YX, YXKS, YXKK sequence of medium and massive higher-effectiveness higher-voltage cage 3-stage asynchronous motors have a complete of forty middle heights from H90 to H1250. Our organization has adopted modern advanced investigation engineering, blended with our company’s years of encounter in developing and manufacturing motors. Compute and optimize the design and style of numerous losses, wind resistance of each wind route, and power of each and every component. The use of high-top quality materials and scientific processing technological innovation in the production tends to make the series motors have the rewards of high effectiveness, reduced sound, low vibration, higher trustworthiness and practical installation and routine maintenance.
The effectiveness indicators of this collection of items comply with the regulations of the Ministry of Finance and the Nationwide CZPT and Reform Fee on the “Implementation Policies for the Promotion of Motors in Universities and Schools for Power-preserving Merchandise Benefiting Assignments”.
This collection of motors can be employed to drive various basic equipment this kind of as fans, pumps, compressors and other mechanical tools, and are broadly used in electric powered power, machinery, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, complex traits and composition kind
four.1 This sequence of motors adopt a box composition, the frame is welded by steel plates into a box sort, light-weight weight, great rigidity, the best of the motor is equipped with a protecting top include or cooler, which is practical for motor heat dissipation, installation and upkeep.
4.two The stator is produced of high-good quality minimal-reduction silicon metal sheets laminated in sections to make certain the high quality of the iron core, so as to minimize iron core loss and enhance effectiveness. The stator winding is made of F-course insulating content, which has sturdy insulation stand up to voltage and anti-corona capacity. The winding ends are reliably set and tied, and vacuum force impregnation solvent-totally free paint approach (VPI) is utilised, so the motor’s insulation overall performance Exceptional and reliable, higher mechanical strength, strong moisture resistance and long service lifestyle.
4.three Our company patterns a enthusiast dimensions in the very same centre, substantial and the exact same pole number in accordance to 1-2 electrical power information, every single fan calculates the air inlet and outlet angles in element, and uses Ansys to evaluate the partial stress air volume of every area of the air duct, and layout a reasonable air duct The distribution and amount of air ducts strictly management the wind friction of the motor.
4.four The use of copper row rotors can effectively lessen additional stray losses and reduce rotor bar losses.
4.5 Via the German LDW motor substantial-electricity and large-effectiveness motor technological innovation transformation operate, the slot-piece optimized framework is adopted, the air path is optimized, and the overall wind resistance of the motor is decreased to reduce the overall wind route decline.
four.six The bearing adopts two types of rolling bearing and sliding bearing. It is established by the electricity and velocity of the motor. Its protection level is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-cease oil injection and drainage system, which is easy for users to use and preserve.
four.7 The principal junction box is placed on the correct aspect of the motor (considered from the extension conclude of the principal shaft), or it can be positioned on the still left facet according to person demands. Individual grounding terminals are provided inside of and outside the junction box.
4.eight According to consumer needs, temperature measuring gadgets can be added to crucial areas these kinds of as stator windings and bearings to aid on-website observation and remote checking to guarantee secure and dependable procedure of the motor.
