Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing:
[0025] refer to Figure 1 to Figure 3 , a skewed rotor core, which includes a rotating shaft 2, a skewed rotor core I3 and a skewed rotor core II4, the skewed rotor core I3 and the skewed rotor core II4 are formed by laminating rotor punches , where the direction of the chute of the core slot I7 of the chute rotor core I3 and the core slot II8 of the chute rotor core II4 is set symmetrically, the core slots of the chute rotor core Ⅰ3 and the chute rotor core Ⅱ4 The chute forms an inflection point 5 at the junction. In order to stack and guide, the inner hole of each rotor punch I13 of the skewed rotor core I3 is provided with a guide keyway I1, and the inner hole of each rotor punch II of the skewed rotor core II4 is also provided with a guide keyway II; The connecting keyway I11 is integrally processed after the rotor core I3 is stacked, the connecting keyway II12 is int...
