The motor comprises a DC motor 1 and an AC motor 2. The DC motor and the AC motor are connected with a control panel 4. The control panel is connected with a switch 41. The control panel is connected with wires of battery power supply and AC power supply. The AC power supply is connected with a plug 21. The control panel controls the operation of the DC motor or the AC motor so as to drive the impeller shaft. The DC motor 1 and the AC motor 2 are located at both axial sides of the impeller shaft 31.
  • The battery power supply comprises several lithium battery packs which are mounted in a battery positioning frame 12. The DC motor is a brushless motor which is connected with a brushless controller 11, and the output shaft of the brushless motor is linked with the impeller shaft 31 directly via a coupling.
