1、 This range of motors conform to the relevant IEC stan dards and GB755 Rotating Electrical Machines Ratings and Performances General Y YKS and YKK ranges of high voltage three phase induction motors are optimum series products which are de signed and manufactured by our company using advanced tech n
2、ique 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 e
3、nergy 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 crushe
4、rs 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 chemi cal industries as well as the power plant etc If the motors are used to drive t
5、he 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 techni cal agreement should be signed which is taken as a basis of special design of motors thus ensuring the motor to operate reliably The
6、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
7、mounted construction IMB3 Y is a basic range of motors YKS and YKK ranges are series products derived according to different methods of cool ing and degrees of protection The features of YKS and YKK ranges of products are shown in the table 1 The motors are of box section construction the frame is w
8、elded into box section using steel plate and hence the weight of motors is light and rigidity is good Two sides and top of the frame are all provided with the windows which on the one hand is convenient to maintain and take care of motors and on the other hand can mount different coolers on the top
9、of frame thus being capable of deriving the motors with different methods of cooling and different degrees of protection The motor has a laminated core which is first compressed and secured before it is fitted into the frame and then pressed into the machined frame the motors have good insulating pe
