YX, YXKS, YXKK sequence of medium and big large-performance large-voltage cage three-phase asynchronous motors have a overall of forty center heights from H90 to H1250. Our organization has adopted contemporary advanced investigation technology, combined with our firm’s several years of knowledge in developing and production motors. Compute and improve the style of different losses, wind resistance of every single wind path, and toughness of every element. The use of substantial-high quality materials and scientific processing technology in the production helps make the collection motors have the positive aspects of large efficiency, lower sound, reduced vibration, substantial dependability and convenient set up and upkeep.

The effectiveness indicators of this collection of items comply with the restrictions of the Ministry of Finance and the Countrywide CZPT and Reform Fee on the “Implementation Rules for the Promotion of Motors in Universities and Faculties for Vitality-conserving Items Benefiting Projects”.
This sequence of motors can be used to travel different general machinery this kind of as fans, pumps, compressors and other mechanical tools, and are extensively used in electric powered electricity, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, complex qualities and framework type
four.1 This collection of motors undertake a box construction, the body is welded by metal plates into a box kind, mild fat, good rigidity, the prime of the motor is outfitted with a protective leading include or cooler, which is hassle-free for motor warmth dissipation, set up and upkeep.
four.two The stator is made of substantial-high quality low-reduction silicon steel sheets laminated in sections to make certain the top quality of the iron core, so as to reduce iron core reduction and enhance effectiveness. The stator winding is created of F-course insulating material, which has sturdy insulation face up to voltage and anti-corona potential. The winding ends are reliably set and tied, and vacuum pressure impregnation solvent-free paint approach (VPI) is utilized, so the motor’s insulation overall performance Superb and reputable, substantial mechanical energy, robust moisture resistance and long service life.
four.3 Our firm styles a enthusiast dimension in the exact same center, higher and the same pole number in accordance to 1-two electrical power files, every single admirer calculates the air inlet and outlet angles in detail, and utilizes Ansys to assess the partial strain air volume of each and every section of the air duct, and design a sensible air duct The distribution and quantity of air ducts strictly management the wind friction of the motor.
four.four The use of copper row rotors can successfully reduce extra stray losses and decrease rotor bar losses.
four.five Via the German LDW motor large-electricity and large-performance motor technologies transformation perform, the slot-piece optimized construction is adopted, the air path is optimized, and the overall wind resistance of the motor is diminished to decrease the total wind route decline.
4.6 The bearing adopts two types of rolling bearing and sliding bearing. It is identified by the electricity and pace of the motor. Its protection degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-end oil injection and drainage gadget, which is simple for consumers to use and maintain.
4.seven The main junction box is put on the appropriate side of the motor (seen from the extension end of the major shaft), or it can be placed on the left facet according to consumer requirements. Independent grounding terminals are offered inside and outside the house the junction box.
4.eight In accordance to user needs, temperature measuring gadgets can be extra to crucial elements these kinds of as stator windings and bearings to aid on-internet site observation and distant monitoring to make certain safe and trustworthy procedure of the motor.
