YX, YXKS, YXKK collection of medium and huge large-effectiveness large-voltage cage three-section asynchronous motors have a overall of forty centre heights from H90 to H1250. Our firm has adopted contemporary superior examination technological innovation, combined with our company’s several years of expertise in planning and manufacturing motors. Calculate and enhance the layout of numerous losses, wind resistance of each wind route, and toughness of each and every part. The use of substantial-top quality resources and scientific processing technology in the producing tends to make the series motors have the advantages of substantial performance, minimal sounds, reduced vibration, higher reliability and practical set up and maintenance.
The performance indicators of this series of items comply with the rules of the Ministry of Finance and the Nationwide CZPT and Reform Fee on the “Implementation Rules for the Advertising of Motors in Universities and Faculties for Vitality-saving Merchandise Benefiting Tasks”.
This sequence of motors can be utilized to push a variety of basic machinery such as enthusiasts, pumps, compressors and other mechanical gear, and are broadly utilised in electrical energy, machinery, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, technological attributes and structure kind
four.1 This series of motors undertake a box structure, the frame is welded by steel plates into a box sort, gentle bodyweight, excellent rigidity, the top of the motor is outfitted with a protective top cover or cooler, which is handy for motor heat dissipation, installation and upkeep.
4.2 The stator is made of large-quality reduced-reduction silicon steel sheets laminated in sections to make sure the quality of the iron main, so as to decrease iron core decline and improve efficiency. The stator winding is made of F-course insulating substance, which has sturdy insulation stand up to voltage and anti-corona capability. The winding ends are reliably mounted and tied, and vacuum pressure impregnation solvent-free paint procedure (VPI) is used, so the motor’s insulation efficiency Exceptional and dependable, substantial mechanical energy, strong humidity resistance and lengthy services life.
4.three Our business patterns a admirer dimensions in the very same heart, higher and the identical pole variety according to one-2 electrical power files, every fan calculates the air inlet and outlet angles in element, and makes use of Ansys to evaluate the partial stress air quantity of every single area of the air duct, and design a affordable air duct The distribution and amount of air ducts strictly management the wind friction of the motor.
four.four The use of copper row rotors can efficiently reduce additional stray losses and decrease rotor bar losses.
four.5 By way of the German LDW motor high-power and large-performance motor technological innovation transformation operate, the slot-piece optimized framework is adopted, the air path is optimized, and the total wind resistance of the motor is decreased to minimize the general wind route decline.
4.six The bearing adopts two sorts of rolling bearing and sliding bearing. It is determined by the electrical power and velocity of the motor. Its protection degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-quit oil injection and drainage gadget, which is easy for end users to use and sustain.
four.7 The main junction box is placed on the proper side of the motor (viewed from the extension stop of the principal shaft), or it can be positioned on the remaining aspect according to user demands. Individual grounding terminals are provided within and exterior the junction box.
4.8 According to person demands, temperature measuring units can be additional to critical elements such as stator windings and bearings to aid on-internet site observation and distant monitoring to guarantee protected and trustworthy operation of the motor.
