NOVELTY - The permanent magnet synchronous motor rotor comprises a rotating shaft (1). The outer ring of the rotating shaft is welded with a rotor (2) and a bearing (3). The outer part of the rotor is fixedly installed with a rotor fan (4). The outer part of the rotor is provided with a radiating part. The radiating part is provided with a heat absorbing part and a radiating part. The radiating part is rotated. The radiating part is fixedly connected with the rotor fan. USE - Permanent magnet synchronous motor rotor. ADVANTAGE - The rotor fan is made of the radiating material, so that the rotor fan uses two radiating ways to radiate synchronously, and further enhances radiating effect of the heat. The radiating efficiency is improved, at the same time, the high temperature of the rotor is taken away. The cooling effect in the motor is accelerated, and the motor operation stability is reinforced. DESCRIPTION OF DRAWING(S) - The drawing shows a rotor of the present invention and a radiating part front mounting schematic diagram. Rotating shaft (1) Rotor (2) Bearing (3) Rotor fan (4)
