YX, YXKS, YXKK collection of medium and big substantial-efficiency high-voltage cage three-period asynchronous motors have a whole of forty middle heights from H90 to H1250. Our firm has adopted modern advanced analysis technologies, mixed with our firm’s years of expertise in developing and manufacturing motors. Determine and improve the layout of various losses, wind resistance of every single wind route, and power of each and every element. The use of substantial-high quality supplies and scientific processing technology in the manufacturing makes the sequence motors have the advantages of higher performance, minimal sounds, low vibration, higher trustworthiness and hassle-free set up and servicing.
The performance indicators of this collection of products comply with the laws of the Ministry of Finance and the Nationwide CZPT and Reform Commission on the “Implementation Principles for the Promotion of Motors in Universities and Faculties for Vitality-saving Merchandise Benefiting Initiatives”.
This series of motors can be employed to drive different common machinery such as followers, pumps, compressors and other mechanical products, and are broadly utilized in electric powered energy, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, specialized qualities and construction variety
4.one This series of motors undertake a box framework, the frame is welded by steel plates into a box variety, gentle excess weight, very good rigidity, the best of the motor is outfitted with a protecting leading protect or cooler, which is convenient for motor warmth dissipation, installation and servicing.
4.2 The stator is produced of substantial-top quality lower-loss silicon metal sheets laminated in sections to guarantee the good quality of the iron main, so as to decrease iron core decline and boost effectiveness. The stator winding is produced of F-course insulating material, which has strong insulation face up to voltage and anti-corona capability. The winding finishes are reliably fastened and tied, and vacuum force impregnation solvent-free paint approach (VPI) is utilized, so the motor’s insulation efficiency Excellent and dependable, large mechanical energy, robust dampness resistance and long services life.
4.three Our organization styles a admirer measurement in the identical middle, high and the identical pole amount in accordance to 1-two power information, each and every supporter calculates the air inlet and outlet angles in detail, and makes use of Ansys to analyze the partial strain air quantity of each and every section of the air duct, and design and style a reasonable air duct The distribution and variety of air ducts strictly management the wind friction of the motor.
4.4 The use of copper row rotors can efficiently reduce added stray losses and decrease rotor bar losses.
4.five Through the German LDW motor substantial-energy and large-performance motor engineering transformation operate, the slot-piece optimized framework is adopted, the air route is optimized, and the all round wind resistance of the motor is diminished to minimize the all round wind path reduction.
four.six The bearing adopts two varieties of rolling bearing and sliding bearing. It is decided by the electrical power and speed of the motor. Its security degree is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-cease oil injection and drainage system, which is straightforward for users to use and sustain.
4.7 The principal junction box is positioned on the right facet of the motor (considered from the extension finish of the main shaft), or it can be put on the still left side in accordance to user specifications. Different grounding terminals are offered within and outside the junction box.
4.eight According to user demands, temperature measuring gadgets can be added to crucial elements this kind of as stator windings and bearings to facilitate on-site observation and remote checking to make sure secure and reputable operation of the motor.
