Problems solved by technology

[0002] When the existing permanent magnet synchronous motor is working, the interaction between the stator and the rotor will generate heat, and the sealing conditions between the stator, the rotor and the housing are very good, and the heat dissipation effect is not very ideal. If the working time is long, it will Unable to continue to work, if forced to continue to work, the motor will be burned
[0003] Chinese patent (authorized announcement number: CN205693489U) discloses a permanent magnet synchronous motor that is easy to dissipate heat. The patent uses a water inlet, a water inlet pipe, a water inlet control valve, and a water inlet hose to make water delivery convenient and water inlet control. Accurate; the water outlet, water outlet pipe, water outlet control valve, and water outlet hose are used together to facilitate water discharge; however, the water cooling method adopted in this patent still has great technical defects; it cannot effectively cool the motor completely, especially The moving shaft end of the motor cannot be cooled
