I. Overview
YLYLKSYLKK sequence large-voltage cage-sort three-phase asynchronous motors have seven middle heights from H315 to H710. The business adopts advanced technology at residence and overseas, by means of a experienced and dependable design and production program, and combines the style and manufacture of motors by our organization for a lot of a long time. Knowledge, compute and optimize the layout of the different losses of the motor, the wind resistance of each wind route, and the toughness of every single part. The use of high-good quality resources and scientific processing technology in the manufacturing can make the series motors have the benefits of high effectiveness, low noise, reduced vibration, large reliability and hassle-free set up and upkeep.
This sequence of motors can be utilized to generate different standard machinery this sort of as drinking water pumps, compressors and other mechanical tools, and are commonly employed in electrical electricity, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, technical characteristics and construction type
four.one This sequence of motors undertake a box-kind framework. The frame is welded from steel plates into a box-kind, with sturdy ribs and excellent power. The

motor is equipped with a protective cover or cooler to facilitate the motor’s heat dissipation, installation and upkeep.
four.two The stator adopts an external press-match structure, and the stator and rotor are punched from minimal-loss non-oriented cold-rolled silicon metal sheets. The stator winding is produced of F-course insulation materials, which has strong insulation endure voltage and anti-corona ability. The winding finishes are reliably mounted and tied, and vacuum force impregnation solvent-free of charge paint procedure (VPI) is used, so the motor’s insulation functionality Exceptional and dependable, higher mechanical energy, robust dampness resistance and lengthy support daily life.
four.three The rotor cage bar can be created of cast aluminum or copper in accordance to overall performance parameters or user demands. Between them, the cast aluminum cage bar and the end ring are integrally cast by centrifugal to make sure the mechanical energy and prevent the cage bar from breaking throughout the motor operation the copper bar rotor is manufactured of higher-good quality copper material, and the cage bar is welded with the end ring by intermediate frequency welding. The welding high quality is great. Large energy, and by way of the fastening procedure in the groove, greatly lessen the phenomenon of broken copper bars.
4.four When the motor has no axial thrust, the bearing adopts rolling bearing, and its security grade is IP23IP44, IP54 or IP55. The rolling bearing is geared up with non-quit oil injection and drainage system, which is simple for users to use and keep. When bearing axial thrust, thrust sliding bearing can be utilized.
four.five According to consumer specifications, temperature measurement units can be included to crucial areas such as stator windings and bearings to facilitate on-internet site observation and remote monitoring to make certain safe and dependable operation of the motor.
five. Problems of use
five.1 Ambient air temperature: -25ºC~50ºC
five.2 Altitude: no more than 5000 m
five.3 Rated frequency: 50Hz, allowable frequency deviation ±1%
five.4 In the course of voltage operation, the allowable voltage deviation is ±5%. (It can operate at ±10% under the circumstances of 7.3 in GB 755)
