| description | The invention provides an anti-demagnetization permanent magnet motor rotor, which comprises a rotating shaft, a rotor core, permanent magnet slots and permanent magnets, wherein the permanent magnet slots of which the number is equal to the number of poles of a motor are distributed on the rotor core employing the rotating shaft as the center; and the permanent magnets are arranged in the corresponding permanent magnet slots. According to the anti-demagnetization permanent magnet motor rotor, the permanent magnet slots are set to be W-shaped permanent magnet slots or V-shaped permanent magnet slots, and each segment of slot in each permanent magnet slot is set to be a trapezoidal slot, so that effective adjustment of local demagnetization working points of the permanent magnets is facilitated, improvement of the minimum demagnetization working point is facilitated and enhancement of the anti-demagnetization capacity is facilitated; the slope of two slots in the left of each permanent magnet slot and the slop |
