I. Overview
YLYLKSYLKK series higher-voltage cage-variety a few-period asynchronous motors have seven centre heights from H315 to H710. The business adopts advanced technological innovation at residence and overseas, by way of a experienced and reliable style and generation method, and combines the design and style and manufacture of motors by our business for numerous many years. Knowledge, calculate and enhance the design of the various losses of the motor, the wind resistance of every wind route, and the power of each ingredient. The use of high-quality supplies and scientific processing technological innovation in the production tends to make the sequence motors have the positive aspects of higher effectiveness, lower sound, lower vibration, large dependability and practical installation and routine maintenance.
This sequence of motors can be used to drive various general equipment these kinds of as h2o pumps, compressors and other mechanical gear, and are widely used in electric powered electrical power, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, specialized traits and framework type
4.one This collection of motors adopt a box-variety construction. The frame is welded from steel plates into a box-kind, with sturdy ribs and good toughness. The

motor is geared up with a protecting cover or cooler to aid the motor’s heat dissipation, set up and maintenance.
four.2 The stator adopts an exterior push-in shape composition, and the stator and rotor are punched from lower-decline non-oriented chilly-rolled silicon steel sheets. The stator winding is manufactured of F-class insulation substance, which has powerful insulation endure voltage and anti-corona ability. The winding ends are reliably fastened and tied, and vacuum force impregnation solvent-free of charge paint method (VPI) is utilized, so the motor’s insulation performance Outstanding and trustworthy, high mechanical toughness, robust moisture resistance and long provider daily life.
4.three The rotor cage bar can be produced of forged aluminum or copper according to functionality parameters or consumer requirements. Between them, the cast aluminum cage bar and the finish ring are integrally forged by centrifugal to make sure the mechanical strength and avert the cage bar from breaking for the duration of the motor procedure the copper bar rotor is created of high-top quality copper content, and the cage bar is welded with the end ring by intermediate frequency welding. The welding top quality is excellent. Higher power, and via the fastening procedure in the groove, tremendously reduce the phenomenon of damaged copper bars.
4.four When the motor has no axial thrust, the bearing adopts rolling bearing, and its safety grade is IP23IP44, IP54 or IP55. The rolling bearing is outfitted with non-stop oil injection and drainage device, which is easy for users to use and preserve. When bearing axial thrust, thrust sliding bearing can be employed.
4.5 According to consumer specifications, temperature measurement gadgets can be added to essential elements this sort of as stator windings and bearings to facilitate on-website observation and distant monitoring to guarantee risk-free and dependable procedure of the motor.
