YX, YXKS, YXKK collection of medium and large high-effectiveness large-voltage cage three-stage asynchronous motors have a total of forty center heights from H90 to H1250. Our organization has adopted present day innovative investigation technological innovation, combined with our firm’s a long time of knowledge in developing and production motors. Determine and improve the design and style of a variety of losses, wind resistance of every wind path, and toughness of each ingredient. The use of high-high quality components and scientific processing engineering in the production tends to make the collection motors have the positive aspects of large performance, low sound, reduced vibration, higher dependability and practical installation and maintenance.
The effectiveness indicators of this sequence of merchandise comply with the restrictions of the Ministry of Finance and the National CZPT and Reform Fee on the “Implementation Principles for the Marketing of Motors in Universities and Schools for Power-saving Products Benefiting Tasks”.
This series of motors can be used to generate a variety of standard equipment this kind of as followers, pumps, compressors and other mechanical tools, and are extensively utilised in electric energy, machinery, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, technological attributes and composition kind
four.1 This collection of motors adopt a box framework, the frame is welded by steel plates into a box variety, light fat, great rigidity, the prime of the motor is geared up with a protective leading go over or cooler, which is handy for motor heat dissipation, installation and routine maintenance.
4.2 The stator is produced of large-quality minimal-decline silicon steel sheets laminated in sections to ensure the top quality of the iron main, so as to decrease iron main decline and boost efficiency. The stator winding is produced of F-course insulating materials, which has powerful insulation face up to voltage and anti-corona capacity. The winding ends are reliably fixed and tied, and vacuum strain impregnation solvent-cost-free paint process (VPI) is utilised, so the motor’s insulation functionality Superb and reliable, high mechanical power, robust humidity resistance and prolonged services existence.
4.three Our business styles a fan dimension in the same middle, substantial and the exact same pole variety according to one-two energy information, every enthusiast calculates the air inlet and outlet angles in detail, and uses Ansys to evaluate the partial pressure air quantity of every single segment of the air duct, and design a reasonable air duct The distribution and amount of air ducts strictly handle the wind friction of the motor.
4.four The use of copper row rotors can successfully reduce additional stray losses and lessen rotor bar losses.
four.5 Via the German LDW motor high-electricity and substantial-efficiency motor technological innovation transformation work, the slot-piece optimized construction is adopted, the air path is optimized, and the general wind resistance of the motor is lowered to decrease the all round wind path reduction.
four.6 The bearing adopts two varieties of rolling bearing and sliding bearing. It is determined by the power and velocity of the motor. Its safety degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-end oil injection and drainage device, which is effortless for consumers to use and sustain.
four.7 The major junction box is positioned on the correct side of the motor (viewed from the extension stop of the principal shaft), or it can be put on the still left facet in accordance to user demands. Independent grounding terminals are offered within and outside the junction box.
four.8 In accordance to person specifications, temperature measuring products can be added to crucial components these kinds of as stator windings and bearings to facilitate on-website observation and distant monitoring to make certain safe and reliable operation of the motor.
five. Circumstances of use
5.1 Ambient air temperature: -25ºC~50ºC
five.two Altitude: no more than one thousand m
5.3 Rated frequency: 50Hz, allowable frequency deviation ±1%
5.4 For the duration of voltage procedure, the allowable voltage deviation is ±5%. (It can run at ±10% underneath the situation of 7.three in GB 755)
