YX, YXKS, YXKK series of medium and massive substantial-performance large-voltage cage a few-phase asynchronous motors have a overall of forty centre heights from H90 to H1250. Our firm has adopted modern day advanced analysis engineering, blended with our firm’s a long time of encounter in creating and producing motors. Determine and optimize the design of different losses, wind resistance of each and every wind path, and energy of each ingredient. The use of substantial-quality supplies and scientific processing engineering in the manufacturing makes the sequence motors have the benefits of high performance, low noise, minimal vibration, high trustworthiness and convenient installation and maintenance.
The performance indicators of this collection of products comply with the laws of the Ministry of Finance and the Nationwide CZPT and Reform Fee on the “Implementation Guidelines for the Advertising of Motors in Universities and Faculties for Power-saving Merchandise Benefiting Projects”.
This collection of motors can be employed to travel a variety of common machinery this kind of as fans, pumps, compressors and other mechanical gear, and are extensively utilized in electric energy, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, complex qualities and framework sort
4.one This sequence of motors undertake a box construction, the body is welded by metal plates into a box kind, light excess weight, good rigidity, the prime of the motor is geared up with a protective top cover or cooler, which is handy for motor heat dissipation, set up and servicing.
four.2 The stator is produced of higher-good quality reduced-decline silicon steel sheets laminated in sections to ensure the quality of the iron core, so as to reduce iron core decline and enhance performance. The stator winding is made of F-class insulating materials, which has powerful insulation stand up to voltage and anti-corona capacity. The winding ends are reliably fastened and tied, and vacuum force impregnation solvent-free paint approach (VPI) is utilized, so the motor’s insulation functionality Outstanding and reputable, large mechanical toughness, powerful humidity resistance and prolonged provider life.
4.3 Our business designs a admirer dimension in the same centre, large and the very same pole number in accordance to 1-2 power information, each admirer calculates the air inlet and outlet angles in detail, and uses Ansys to examine the partial force air quantity of every single section of the air duct, and design a reasonable air duct The distribution and variety of air ducts strictly management the wind friction of the motor.
four.four The use of copper row rotors can effectively lessen added stray losses and reduce rotor bar losses.
four.5 By means of the German LDW motor high-electricity and large-performance motor technological innovation transformation operate, the slot-piece optimized construction is adopted, the air route is optimized, and the overall wind resistance of the motor is lowered to decrease the total wind path decline.
4.six The bearing adopts two varieties of rolling bearing and sliding bearing. It is established by the energy and velocity of the motor. Its security degree is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-stop oil injection and drainage system, which is simple for customers to use and maintain.
four.7 The principal junction box is placed on the appropriate aspect of the motor (considered from the extension finish of the major shaft), or it can be positioned on the remaining aspect according to consumer demands. Different grounding terminals are supplied inside and exterior the junction box.
four.8 According to person requirements, temperature measuring devices can be included to important components this sort of as stator windings and bearings to aid on-site observation and distant checking to make certain protected and trustworthy procedure of the motor.
five. Conditions of use
5.1 Ambient air temperature: -25ºC~50ºC
5.2 Altitude: no more than one thousand m
5.3 Rated frequency: 50Hz, allowable frequency deviation ±1%
5.4 In the course of voltage operation, the allowable voltage deviation is ±5%. (It can run at ±10% below the problem of seven.three in GB 755)
