Abstract
The utility model provides the radial ventilating duct of a high-voltage and high-speed motor stator and the radial ventilating duct of a high-voltage and high-speed motor rotor, which comprises a stator iron core and a rotor iron core and is characterized in that both the stator iron core and the rotor iron core are of a sectional type press mounting structure respectively. The lamination thicknesses of all the sections of the stator iron core are equal to each other. The lamination thicknesses of all the sections of the rotor iron core are also equal to each other. The lamination thickness of the rotor iron core is two times the lamination thickness of the stator iron core. a ventilation slotted plate is arranged on both sides between every two sections of the stator iron core respectively. A radial ventilating duct is formed between every two ventilation slotted plates. A ventilation sheet is arranged on both sides between every two sections of the rotor iron core respectively. A radial ventilating duct is formed between every two ventilation sheets. After the press mounting process of the stator iron core and the rotor iron core, the radial ventilating ducts of both the stator iron core and the rotor iron core are of an unsymmetrical structure and are mutually staggered from each other. Due to the adoption of the unsymmetrical radial ventilating ducts of the stator iron core and the rotor iron core, both the noise and the vibration of the motor are lowered. Therefore, the noise and vibration problem of high-voltage and high-speed motors, especially bipolar motors, can be effectively solved.
