rated voltage: 6kv rated power: from 710kw to 2500kw these motors adopted advanced technical result of the motor industry in recent years more, therefore the configuration is more reasonable, and the craft is more advanced, the motors are with features of high efficiency and power factor, low noise and vibration, reliable performance and convenience for mounting and maintaining. these motors have the following characteristics: large stopping torque, high thermo capacity, etc. the protection class of the out case is ip23, the poles nos. are 10 poles, 12 poles, 14 poles and 16 poles. we can also make motors with other poles, voltage, frequency, and protection class. the base of yl series large-scale vertical type three-phase asynchronous motors is a square shape, which is welded by steel plate, the weight is light, the rigidity is good. the windings of the stator are class f insulation, and there are reliable fastness and colligation at each end of the windings. the stator windings are treated with vacuum pressure impregnation (vpi) technology. therefore the motor has excellent insulation, strong mechanical and fine moisture protection. the rotor adopts single or double squirrel cage copper bar rotor configuration. whatever configuration rotor you adopted, the configuration and manufacture craft of the rotor can ensure the reliable operation of the motor. the thrust bearing is located on the top of the motor, according to the value of the withstanding axial load, the bearing structure is designed to spherical thrust roller bearing or plan thrust bearing. the bottom bearing is radial ball bearing or cylindrical roller bearing. the cooling method is natural ventilation cooling or water-air cooling. yl series large-scale vertical type three-phase asynchronous motor are used to drive varies types of water pump equipments.
