CZPT description
Y,YKS,YKK Sequence large voltage 3-stage asynchronous motors (Frame No.355-1000) mounting proportions and tolerance are coincident with China standard GB755, CZPT CZPTal committee normal IEC34-1and machinery-occupation specifications JB/T/7593 JB/T1571.1 and so on.
The quality of security for outer go over 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 Ventilation) in accordance the customer’s request. Also supply other protective quality specially.
The cooling approach is according to the GB/T1993 and IEC34-six standard . There are three types of cooling strategy IC01,IC611 and IC81W. Also we can provide other cooling method in accordance the client request.
The structure and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) expectations.

Structure specification       
The frame is produced of steel plate getting welded up into type of sq. tank condition with light-weight weight and agency rigidity .
Stator is a outer-push-assembly framework, the stator winding is a F quality insulation, at the winding’s conclude element being organization banded.
The entire stator has been treated with VPI technologies to make stator with a sturdy human body and good electrical and humidity resistance.
The rotor can be designed into two modes casting aluminum and copper bar manner. Casting aluminum rotor is casted with pure aluminum. Copper-bar rotor is manufactured by copper bars wedges in the slots, then at the bar’s each stop to be soldered with a stop-ring by reputable soldering technological innovation. At the end of approach, it should be immersed in lacquer once to reinforce the integration.
Both rolling or sleeve bearing may be adopted, the security quality of bearing is IP54. For the rolling bearings mode, the rolling bearing have to be lubricated with grease, and the motor should have oil-inlet and oil-exhaust devices, motor can also be non-end oil injection. For the sleeve bearing manner, the oil supply method for the bearing need to be ready by consumers. But the performance for sleeve bearing motor will be permitted a minor lower with regard of the specialized knowledge table and that is permissible in in accordance with the relative stipulates of the regular issued by Ministry of Device Building.
The primary terminal box is created by Germany DIN common. The quality of protection is IP54. The terminal box for normal motor is located at the appropriate side (Viewed from axle extension). Also can be mounted at left facet in accordance customer’s need. The outlet gap of terminal box can face up, down, right and remaining four directions. There is a impartial grounded system in the major terminal box.
Generally the motors axle is one extension manner, the crucial is a planar crucial manner. We also can supply double shaft extension manner in accordance customer’s requirement.
We can put in temperature measurements in stator and bearings. And install interior place heaters for dampness guarding in the course of stoppage.

The Implication of the image
By GB4831 stipulation, the motor’s variety is composed of solution symbol and specification image in sequence.
The solution image is demons treated by motor sequence symbols, its implication is as subsequent:
   Y———squirrel-cage rotor 3-phase asynchronous motor.
   YKS——Enclosed squirrel-cage rotor a few-stage asynchronous motor with air-drinking water cooler
   YKK—— Enclosed squirrel-cage rotor three-section asynchronous motor with air-air cooler
   The specification symbol is composed of centre peak, iron-core size amount and number of poles.
Example:

Specifics
YKK collection:

• Body sizes: 355-1000                   
• Rated output: 185-8000kW
• Insulation class: F                         
• Diploma of protection: IP54 /IP55
• Enclosure: IC611                           
• Mounting: Horizontal
• Rotor: Squirrel cage                     
• CZPT: Rolling bearing or sleeve bearing

Features 
This motor can be processed by the anticorrosion anti-mould-proof method to derive outside (W) and outside corrosion security (WF) motors. High performance, vitality saving, minimal vibration, tiny measurement, light-weight excess weight, trustworthy functionality and straightforward installation and servicing. The frame is made of steel plate getting welded up into kind of square tank shape with gentle weight and organization rigidity. Stator is an outer-push-assembly framework. The stator winding is F grade insulation at the winding’s end portion getting firm banded. The complete stator has been dealt with with VPI technological innovation to make stator with a robust human body and good electric powered and humidity evidence. The rotor can be designed into casting aluminum rotor or copper bar rotor. The copper cage rotor guidebook bar and conclude ring are welded by intermediate frequency, and the copper guidebook bar diameter groove is treated with sound technological innovation to make it have higher trustworthiness.

Applications 
Excellent for driving all varieties of common machinery, this sort of as drinking water pump, admirer, compressor, crusher and and many others.
