I. Overview
YLYLKSYLKK collection large-voltage cage-type three-stage asynchronous motors have seven center heights from H315 to H710. The firm adopts sophisticated engineering at residence and overseas, via a mature and dependable layout and creation method, and combines the layout and manufacture of motors by our business for numerous a long time. Knowledge, determine and improve the style of the various losses of the motor, the wind resistance of every wind route, and the power of each and every ingredient. The use of higher-quality supplies and scientific processing engineering in the manufacturing helps make the sequence motors have the advantages of high effectiveness, low noise, reduced vibration, substantial dependability and hassle-free installation and routine maintenance.
This sequence of motors can be utilised to generate different standard equipment this sort of as h2o pumps, compressors and other mechanical tools, and are extensively employed in electric electricity, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, complex characteristics and framework variety
four.1 This collection of motors undertake a box-variety structure. The body is welded from metal plates into a box-kind, with sturdy ribs and good strength. The

motor is outfitted with a protecting go over or cooler to facilitate the motor’s heat dissipation, set up and upkeep.
four.two The stator adopts an external push-fit structure, and the stator and rotor are punched from low-decline non-oriented chilly-rolled silicon metal sheets. The stator winding is made of F-class insulation substance, which has sturdy insulation endure voltage and anti-corona potential. The winding finishes are reliably mounted and tied, and vacuum pressure impregnation solvent-cost-free paint procedure (VPI) is utilised, so the motor’s insulation efficiency Excellent and trustworthy, substantial mechanical energy, sturdy dampness resistance and extended provider life.
four.3 The rotor cage bar can be created of forged aluminum or copper according to functionality parameters or user specifications. Amongst them, the solid aluminum cage bar and the conclude ring are integrally cast by centrifugal to guarantee the mechanical power and avoid the cage bar from breaking in the course of the motor operation the copper bar rotor is made of higher-quality copper content, and the cage bar is welded with the stop ring by intermediate frequency welding. The welding top quality is great. High power, and through the fastening approach in the groove, significantly minimize the phenomenon of damaged copper bars.
four.four When the motor has no axial thrust, the bearing adopts rolling bearing, and its security quality is IP23IP44, IP54 or IP55. The rolling bearing is outfitted with non-stop oil injection and drainage unit, which is effortless for customers to use and preserve. When bearing axial thrust, thrust sliding bearing can be utilized.
4.five In accordance to consumer requirements, temperature measurement units can be added to critical components this sort of as stator windings and bearings to aid on-website observation and distant checking to make certain safe and reliable operation of the motor.
