Embodiment Construction
[0026] Such as Figure 1-Figure 11 As shown, the present invention is realized in this way. The rotor core 2 is formed by laminating the rotor punches 1. The outer circumference of the rotor punches 1 is evenly distributed with outer grooves 11, middle grooves 12 and inner grooves 13. The rotor punches 1 are aligned with each other. After being stacked, they are connected into the outer guide bar hole 21, the middle guide bar hole 22 and the inner guide bar hole 23 in the rotor core 2; the middle guide bar hole 22 is inserted with an inverted trapezoidal copper guide bar 3, and the outer guide bar hole 21 is cast with an outer aluminum The guide bar 41, the inner guide bar hole 23 is cast with the inner aluminum guide bar 42, the two ends of the rotor core 2 are cast with the aluminum end ring 43, and the aluminum end ring 43 has an aluminum fan blade 44 and an aluminum balance column 45; the outer aluminum guide bar 41. The inner aluminum guide bar 42, the aluminum end ring 4...
