Slipring Induction Motor of Variety B3 250Kw voltage 6000V 50 Hz r.p.m. 1489 technique cooling IC611 Temperature Increase B CZPTs SLEEVE
Y,YKS,YKK Sequence high voltage 3-stage asynchronous motors (Body No.355-a thousand) mounting dimensions and tolerance are coincident with China regular GB755, CZPT CZPTal committee normal IEC34-1and equipment-profession specifications JB/T/7593 JB/T1571.1 etc.
The quality of safety for outer go over is in accordance with GB4942 and IEC34-five normal, there are 4 grades IP23, IPW24, IP44 and IP54. The IP23 quality can update to IP44(Tube Ventilation) according the customer’s request. Also provide other protecting grade specifically.
The cooling method is according to the GB/T1993 and IEC34-6 regular . There are 3 varieties of cooling strategy IC01,IC611 and IC81W. Also we can supply other cooling strategy in accordance the consumer ask for.
The structure and mounting product is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) requirements.
The frame is made of steel plate being welded up into kind of sq. tank form with light weight and organization rigidity .
Stator is a outer-push-assembly framework, the stator winding is a F quality insulation, at the winding’s stop portion becoming agency banded.
The whole stator has been handled with VPI technologies to make stator with a strong body and very good electrical and dampness resistance.
The rotor can be designed into two modes casting aluminum and copper bar method. 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 reliable soldering technology. At the conclude of method, it should be immersed in lacquer after to improve the integration.
Either rolling or sleeve bearing may possibly be adopted, the defense grade of bearing is IP54. For the rolling bearings method, the rolling bearing have to be lubricated with grease, and the motor need to have oil-inlet and oil-exhaust products, motor can also be non-quit oil injection. For the sleeve bearing mode, the oil provide technique for the bearing need to be geared up by customers. But the effectiveness for sleeve bearing motor will be permitted a tiny lessen with regard of the complex data desk and that is permissible in according with the relative stipulates of the common issued by Ministry of Device Building.
The major terminal box is made by Germany DIN common. The grade of security is IP54. The terminal box for normal motor is situated at the correct side (Considered from axle extension). Also can be mounted at remaining facet according customer’s need. The outlet gap of terminal box can encounter up, down, appropriate and left four directions. There is a independent grounded unit in the principal terminal box.
Generally the motors axle is single extension manner, the important is a planar crucial mode. We also can supply double shaft extension method according customer’s need.
We can put in temperature measurements in stator and bearings. And install interior room heaters for humidity protecting in the course of stoppage.
The Implication of the image
By GB4831 stipulation, the motor’s kind is composed of solution image and specification symbol in sequence.
The item image is demons treated by motor collection symbols, its implication is as adhering to:
Y———squirrel-cage rotor 3-stage asynchronous motor.
YKS——Enclosed squirrel-cage rotor three-phase asynchronous motor with air-drinking water cooler
YKK—— Enclosed squirrel-cage rotor 3-section asynchronous motor with air-air cooler
The specification image is composed of centre height, iron-main duration quantity and variety of poles.

This motor can be processed by the anticorrosion anti-mould-proof method to derive outside (W) and outdoor corrosion protection (WF) motors. Large performance, energy conserving, reduced vibration, small size, light weight, trustworthy efficiency and straightforward set up and maintenance. The body is produced of steel plate currently being welded up into form of sq. tank shape with gentle bodyweight and agency rigidity. Stator is an outer-push-assembly construction. The stator winding is F quality insulation at the winding’s end element currently being organization banded. The total stator has been dealt with with VPI technology to make stator with a sturdy physique and good electrical and humidity evidence. The rotor can be developed into casting aluminum rotor or copper bar rotor. The copper cage rotor information bar and end ring are welded by intermediate frequency, and the copper information bar diameter groove is treated with strong engineering to make it have substantial reliability.
Ideal for driving all varieties of common equipment, such as water pump, supporter, compressor, crusher and and many others.
