YX, YXKS, YXKK sequence of medium and massive high-effectiveness higher-voltage cage three-period asynchronous motors have a whole of forty centre heights from H90 to H1250. Our firm has adopted modern innovative investigation technologies, mixed with our company’s several years of encounter in designing and manufacturing motors. Determine and improve the layout of a variety of losses, wind resistance of every single wind route, and strength of every single element. The use of high-high quality supplies and scientific processing engineering in the production tends to make the sequence motors have the positive aspects of substantial efficiency, lower sound, reduced vibration, higher reliability and practical set up and routine maintenance.
The effectiveness indicators of this series of items comply with the laws of the Ministry of Finance and the Nationwide CZPT and Reform Commission on the “Implementation Guidelines for the Marketing of Motors in Universities and Faculties for Power-preserving Products Benefiting Initiatives”.
This collection of motors can be used to generate different basic machinery this kind of as supporters, pumps, compressors and other mechanical products, and are broadly employed in electric electricity, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, specialized qualities and composition variety
four.one This collection of motors undertake a box framework, the body is welded by steel plates into a box sort, light excess weight, good rigidity, the leading of the motor is outfitted with a protecting best cover or cooler, which is handy for motor heat dissipation, set up and servicing.
4.two The stator is produced of large-quality minimal-loss silicon steel sheets laminated in sections to make sure the quality of the iron main, so as to decrease iron main decline and boost performance. The stator winding is made of F-class insulating content, which has powerful insulation stand up to voltage and anti-corona potential. The winding ends are reliably fastened and tied, and vacuum force impregnation solvent-totally free paint process (VPI) is utilised, so the motor’s insulation functionality Excellent and trustworthy, higher mechanical energy, powerful humidity resistance and long provider daily life.
four.3 Our firm designs a fan size in the identical center, large and the very same pole number in accordance to 1-two electrical power data files, each and every fan calculates the air inlet and outlet angles in depth, and employs Ansys to evaluate the partial stress air quantity of every single area of the air duct, and layout a realistic air duct The distribution and number of air ducts strictly management the wind friction of the motor.
4.four The use of copper row rotors can successfully reduce extra stray losses and minimize rotor bar losses.
four.5 Via the German LDW motor high-power and high-effectiveness motor technologies transformation perform, the slot-piece optimized structure is adopted, the air path is optimized, and the general wind resistance of the motor is decreased to minimize the overall wind path decline.
four.6 The bearing adopts two kinds of rolling bearing and sliding bearing. It is identified by the electricity and speed of the motor. Its protection degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-quit oil injection and drainage unit, which is straightforward for end users to use and maintain.
4.seven The major junction box is positioned on the right aspect of the motor (viewed from the extension finish of the primary shaft), or it can be put on the left facet in accordance to user specifications. Individual grounding terminals are supplied inside and outside the junction box.
four.eight In accordance to consumer demands, temperature measuring products can be additional to important parts these kinds of as stator windings and bearings to aid on-internet site observation and distant checking to guarantee risk-free and trustworthy procedure of the motor.
