Embodiment Construction
[0027] The present invention will be further described below in conjunction with accompanying drawing:
[0028] Such as figure 1 , figure 2 A permanent magnet motor rotor shown includes a rotor core and a magnetic steel 3 . The magnetic steel 3 is fixed on the outer circumference of the rotor iron core, and rotor end covers 4 are fixedly connected to both ends of the rotor iron core. Specifically, both ends of the rotor core are provided with installation holes 13 for fixed connection with the rotor end cover 4, and the rotor end cover 4 is provided with installation holes 9 for fixed connection with the rotor core, and the rotor core is connected to the rotor through rivets. The end cap 4 is fixedly connected.
[0029] Further, the rotor core is formed by laminating the punched first punching sheet 1 and the second punching sheet 2 . The first punching piece 1 and the second punching piece 2 have installation holes with different apertures, and the installation holes wit...
