our products are selling well in the American, European, South American and Asian markets. We also can layout and make non-standard products to meet customers’ particular requirements. Support & High quality controlWe offer comprehensive drawings and offer every time necessary. YX, YXKS, YXKK series of medium and large high-effectiveness higher-voltage cage a few-period asynchronous motors have a overall of forty cEPTr heights from H90 to H1250. Our firm has adopted present day advanced evaluation EPT, combined with our firm’s a long time of knowledge in designing and production motors. Calculate and enhance the design and style of a variety of losses, wind resistance of every single wind path, and power of each component. The use of higher-high quality supplies and EPT processing EPT in the production tends to make the sequence motors have the benefits of large efficiency, minimal noise, low vibration, substantial reliability and convenient set up and maintenance.
The efficiency indicators of this collection of goods comply with the rules of the Ministry of Finance and the Countrywide DeveXiHu (West Lake) Dis.Hu (West Lake) Dis.ment and Reform Commission on the quotEPTlementation Principles for the Promotion of Motors in Universities and Faculties for Vitality-conserving Items EPTenefiting Initiatives quot.
This collection of motors can be utilised to drive a variety of EPT EPTry this sort of as supporters, pumps, compressors and other mechanical products, and are extensively employed in electric powered EPT, EPTry, mining, metallurgy, petrochemical and other EPT and mining EPTrprises.

Four, technical characteristics and structure kind
4.one This sequence of motors undertake a box composition, the body is welded by steel plates into a box sort, ligEPT excess weight, excellent rigidity, the leading of the motor is geared up with a protecting leading cover or cooler, which is hassle-free for motor heat dissipation, installation and maintenance.
four.2 The stator is produced of high-good quality lower-reduction silicon metal sheets laminated in EPTs to make sure the quality of the iron core, so as to reduce iron main loss and enhance effectiveness. The stator winding is manufactured of F-course insulating material, which has sturdy insulation endure voltage and anti-corona ability. The winding ends are reliably fastened and tied, and EPT force impregnation solvent-cost-free paint approach (VPI) is used, so the motor’s insulation efficiency Exceptional and trustworthy, large mechanical power, powerful dampness resistance and EPT provider lifestyle.
four.3 Our organization types a enthusiast size in the exact same cEPTr, substantial and the identical pole number according to one-2 EPT information, every enthusiast calculates the air inlet and outlet angles in depth, and utilizes AnsEPTto assess the partial pressure air volume of each EPT of the air duct, and design and style a reasonable air duct The distribution and number of air ducts strictly control the wind friction of the motor.
four.4 The use of copper row rotors can successfully decrease further stray losses and reduce rotor bar losses.
4.five Via the German LDW motor large-EPT and higher-efficiency motor EPT transformation work, the slot-piece optimized construction is adopted, the air path is optimized, and the overall wind resistance of the motor is decreased to decrease the all round wind route decline.
four.six The bearing adopts two kinds of rolling bearing and sliding bearing. It is decided by the EPT and pace of the motor. Its protection amount is IP44, IP54 or IP55. The rolling bearing is equipped with a non-quit oil injection and drainage unit, which is effortless for customers to use and keep.
four.seven The principal junction box is positioned on the rigEPT aspect of the motor (seen from the extension stop of the major shaft), or it can be put on the still left aspect in accordance to user demands. Individual grounding terminals are supplied within and outdoors the junction box.
