YX, YXKS, YXKK collection of medium and big large-effectiveness high-voltage cage a few-section asynchronous motors have a total of forty heart heights from H90 to H1250. Our firm has adopted present day superior examination technology, blended with our company’s a long time of knowledge in planning and production motors. Determine and enhance the design and style of different losses, wind resistance of each and every wind route, and strength of every single ingredient. The use of large-good quality materials and scientific processing technology in the producing tends to make the collection motors have the rewards of substantial effectiveness, lower sound, low vibration, large reliability and convenient set up and upkeep.
The performance indicators of this sequence of merchandise comply with the rules of the Ministry of Finance and the National CZPT and Reform Fee on the “Implementation Guidelines for the Advertising of Motors in Universities and Faculties for Vitality-conserving Goods Benefiting Tasks”.
This collection of motors can be employed to travel different general equipment this sort of as fans, pumps, compressors and other mechanical gear, and are widely used in electric electrical power, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, complex qualities and structure kind
four.one This collection of motors undertake a box structure, the body is welded by metal plates into a box kind, light fat, great rigidity, the top of the motor is outfitted with a protecting best go over or cooler, which is practical for motor warmth dissipation, set up and servicing.
four.two The stator is made of higher-quality lower-decline silicon steel sheets laminated in sections to make sure the high quality of the iron core, so as to minimize iron core reduction and enhance effectiveness. The stator winding is made of F-course insulating material, which has sturdy insulation withstand voltage and anti-corona capacity. The winding ends are reliably fastened and tied, and vacuum force impregnation solvent-free paint method (VPI) is utilized, so the motor’s insulation functionality Outstanding and reliable, large mechanical power, powerful humidity resistance and prolonged support life.
four.3 Our firm designs a fan size in the same center, high and the very same pole variety according to 1-2 electricity documents, every single enthusiast calculates the air inlet and outlet angles in detail, and makes use of Ansys to assess the partial pressure air quantity of each and every part of the air duct, and design and style a sensible air duct The distribution and amount of air ducts strictly control the wind friction of the motor.
4.four The use of copper row rotors can successfully decrease added stray losses and minimize rotor bar losses.
four.five Via the German LDW motor higher-electrical power and higher-performance motor technologies transformation function, the slot-piece optimized construction is adopted, the air route is optimized, and the all round wind resistance of the motor is lowered to decrease the overall wind path loss.
four.6 The bearing adopts two varieties of rolling bearing and sliding bearing. It is established by the electrical power and velocity of the motor. Its defense level is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-end oil injection and drainage device, which is effortless for consumers to use and maintain.
four.seven The main junction box is positioned on the proper aspect of the motor (considered from the extension conclude of the principal shaft), or it can be placed on the remaining aspect in accordance to consumer specifications. Independent grounding terminals are provided inside of and exterior the junction box.
four.eight In accordance to person specifications, temperature measuring units can be additional to essential parts these kinds of as stator windings and bearings to facilitate on-web site observation and remote checking to ensure risk-free and trustworthy operation of the motor.
