Embodiment 1
[0027] The preferred embodiment discloses a motor rotor. Such as Figure 1 to Figure 4 As shown, the motor rotor includes an iron core 1, a squirrel cage 2, and a permanent magnet 3. Among them, the permanent magnet 3 has a plate-shaped structure, and at least a part of the area on the permanent magnet 3 is bent toward the vertical direction of the plane to which the permanent magnet 3 belongs. The side wall column 21 of the squirrel cage 2 is inclined with respect to the bottom surface, and a chute 22 is formed between the side wall column 21; the inclination angle of the side wall column 21 matches the bending angle of the permanent magnet 3. The iron core 1 is provided with a slot 11 which is inclined with respect to the bottom surface; the inclination angle of the slot 11 is adapted to the bending angle of the permanent magnet 3.
[0028] After installation, the iron core 1, the squirrel cage 2 and the permanent magnet 3 are all spirally stretched from the bottom surface of...
Embodiment 2
[0031] The preferred embodiment discloses a self-starting synchronous motor including a stator, and the motor is provided with a rotor as described in the first preferred embodiment. The side wall columns of the squirrel cage are inclined with respect to the bottom surface, and a slanted slot is formed between the side wall columns, and the span of the slanted slot is a stator tooth width, which increases the starting ability of the motor and reduces the influence of harmonics.
