YX, YXKS, YXKK series of medium and big high-effectiveness high-voltage cage a few-period asynchronous motors have a overall of forty center heights from H90 to H1250. Our company has adopted contemporary innovative examination technological innovation, blended with our firm’s years of knowledge in planning and producing motors. Compute and enhance the design of a variety of losses, wind resistance of each wind route, and toughness of every single component. The use of higher-quality resources and scientific processing technology in the producing helps make the sequence motors have the benefits of substantial efficiency, minimal noise, reduced vibration, substantial dependability and handy installation and routine maintenance.
The effectiveness indicators of this collection of goods comply with the restrictions of the Ministry of Finance and the Nationwide CZPT and Reform Fee on the “Implementation Principles for the Marketing of Motors in Universities and Schools for Energy-conserving Items Benefiting Tasks”.
This collection of motors can be utilised to travel numerous common equipment this kind of as supporters, pumps, compressors and other mechanical gear, and are broadly utilized in electrical electrical power, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, specialized qualities and framework variety
4.1 This series of motors undertake a box structure, the frame is welded by steel plates into a box sort, light excess weight, great rigidity, the leading of the motor is geared up with a protecting prime protect or cooler, which is practical for motor warmth dissipation, installation and maintenance.
4.2 The stator is created of high-good quality low-loss silicon metal sheets laminated in sections to make certain the quality of the iron main, so as to decrease iron core reduction and boost performance. The stator winding is made of F-course insulating content, which has powerful insulation withstand voltage and anti-corona ability. The winding ends are reliably fastened and tied, and vacuum strain impregnation solvent-cost-free paint approach (VPI) is employed, so the motor’s insulation performance Exceptional and reputable, substantial mechanical strength, robust dampness resistance and long services life.
4.three Our business styles a admirer measurement in the same centre, substantial and the very same pole quantity according to 1-2 electricity information, each and every fan calculates the air inlet and outlet angles in depth, and employs Ansys to examine the partial pressure air volume of each and every segment of the air duct, and design and style a affordable air duct The distribution and number of air ducts strictly handle the wind friction of the motor.
4.4 The use of copper row rotors can properly decrease added stray losses and lessen rotor bar losses.
four.five Via the German LDW motor large-energy and higher-performance motor technologies transformation function, the slot-piece optimized composition is adopted, the air route is optimized, and the total wind resistance of the motor is lowered to lessen the general wind path decline.
four.six The bearing adopts two types of rolling bearing and sliding bearing. It is established by the power and speed of the motor. Its security degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-end oil injection and drainage unit, which is effortless for consumers to use and sustain.
four.7 The major junction box is positioned on the right facet of the motor (considered from the extension end of the primary shaft), or it can be put on the remaining facet in accordance to consumer specifications. Separate grounding terminals are offered within and outside the house the junction box.
four.8 According to consumer specifications, temperature measuring products can be extra to important components this sort of as stator windings and bearings to facilitate on-web site observation and remote checking to guarantee risk-free and dependable operation of the motor.
