I. Overview
YLYLKSYLKK series large-voltage cage-type three-section asynchronous motors have 7 middle heights from H315 to H710. The firm adopts superior engineering at residence and overseas, by way of a experienced and trustworthy layout and generation technique, and combines the design and manufacture of motors by our business for a lot of many years. Encounter, calculate and enhance the style of the various losses of the motor, the wind resistance of every wind route, and the energy of each and every ingredient. The use of high-good quality resources and scientific processing technology in the manufacturing helps make the collection motors have the rewards of high performance, lower sounds, low vibration, high dependability and practical set up and servicing.
This sequence of motors can be utilized to push a variety of common machinery this kind of as water pumps, compressors and other mechanical tools, and are commonly utilised in electric powered energy, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, specialized characteristics and composition variety
four.1 This collection of motors undertake a box-variety structure. The frame is welded from metal plates into a box-sort, with strong ribs and great toughness. The

motor is equipped with a protecting protect or cooler to aid the motor’s warmth dissipation, set up and upkeep.
four.two The stator adopts an exterior push-match structure, and the stator and rotor are punched from lower-loss non-oriented chilly-rolled silicon steel sheets. The stator winding is created of F-class insulation material, which has powerful insulation face up to voltage and anti-corona potential. The winding ends are reliably fastened and tied, and vacuum stress impregnation solvent-totally free paint process (VPI) is used, so the motor’s insulation performance Superb and dependable, high mechanical strength, robust moisture resistance and long support lifestyle.
4.3 The rotor cage bar can be produced of forged aluminum or copper according to functionality parameters or user needs. Amongst them, the solid aluminum cage bar and the finish ring are integrally forged by centrifugal to make sure the mechanical power and stop the cage bar from breaking for the duration of the motor procedure the copper bar rotor is made of higher-top quality copper content, and the cage bar is welded with the finish ring by intermediate frequency welding. The welding quality is excellent. Large strength, and through the fastening method in the groove, drastically reduce the phenomenon of damaged copper bars.
four.four When the motor has no axial thrust, the bearing adopts rolling bearing, and its protection grade is IP23IP44, IP54 or IP55. The rolling bearing is equipped with non-quit oil injection and drainage system, which is straightforward for end users to use and keep. When bearing axial thrust, thrust sliding bearing can be used.
4.5 In accordance to user needs, temperature measurement devices can be added to essential components this sort of as stator windings and bearings to aid on-internet site observation and distant monitoring to make sure risk-free and reputable procedure of the motor.
five. Problems of use
