Summary:The utility model discloses a permanent magnet brushless motor for a deep-well pump, and aims to solve the problems that in the prior art, in the rotating process of a rotor, the centrifugal force generated by the rotor is gradually increased along with the increase of the rotating speed of the rotor, the rotor is easy to slightly shift after being used for a long time, the rotor is continuously abraded after being deflected, and the service life of the rotor is prolonged. And meanwhile, the motor is easy to heat after working for a long time, so that the stable working of the motor is influenced. The permanent magnet brushless motor comprises a brushless motor shell, the outer side of the brushless motor shell is fixedly connected with a mounting frame, the outer side of the mounting frame is provided with heat dissipation fins, the top of the brushless motor shell is fixedly connected with a top sealing cover, the bottom of the brushless motor shell is fixedly connected with a bottom sealing cover, an elect
