Y, YKS, YKK collection substantial-voltage cage three-stage asynchronous motors

1. Overview
Y, YKS, YKK collection medium and large large voltage cage a few-section asynchronous motors have twelve middle heights from H355 to H1250. The company adopts advanced engineering at residence and abroad, through a experienced and trustworthy design and style and production program, and combines the company’s numerous many years of medium and big higher voltage The new series of items produced by the expertise of AC motor manufacturing have the benefits of high efficiency, lower sound, reduced vibration, high trustworthiness and handy set up and upkeep.
The electricity grade and installation proportions of this series of motors comply with my country’s standards and the CZPT Electrotechnical Commission’s IEC standards, and can be employed as a complete set of export tools and a substitute for imported items.
This sequence of motors can be utilized to travel a variety of standard equipment these kinds of as fans, pumps, compressors and other mechanical gear, and are commonly employed in electric powered energy, machinery, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, complex characteristics and construction sort
 4.1 This collection of motors adopts a box construction, the frame is welded from metal plates into a box form, light-weight excess weight, and good rigidity. A protective best go over or cooler is installed on the leading of the motor to aid the heat dissipation, installation and maintenance of the motor.
4.2 The stator adopts an external press-fit construction, and the stator and rotor are punched from reduced-decline non-oriented chilly-rolled silicon steel sheets. The stator winding is created of F-course insulation content, which has robust insulation endure voltage and anti-corona capability. The winding finishes are reliably set and tied, and are handled with vacuum pressure impregnation solvent-cost-free paint (VPI) procedure, so the motor insulation efficiency Superb and trustworthy, higher mechanical energy, powerful dampness resistance and extended provider existence.
four.three The rotor cage bar can be produced of solid aluminum or copper according to performance parameters or person specifications. Among them, the cast aluminum cage bar and the end ring are integrally forged by centrifugal to make sure the mechanical energy and avert the cage bar from breaking throughout the motor operation the copper bar rotor is produced of substantial-high quality copper material, and the cage bar is welded with the stop ring by intermediate frequency welding. The welding top quality is excellent. Substantial toughness, and via the fastening process in the groove, tremendously reduce the phenomenon of broken copper bars.
4.4 The bearing adopts two varieties of rolling bearing and sliding bearing. It is decided by the electricity and speed of the motor. Its protection degree is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-quit oil injection and drainage unit, which is simple for users to use and sustain.
four.5 The main junction box is positioned on the proper side of the motor (considered from the extension conclude of the major shaft), or it can be placed on the remaining aspect in accordance to consumer requirements. Individual ground terminals are offered within and outside the house the junction box.
4.six According to user needs, temperature measurement units can be additional to important elements such as stator windings and bearings to aid on-site observation and remote checking to make sure protected and dependable operation of the motor.
5. Circumstances of use
5.1 Ambient air temperature: -15 ºC~40ºC
5.2 Altitude: not much more than 1000m
5.3 Rated frequency: 50HZ, allowable frequency deviation ±2%
five.four In the course of rated procedure, the allowable voltage deviation is ±5%. (It can run at ±10% under the circumstances of seven.three in GB 755)
