The invention discloses a double inner-cooling type high-speed induction motor with axial multi-section rotor chutes, and relates to the field of motors. The invention aims to solve the problems of large vibration and noise and serious heat generation of the existing high-speed induction motor. The rotor chutes and the intermediate connecting ring are axially arranged in a staggered manner and are mutually connected, the rotor chutes are bilaterally symmetrical by taking the intermediate connecting ring as a center, each section of the rotor chute inclines by an angle a along the outer surface of a rotor core, the extraction type axial flow fan and the press type axial flow fan with the same blade installation angle are arranged on two sides of the end ring of the rotor, the gradual change type axial ventilation holes axially penetrate through the whole rotor, the embedded heat conducting iron core in the stator slot is connected with the yoke part of the stator core and is in contact with the stator winding, the embedded heat conducting iron core in the stator slot is internally provided with an internal cooling type rectangular ventilation channel, the water jacket is positioned in the shell and the end cover, and the heat radiating fins are positioned on the surface of the end cover. The invention reduces the vibration and noise of the high-speed induction motor, enhances the cooling effect, has simple structure and is convenient to realize. |
