Example Embodiment
[0010] The double salient pole double squirrel cage outer rotor structure proposed by the present invention is as follows figure 1 As shown, it is composed of an outer rotor body 1, an outer squirrel cage bar 2, an inner squirrel cage bar 3, and an end ring 4.
[0011] The structure of the outer rotor body 1 is as image 3 As shown, it has a cylindrical shape with an inner and outer double salient pole structure, which is made of laminated silicon steel sheets 8 laminated. The outer rotor body 1 is punched with two sets of slots, which are an outer slot group 6 and an inner slot group 7, respectively. Both sets of slots are composed of multiple through holes evenly distributed along the circumferential direction. The through hole of the outer slot group 6 is close to the outer circumference 9 of the yoke portion of the outer salient pole 11 in the radial direction, and is located at the tangential middle position of the two adjacent salient poles on the outer salient pole 11 in th...
