YX, YXKS, YXKK collection of medium and large higher-efficiency substantial-voltage cage three-phase asynchronous motors have a complete of forty center heights from H90 to H1250. Our company has adopted present day superior evaluation technology, blended with our firm’s several years of encounter in creating and producing motors. Determine and enhance the style of a variety of losses, wind resistance of every single wind route, and toughness of each ingredient. The use of large-top quality components and scientific processing technological innovation in the manufacturing helps make the series motors have the advantages of higher efficiency, reduced sound, lower vibration, higher reliability and practical set up and routine maintenance.
The effectiveness indicators of this sequence of products comply with the rules of the Ministry of Finance and the Nationwide CZPT and Reform Commission on the “Implementation Principles for the Promotion of CZPT in Universities and Schools for CZPT-saving CZPT Benefiting Projects”.
This sequence of motors can be utilized to drive different basic machinery this sort of as followers, pumps, compressors and other mechanical products, and are extensively utilised in electrical electricity, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, technical qualities and construction variety
4.one This collection of motors undertake a box structure, the frame is welded by metal plates into a box sort, light bodyweight, great rigidity, the prime of the motor is geared up with a protective top cover or cooler, which is handy for motor warmth dissipation, set up and maintenance.
4.2 The stator is made of substantial-good quality low-reduction silicon steel sheets laminated in sections to make sure the good quality of the iron main, so as to minimize iron main reduction and improve effectiveness. The stator winding is produced of F-class insulating content, which has robust insulation stand up to voltage and anti-corona capability. The winding ends are reliably set and tied, and vacuum pressure impregnation solvent-cost-free paint method (VPI) is utilized, so the motor’s insulation efficiency Exceptional and dependable, high mechanical strength, strong humidity resistance and long support daily life.
4.3 Our company styles a supporter dimensions in the identical middle, higher and the exact same pole amount in accordance to one-two energy data files, each supporter calculates the air inlet and outlet angles in element, and utilizes Ansys to analyze the partial pressure air quantity of every segment of the air duct, and design and style a realistic air duct The distribution and variety of air ducts strictly management the wind friction of the motor.
four.4 The use of copper row rotors can properly minimize extra stray losses and lessen rotor bar losses.
4.five By way of the German LDW motor large-power and high-effectiveness motor technological innovation transformation function, the slot-piece optimized construction is adopted, the air path is optimized, and the general wind resistance of the motor is decreased to lessen the total wind path decline.
four.six The bearing adopts two kinds of rolling bearing and sliding bearing. It is determined by the energy and pace of the motor. Its protection stage is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-stop oil injection and drainage unit, which is effortless for consumers to use and preserve.
four.7 The main junction box is positioned on the right side of the motor (considered from the extension conclude of the primary shaft), or it can be positioned on the left aspect according to user demands. Independent grounding terminals are offered within and outdoors the junction box.
4.8 According to person demands, temperature measuring gadgets can be added to essential elements these kinds of as stator windings and bearings to facilitate on-website observation and remote monitoring to make sure protected and trustworthy procedure of the motor.
