flux density of stator yoke 311 can be caused excessively high, or even flux density saturation occur, in motor In 100 courses of work, the iron loss of stator yoke 311 is larger and temperature occurs and rises excessively high phenomenon.

Therefore, in some embodiments of the utility model, the width W of stator yoke 311 and each stator teeth main body 315 width V can meet W：V=0.6-0.7, stator yoke 311 and stator teeth 312 can more reasonably distribute stator iron The magnetic flux density of core 31 keeps the Wen Sheng of motor 100 more balanced, to improve 100 service life of motor and security performance.For example, In some specific embodiments of the utility model, the ratio of the width W of stator yoke 311 and the width V of stator teeth main body 315 Value W：V can be respectively 0.6,0.63,0.65,0.68 and 0.7 etc..

In addition, as shown in Figure 7 and Figure 8, the maximum radial dimension of stator yoke 311 is D, the maximum radial of rotor core 21 Size is d.For etc. shapes stator core 31, i.e. the timing of maximum radial dimension D mono- of stator core 31, when d/D is too small, The maximum radial dimension d of rotor core 21 is too small, if 100 low speed of motor is run, for example, the rotating speed ＜ of motor 100 The load capacity of 5000rpm, rotor core 21 are too small, drive under the operating mode loaded on an equal basis, rotor too small maximum radial dimension d Iron core 21 can seriously generate heat, and influence the normal operation of motor 100, reduce by 100 efficiency of motor, in some instances it may even be possible to be damaged.

When d/D is excessive, the cogging torque of motor 100 can be caused to become larger, the rotary inertia of rotor core 21 becomes larger, if 100 high-speed cruising of motor, for example, when the rotating speed ＞ 10000rpm of motor 100, motor 100 will produce vibration, and then generate larger Noise, influence the use feeling of motor 100 performance and user.

Therefore, in some embodiments of the utility model, the maximum radial dimension D and rotor core of stator yoke 311 21 maximum radial dimension d can meet 0.4≤d/D≤0.55, can improve the power output of the rotor core 21 of motor 100, Motor 100 is more efficient, prevents rotor core 21 from generating heat, safer, and can prevent motor 100 from generating larger vibration Noise.For example, in some specific embodiments of the utility model, the maximum radial dimension D and rotor core of stator yoke 311 The ratio d/D of 21 maximum radial dimension d can be respectively 0.45,0.48,0.51 and 0.54 etc..

It should be noted that in some embodiments of the utility model, the foreign steamer of stator core 31 and rotor core 21 Exterior feature is circle, then maximum radial dimension refers to the diameter of the rounded outer profiles of stator core 31 and rotor core 21.And in this practicality In other novel embodiments, the outer profile of stator core 31 and rotor core 21 is not round, then maximum radial dimension can To be interpreted as the size of the maximum position of radial dimension for crossing axis of the outer profile of stator core 31 and rotor core 21.
