YX, YXKS, YXKK sequence of medium and large higher-efficiency large-voltage cage a few-section asynchronous motors have a total of forty heart heights from H90 to H1250. Our company has adopted present day superior examination technology, merged with our firm’s a long time of knowledge in planning and producing motors. Compute and optimize the layout of different losses, wind resistance of each wind path, and power of each element. The use of substantial-good quality components and scientific processing engineering in the production makes the series motors have the advantages of large efficiency, low sounds, minimal vibration, higher dependability and hassle-free set up and routine maintenance.
The performance indicators of this collection of merchandise comply with the regulations of the Ministry of Finance and the Nationwide CZPT and Reform Commission on the “Implementation Policies for the Marketing of Motors in Universities and Schools for Power-preserving Items Benefiting Projects”.
This series of motors can be used to travel various general equipment this kind of as fans, pumps, compressors and other mechanical gear, and are extensively used in electric electrical power, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, technological qualities and framework sort
4.1 This collection of motors adopt a box framework, the body is welded by steel plates into a box kind, light-weight excess weight, excellent rigidity, the top of the motor is outfitted with a protective top go over or cooler, which is hassle-free for motor heat dissipation, set up and routine maintenance.
four.2 The stator is produced of substantial-quality low-decline silicon metal sheets laminated in sections to make sure the high quality of the iron core, so as to reduce iron main reduction and increase performance. The stator winding is created of F-class insulating content, which has sturdy insulation stand up to voltage and anti-corona capability. The winding ends are reliably set and tied, and vacuum stress impregnation solvent-free paint method (VPI) is employed, so the motor’s insulation overall performance Excellent and reputable, high mechanical energy, powerful humidity resistance and prolonged support daily life.
four.three Our firm styles a supporter measurement in the very same middle, large and the exact same pole amount according to one-2 electrical power information, each and every supporter calculates the air inlet and outlet angles in depth, and uses Ansys to evaluate the partial stress air quantity of every single area of the air duct, and style a realistic air duct The distribution and quantity of air ducts strictly management the wind friction of the motor.
four.four The use of copper row rotors can effectively decrease extra stray losses and decrease rotor bar losses.
4.5 By way of the German LDW motor substantial-power and substantial-performance motor technologies transformation operate, the slot-piece optimized composition is adopted, the air route is optimized, and the overall wind resistance of the motor is reduced to lessen the total wind path decline.
four.six The bearing adopts two types of rolling bearing and sliding bearing. It is established by the electricity and pace of the motor. Its protection stage is IP44, IP54 or IP55. The rolling bearing is geared up with a non-cease oil injection and drainage unit, which is simple for consumers to use and keep.
4.seven The major junction box is placed on the correct aspect of the motor (viewed from the extension end of the major shaft), or it can be positioned on the remaining aspect according to user specifications. Different grounding terminals are provided inside and outdoors the junction box.
four.eight According to consumer requirements, temperature measuring products can be added to crucial elements this sort of as stator windings and bearings to facilitate on-internet site observation and distant checking to make certain safe and reputable procedure of the motor.
