The YRKK series 6KV and 10KV three-phase asynchronous motors are closed rotor three-phase asynchronous motors, and their power levels and installation dimensions conform to the International Electrotechnical Commission (IEC) standard. The motor has the advantages of high efficiency, energy saving, low noise, small vibration, light weight, reliable performance, convenient installation and maintenance and so on. The motor can provide larger starting torque under the small starting current, and the feed line capacity is not enough to start the squirrel cage rotor motor. The starting time is longer and the starting is more frequent. It needs a small range of speed regulation and other occasions. Such as dragging, rolling mill, wire drawing machine and so on. The motor structure and installation type is IMB3, rated as continuous S1 based on continuous operation, the rated frequency of the motor is 50HZ, the rated voltage is 6KV, 10KV, and other voltage levels or special requirements can be agreed with the users when ordering.
