Electric AC Motor

Electric AC Motor

YX, YXKS, YXKK collection of medium and huge high-effectiveness higher-voltage cage 3-section asynchronous motors have a complete of forty centre heights from H90 to H1250. Our business has adopted present day advanced examination engineering, mixed with our company’s a long time of experience in designing and manufacturing motors. Estimate and optimize the layout of numerous losses, wind resistance of each and every wind route, and toughness of every ingredient. The use of large-high quality components and scientific processing technology in the production makes the collection motors have the advantages of higher performance, low sounds, lower vibration, substantial trustworthiness and handy installation and maintenance.
The efficiency indicators of this collection of items comply with the restrictions of the Ministry of Finance and the National CZPT and Reform Fee on the “Implementation Rules for the Advertising of CZPT in Universities and Colleges for CZPT-saving CZPT Benefiting Tasks”.
This series of motors can be utilized to travel numerous basic equipment such as enthusiasts, pumps, compressors and other mechanical equipment, and are widely used in electrical energy, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, technological qualities and composition kind
4.one This series of motors adopt a box structure, the body is welded by metal plates into a box kind, light bodyweight, great rigidity, the top of the motor is outfitted with a protecting best cover or cooler, which is hassle-free for motor heat dissipation, installation and routine maintenance.
4.2 The stator is manufactured of substantial-good quality minimal-reduction silicon metal sheets laminated in sections to guarantee the good quality of the iron core, so as to lessen iron main loss and enhance performance. The stator winding is manufactured of F-course insulating content, which has robust insulation face up to voltage and anti-corona capacity. The winding finishes are reliably set and tied, and vacuum pressure impregnation solvent-cost-free paint process (VPI) is utilised, so the motor’s insulation functionality Excellent and reliable, large mechanical toughness, powerful humidity resistance and long provider life.
four.three Our firm patterns a enthusiast size in the identical centre, higher and the identical pole quantity in accordance to one-2 electricity data files, each and every fan calculates the air inlet and outlet angles in detail, and uses Ansys to examine the partial strain air volume of every single part of the air duct, and style a realistic air duct The distribution and number of air ducts strictly handle the wind friction of the motor.
four.four The use of copper row rotors can properly reduce further stray losses and reduce rotor bar losses.
four.5 Via the German LDW motor higher-energy and higher-efficiency motor engineering transformation operate, the slot-piece optimized composition is adopted, the air path is optimized, and the all round wind resistance of the motor is reduced to reduce the all round wind route decline.
four.six The bearing adopts two kinds of rolling bearing and sliding bearing. It is determined by the electrical power and pace of the motor. Its safety degree is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-cease oil injection and drainage system, which is straightforward for customers to use and sustain.
four.7 The main junction box is put on the right side of the motor (seen from the extension stop of the primary shaft), or it can be put on the still left facet in accordance to user demands. Individual grounding terminals are provided within and outside the junction box.
4.8 According to person specifications, temperature measuring units can be added to essential elements this sort of as stator windings and bearings to aid on-website observation and distant monitoring to guarantee protected and reputable procedure of the motor.
five. Circumstances of use
five.one Ambient air temperature: -25ºC~50ºC
5.2 Altitude: no a lot more than 1000 m
5.three Rated frequency: 50Hz, allowable frequency deviation ±1%
five.four During voltage procedure, the allowable voltage deviation is ±5%. (It can run at ±10% beneath the problem of seven.three in GB 755)
