YKK,6KV high-voltage three-phase asynchronous motors have good performance such as efficiency, energy conservation, lower noise, slight vibration, reliable operation, convenient installation and maintenance. They are suitable for driving all kinds of equipments. If the motors are to be used to drive blowers, cool mills and steel mills and hoists, relevant technical information should be provided when placing an order based on which special design consideration will be given to the motors so as to ensure motor reliable operation. Mounting dimension and electric property index comply with IMB3 standard. Protection degree is IP54. Cooling way is IC611.Rated frequency is 50HZ,rated voltage is 6KV. Three different step motors of high pressure of YKK series 10KV are taken in order to seal emptily --Cage type rotor asynchronous motor of empty cooling. The grade of shelter of this motor is IP44 or IP54, the cooling method is IC611. This serial motors install the form as IM3. The electrical machinery adopts the box structure, light, rigidity is good. The stator adopts F grade insulatingly, VPI vacuum pressure soaks the craft of painting, globality is good, dependability is high. The quota is the continuous quota based on work system (S1 ) in succession , the specified frequency of the motor is 50Hz, the specified voltage is 10KV. Serial motor this have high-efficient , energy-conservation , with low noises , light , reliable is it maintain advantage such as being convenient to installing performance. This serial motors can be made and driven the using of various kinds of all kinds of machinery. If ventilator , compressor , water pump , breaker , cut the lathe and other equipment, suitable for colliery's , mechanical industry , power plant's and various kinds of industry and mining using as motive power.
