IEC Large Voltage Induction Asynchronous Squirrel Cage AC Modular Motor with Air Drinking water Exchanger (YKS) for Cement Metal Shipbuilding Fiber Market
———————————————————————————————
Common description
Y,YKS,YKK Series large voltage three-stage asynchronous motors (Body No.355-1000) mounting proportions and tolerance are coincident with China regular GB755, International Electrical committee standard IEC34-1and machinery-job standards JB/T/7593 JB/T1571.1 and so on.
The grade of defense for outer include is in accordance with GB4942 and IEC34-5 standard, there are 4 grades IP23, IPW24, IP44 and IP54. The IP23 quality can update to IP44(Tube Air flow) according the customer’s request. Also supply other protective quality specially.
The cooling method is according to the GB/T1993 and IEC34-6 regular . There are a few types of cooling method IC01,IC611 and IC81W. Also we can offer other cooling strategy according the customer ask for.
The framework and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) standards.
Framework specification
The frame is manufactured of metal plate being welded up into kind of square tank condition with light-weight excess weight and organization rigidity .
Stator is a outer-push-assembly composition, the stator winding is a F quality insulation, at the winding’s finish part being organization banded.
The complete stator has been treated with VPI technological innovation to make stator with a robust physique and great electrical and dampness resistance.
The rotor can be developed into two modes casting aluminum and copper bar mode. Casting aluminum rotor is casted with pure aluminum. Copper-bar rotor is produced by copper bars wedges in the slots, then at the bar’s each finish to be soldered with a stop-ring by reputable soldering technologies. At the end of method, it must be immersed in lacquer as soon as to improve the integration.
Both rolling or sleeve bearing may be adopted, the protection grade of bearing is IP54. For the rolling bearings manner, the rolling bearing must be lubricated with grease, and the motor need to have oil-inlet and oil-exhaust units, motor can also be non-quit oil injection. For the sleeve bearing mode, the oil supply system for the bearing must be geared up by customers. But the efficiency for sleeve bearing motor will be permitted a tiny decrease with respect of the specialized info table and that is permissible in according with the relative stipulates of the regular issued by Ministry of Equipment Creating.
The primary terminal box is created by Germany DIN normal. The quality of defense is IP54. The terminal box for standard motor is found at the correct facet (Seen from axle extension). Also can be mounted at left facet according customer’s need. The outlet gap of terminal box can confront up, down, right and remaining four directions. There is a impartial grounded unit in the main terminal box.
Generally the motors axle is one extension mode, the crucial is a planar key method. We also can give double shaft extension mode in accordance customer’s necessity.
We can install temperature measurements in stator and bearings. And put in interior space heaters for humidity safeguarding throughout stoppage.
The Implication of the symbol
By GB4831 stipulation, the motor’s variety is composed of solution symbol and specification symbol in sequence.
The solution symbol is demons dealt with by motor sequence symbols, its implication is as subsequent:
Y———squirrel-cage rotor 3-period asynchronous motor.
YKS——Enclosed squirrel-cage rotor three-phase asynchronous motor with air-drinking water cooler
YKK—— Enclosed squirrel-cage rotor 3-phase asynchronous motor with air-air cooler
The specification symbol is composed of centre peak, iron-core duration variety and variety of poles.

Functions
Substantial efficiency, energy conserving, reduced vibration, modest dimensions, mild excess weight, dependable overall performance and effortless set up and servicing. The body is created of steel plate becoming welded up into type of square tank condition with gentle fat and agency rigidity. Stator is an outer-press-assembly structure. The stator winding is F quality insulation at the winding’s stop part being agency banded. The total stator has been treated with VPI technologies to make stator with a strong physique and excellent electric and moisture evidence. The rotor can be developed into casting aluminum rotor or copper bar rotor. The copper cage rotor manual bar and conclude ring are welded by intermediate frequency, and the copper information bar diameter groove is treated with strong technology to make it have high trustworthiness.
Apps
Best for driving all varieties of standard machinery, such as h2o pump, admirer, compressor, ball mill and etc.
