Assembling is more convenient, it is easier to industrialized production, improves efficiency of assembling and the life-span of stator core 101.
Some embodiments of the invention, axially extending length not phase of at least two tooth boot portions 300 along rotor 20
Deng.Thus, it is more convenient for the startup of monophase machine.
In some specific examples of the present invention, as shown in Figures 1 to 10, main teeth portion 200 is provided with draw-in groove 220, yoke portion
100 are installed in draw-in groove 220, so as to realize that main teeth portion 200 is with the clamp in yoke portion 100 and easy to operate, can improve connection jail
Solidity.As shown in Figure 9 and Figure 10, draw-in groove 220 is formed as the open slot of the side for being located at main teeth portion 200, thus, be more convenient into
Row assembly manipulation.
Advantageously, as shown in Figures 1 to 8, yoke portion 100 is provided with for entering to main teeth portion 200 in the circumference in yoke portion 100
The spacing stopper slot 110 of row, main teeth portion 200 is installed in stopper slot 110, relative to prevent main teeth portion 200 from occurring with yoke portion 100
Slide, further improve connection effect.Alternatively, stopper slot 110 can be located on the inner peripheral surface or outer peripheral face in yoke portion 100.
Some embodiments of the invention, the side surface towards rotor 20 of tooth boot portion 300 be formed as arcwall face and
The combination of wherein one or two in plane.In other words, tooth boot portion 300 in yoke portion 100 axially towards the table to inner side
Face includes at least one of plane and arcwall face, can be plane or arcwall face, or the combination of plane and arcwall face.Figure
11 examples of the surface towards rotor 20 for arcwall face for showing tooth boot portion 300, are thus more convenient for adjusting and rotor 20 between
Air gap, reduce magnetic field harmonics, reduce torque ripple, improve poly- magnetic effect.
Here, the arcwall face may include at least one section arc surface, and arcwall face can be one section of arc surface, or many
The arc surface of Duan Xianglian, for example, the side surface towards rotor 20 of tooth boot portion 300 combined by nonconcentric(al) multiple arc surfaces and
Into.Thus, further beneficial to each harmonic content in adjustment air gap, to optimize the noise and vibration of motor 1.
Referring to figs. 1 to shown in Fig. 5, some embodiments of the invention, at least in yoke portion 100 and tooth boot portion 300
It is individual to be insulated with main teeth portion 200 by insulation system 500, it is beneficial to the running frequency for improving motor 1, expands range of operation, drop
Low eddy-current loss.
For example, in some specific examples of the present invention, insulation system 500 is formed as isolating separator layer, yoke portion 100 with
