Embodiment
Below in conjunction with accompanying drawing and example the utility model is further described.
As shown in Figures 1 to 4, a kind of single-phase self-starting permanent magnet machine rotor of the utility model, it comprises rotor core 1, magnet steel groove 4 and is arranged at magnet steel (figure does not show) in the magnet steel groove 4.Wherein, this rotor core 1 includes branch rotor core 11 and divides rotor core 12, be respectively equipped with magnet steel groove 41,42 on this minute rotor core 11,12, the center that this magnet steel groove 42 is arranged at this rotor core 11 is an axle, magnet steel groove 41 forward rotated on 0 ° to 30 ° the position, reach and make the back emf waveform sineization (as shown in Figure 4) of self-starting magneto, the high order harmonic component loss when having reduced the operation of self-starting magneto, thus improve the efficient of self-starting magneto.
For the ease of make up this minute rotor core 11 with divide rotor core 12, this minute rotor core 11 and this minute rotor core 12 on be respectively equipped with a plurality of self- clinching points 31,32, by the cooperation of sub-self- clinching point 31,32, with this minute rotor core 11 and this minute rotor core 12 be combined into this rotor core.Preferably, this self- clinching point 31,32 can be salient point, the concave point to cooperatively interacting, or other combinations that are used for fixing arbitrarily.
Further, this minute, rotor core 11,12 peripheral inner edge was provided with a plurality of cast aluminium grooves 21,22, this minute, rotor core 11,12 combination backs formed this rotor core 1, and these a plurality of cast aluminium grooves 21,22 also overlap and form cast aluminium groove 2, and this cast aluminium groove 2 is used for cast aluminium (figure does not show).
As shown in Figure 5, the manufacture method of single-phase self-starting permanent magnet machine rotor of the present utility model, it is example that present embodiment is two with the number of minute rotor core, it includes:
Step (one) 100: punching out has minute rotor core 11 of cast aluminium groove 21, magnet steel groove 41 and self-clinching point 31;
Step (two) 200: adjust the magnet steel groove drift position of (figure does not show), the magnet steel groove 42 of branch rotor core 12 and the magnet steel groove 41 that divides rotor core 11 are shifted to install according to same direction;
Step (three) 300: be respectively charged into magnet in the magnet steel groove of each branch rotor core at this;
Step (four) 400: be combined as this rotor core 1 by name a person for a particular job each minute rotor core of this self-clinching;
