YX, YXKS, YXKK series of medium and massive higher-effectiveness large-voltage cage three-phase asynchronous motors have a complete of forty center heights from H90 to H1250. Our company has adopted modern day innovative evaluation technology, merged with our firm’s several years of expertise in developing and production motors. Estimate and enhance the layout of a variety of losses, wind resistance of each wind path, and energy of each and every element. The use of large-good quality resources and scientific processing engineering in the producing makes the collection motors have the benefits of substantial performance, lower noise, reduced vibration, large trustworthiness and hassle-free set up and maintenance.
The performance indicators of this series of merchandise comply with the rules of the Ministry of Finance and the National CZPT and Reform Fee on the “Implementation Policies for the Advertising of Motors in Universities and Schools for Power-conserving Products Benefiting Initiatives”.
This sequence of motors can be employed to drive different general machinery this sort of as followers, pumps, compressors and other mechanical gear, and are extensively utilised in electric powered energy, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, technical traits and framework variety
four.1 This collection of motors adopt a box composition, the frame is welded by steel plates into a box type, light fat, good rigidity, the best of the motor is outfitted with a protecting prime protect or cooler, which is handy for motor warmth dissipation, installation and upkeep.
four.two The stator is created of high-top quality lower-reduction silicon steel sheets laminated in sections to make certain the quality of the iron core, so as to lessen iron main reduction and increase effectiveness. The stator winding is produced of F-course insulating substance, which has robust insulation face up to voltage and anti-corona potential. The winding finishes are reliably fixed and tied, and vacuum strain impregnation solvent-free paint procedure (VPI) is employed, so the motor’s insulation efficiency Excellent and reliable, high mechanical energy, sturdy humidity resistance and extended service existence.
4.3 Our business designs a enthusiast dimension in the very same heart, higher and the identical pole variety in accordance to 1-two power data files, each enthusiast calculates the air inlet and outlet angles in element, and utilizes Ansys to evaluate the partial pressure air quantity of each segment of the air duct, and layout a sensible air duct The distribution and amount of air ducts strictly manage the wind friction of the motor.
four.4 The use of copper row rotors can effectively reduce added stray losses and reduce rotor bar losses.
4.five Through the German LDW motor substantial-power and higher-performance motor engineering transformation function, the slot-piece optimized construction is adopted, the air route is optimized, and the general wind resistance of the motor is decreased to minimize the general wind route loss.
4.six The bearing adopts two sorts of rolling bearing and sliding bearing. It is decided by the power and speed of the motor. Its security degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-cease oil injection and drainage device, which is effortless for end users to use and keep.
4.seven The principal junction box is positioned on the correct facet of the motor (viewed from the extension stop of the principal shaft), or it can be positioned on the still left side in accordance to user specifications. Independent grounding terminals are presented inside of and outside the house the junction box.
4.8 In accordance to consumer specifications, temperature measuring units can be additional to essential parts such as stator windings and bearings to facilitate on-internet site observation and distant checking to ensure secure and reliable procedure of the motor.
