Introduction to YKS series motors
The YKS series 6kV (10kV) three - phase asynchronous motors (with a center height of 355 - 630) are three - phase asynchronous motors with squirrel - cage rotors. These three - phase asynchronous motors are manufactured in accordance with JB/T7593–1994 "Technical Specifications for Y Series 6kV High - Voltage Three - Phase Asynchronous Motors (Frame Sizes 355 - 630)" and JB/10446 - 2004 "Technical Specifications for Asynchronous Motors (Frame Sizes 400 - 800)". The protection class of the YKS series motors is IP44/IP54, and the cooling method is ICW81A.
This series of motors features advantages such as high efficiency, energy - saving, low noise, small vibration, light weight, reliable performance, and convenient installation and maintenance. They can be used to drive various types of machinery, such as ventilators, compressors, water pumps, crushers, cutting machine tools and other equipment. They can also serve as prime movers for coal mines, the machinery industry, power plants and various industrial and mining enterprises.
The structure and installation type of this series of motors is IMB3. The rating is based on the continuous duty system (S1). The rated frequency of the motors is 50Hz, and the rated voltages are 6kV and 10kV. Other voltage levels or special requirements can be negotiated with users when placing an order.
