         YKK series motor is our company new products instand of the old series JS JSQ.They are Lighter weight, higher efficiency, more energy-saving, lower noise, smaller vibration, higher reliability, longer service life, and easier mounting and maintenance. Suitable for ventilators, compressors, water pumps, crushers, cutting machine tools and transportation machineries, as well as other machineries, and act as a motive power machine industrial and mining establishments such as mining, machinery, petroleum, and chemical industries as well as the power plant, etc.
the motors are of box-section construction, the frame is welded into box-section using steel plate, and hence the weight of motors is light and rigidity i 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 are of motors,and,on the other hand, can mount different coolers on the top of frame, thus being capable of deriving the motors with different methods of cooling and different degrees of protection. the motors 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 performance, higher mechanical strength, higher moisture-resistance and longer service life. the squirrel-cage rotors are of both cast aluminum construction and copper bar construction. The rotors are manufactured using advanced&relible cast-aluminum and welding process, and are well balanced.therefore,the motors operate smoothly and reliably. rolling bearing or sleeve bearings are used for the motors, depending on the power and speed of motors. Degree of protection is IP*4 or IP*4. the rolling bearing are provided with grease-filling and -diaining devices without shutdown.
