CZPT description
Y,YKS,YKK Sequence large voltage three-stage asynchronous motors (Body No.355-1000) mounting dimensions and tolerance are coincident with China regular GB755, CZPT CZPTal committee common IEC34-oneand machinery-career standards JB/T/7593 JB/T1571.1 and many others.
The grade of protection for outer protect is in accordance with GB4942 and IEC34-five common, there are four grades IP23, IPW24, IP44 and IP54. The IP23 quality can update to IP44(Tube Ventilation) according the customer’s ask for. Also offer other protecting grade specially.
The cooling technique is according to the GB/T1993 and IEC34-6 regular . There are three sorts of cooling method IC01,IC611 and IC81W. Also we can supply other cooling technique in accordance the buyer ask for.
The structure and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) specifications.

Framework specification       
The frame is created of steel plate getting welded up into kind of sq. tank form with light-weight excess weight and organization rigidity .
Stator is a outer-press-assembly construction, the stator winding is a F grade insulation, at the winding’s conclude part currently being company banded.
The complete stator has been handled with VPI technological innovation to make stator with a sturdy body and good electrical and dampness resistance.
The rotor can be produced into two modes casting aluminum and copper bar mode. 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 and every finish to be soldered with a finish-ring by trustworthy soldering technology. At the stop of approach, it must be immersed in lacquer as soon as to strengthen the integration.
Possibly rolling or sleeve bearing may possibly be adopted, the safety grade of bearing is IP54. For the rolling bearings manner, the rolling bearing have to be lubricated with grease, and the motor have to have oil-inlet and oil-exhaust products, motor can also be non-cease oil injection. For the sleeve bearing method, the oil offer method for the bearing must be well prepared by customers. But the efficiency for sleeve bearing motor will be permitted a minor decrease with regard of the technological knowledge table and that is permissible in according with the relative stipulates of the regular issued by Ministry of Machine Building.
The major terminal box is made by Germany DIN standard. The quality of protection is IP54. The terminal box for standard motor is located at the correct facet (Considered from axle extension). Also can be mounted at still left aspect in accordance customer’s need. The outlet hole of terminal box can experience up, down, right and remaining four directions. There is a impartial grounded unit in the primary terminal box.
Normally the motors axle is solitary extension mode, the crucial is a planar key manner. We also can provide double shaft extension mode in accordance customer’s requirement.
We can put in temperature measurements in stator and bearings. And put in interior room heaters for humidity protecting in the course of stoppage.

The Implication of the symbol
By GB4831 stipulation, the motor’s sort is composed of item image and specification image in sequence.
The product symbol is demons dealt with by motor collection symbols, its implication is as following:
   Y———squirrel-cage rotor a few-section asynchronous motor.
   YKS——Enclosed squirrel-cage rotor three-phase asynchronous motor with air-water cooler
   YKK—— Enclosed squirrel-cage rotor three-period asynchronous motor with air-air cooler
   The specification image is composed of centre peak, iron-main size number and quantity of poles.

Features 
This motor can be processed by the anticorrosion anti-mould-proof method to derive out of doors (W) and out of doors corrosion protection (WF) motors. Higher performance, energy saving, lower vibration, little size, gentle bodyweight, dependable performance and straightforward installation and routine maintenance. The frame is manufactured of steel plate becoming welded up into kind of square tank shape with light-weight fat and company rigidity. Stator is an outer-push-assembly construction. The stator winding is F grade insulation at the winding’s conclude part currently being agency banded. The entire stator has been handled with VPI technologies to make stator with a sturdy body and very good electrical and humidity evidence. The rotor can be produced into casting aluminum rotor or copper bar rotor. The copper cage rotor guide bar and conclude ring are welded by intermediate frequency, and the copper information bar diameter groove is treated with strong technological innovation to make it have high trustworthiness.

Purposes 
Best for driving all sorts of basic equipment, such as h2o pump, fan, compressor, crusher and and many others.
