Y, YKS, YKK series substantial-voltage cage 3-phase asynchronous motors

one. Overview
Y, YKS, YKK collection medium and large large voltage cage 3-section asynchronous motors have twelve center heights from H355 to H1250. The firm adopts advanced engineering at home and abroad, by means of a experienced and dependable design and style and production method, and brings together the firm’s several several years of medium and large large voltage The new sequence of items created by the experience of AC motor production have the positive aspects of higher effectiveness, minimal sound, low vibration, higher reliability and hassle-free installation and routine maintenance.
The electricity grade and set up dimensions of this series of motors comply with my country’s standards and the CZPT Electrotechnical Commission’s IEC specifications, and can be employed as a total set of export tools and a substitute for imported items.
This series of motors can be utilised to travel numerous general equipment these kinds of as fans, pumps, compressors and other mechanical products, and are broadly employed in electric powered power, equipment, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, technological characteristics and framework variety
 4.1 This series of motors adopts a box composition, the body is welded from metal plates into a box condition, light weight, and excellent rigidity. A protective leading include or cooler is installed on the prime of the motor to aid the heat dissipation, installation and upkeep of the motor.
four.two The stator adopts an external push-match construction, and the stator and rotor are punched from minimal-reduction non-oriented chilly-rolled silicon steel sheets. The stator winding is produced of F-course insulation materials, which has sturdy insulation endure voltage and anti-corona potential. The winding finishes are reliably fixed and tied, and are dealt with with vacuum pressure impregnation solvent-free paint (VPI) procedure, so the motor insulation functionality Outstanding and reputable, substantial mechanical toughness, sturdy moisture resistance and prolonged service life.
4.3 The rotor cage bar can be manufactured of forged aluminum or copper according to functionality parameters or user needs. Among them, the solid aluminum cage bar and the conclude ring are integrally forged by centrifugal to ensure the mechanical toughness and avoid the cage bar from breaking for the duration of the motor procedure the copper bar rotor is created of substantial-quality copper materials, and the cage bar is welded with the stop ring by intermediate frequency welding. The welding high quality is good. Higher energy, and via the fastening process in the groove, drastically lessen the phenomenon of broken copper bars.
four.four The bearing adopts two varieties of rolling bearing and sliding bearing. It is determined by the electricity and pace of the motor. Its safety stage is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-quit oil injection and drainage device, which is effortless for consumers to use and maintain.
four.5 The primary junction box is placed on the appropriate aspect of the motor (seen from the extension conclude of the primary shaft), or it can be put on the left side in accordance to user demands. Separate ground terminals are provided within and outdoors the junction box.
4.six According to consumer requirements, temperature measurement units can be extra to critical parts this kind of as stator windings and bearings to facilitate on-internet site observation and distant monitoring to make certain secure and reputable procedure of the motor.
5. Problems of use
5.one Ambient air temperature: -fifteen ºC~40ºC
five.2 Altitude: not more than 1000m
5.3 Rated frequency: 50HZ, allowable frequency deviation ±2%
5.four Throughout rated procedure, the allowable voltage deviation is ±5%. (It can run at ±10% under the problems of 7.three in GB 755)
