Y, YKK, and YKS ranges of high-voltage three-phase induction motors are optimum series which are designed and manufactured by our company using advanced technique at home and abroad, in combination with tens-year practical experiment of our company on production of high-voltage motors, and are renewing and generation-changing products of former JS and JSQ series high-voltage motors. They have advantages of compact construction, light weight, high efficiency, energy-saving, low noise, small vibration, high reliability, long service life, easy mounting and maintenance, etc., as compared with former JS and JSQ series products.

This range of motors are suitable for driving the general purpose machineries such as all kinds of ventilators, compressors, water pumps, crushers, cutting machine tools and transportation machineries, etc. As well as other machineries, and act as a motive power machine in all kinds of industrial and mining establishments such as mining, machinery, petroleum, and chemical industries as well as the power plant, etc. If the motors are used to drive the blower, the coal-grinder, the rolling mill, the lifting winch and the belt conveyer, the relevant technical information should be supplied when ordering, and the technical agreement should be signed, which is taken as a basis of special design of motors, thus ensuring the motor to operate reliably.

The motors are class F insulated, but thermally utilized according to class B. Rated frequency is 50Hz, rated voltage is 3Kv, 6Kv, or 10Kv, and the motors of 60Hz and other voltages can also be available on request of ordering.

The basic mounting arrangement of motors of this range is of the horizontally foot-mounted construction (IMB3). Y is a basic range of motors, YKS and YKK ranges are series products derived according to different methods of cooling and degrees of protection.

This range of motors conform to the relevant IEC standards and GB755 Rotating Electrical Machines-Ratings and Performances.
