Slipring Induction Motor of Kind B3 250Kw voltage 6000V fifty Hz r.p.m. 1489 method cooling IC611 Degree of security IP55 or better mounting IM1001
---------------------------------------------------------------------------------------------
CZPT description
Y,YKS,YKK Series higher voltage a few-period asynchronous motors (Body No.355-one thousand) mounting proportions and tolerance are coincident with China normal GB755, CZPT CZPTal committee regular IEC34-oneand equipment-job standards JB/T/7593 JB/T1571.1 and so forth.
The quality of security for outer cover is in accordance with GB4942 and IEC34-5 standard, there are four grades IP23, IPW24, IP44 and IP54. The IP23 grade can update to IP44(Tube Ventilation) according the customer's ask for. Also offer other protecting quality specifically.
The cooling approach is according to the GB/T1993 and IEC34-six normal . There are a few kinds of cooling strategy IC01,IC611 and IC81W. Also we can supply other cooling strategy according the buyer request.
The structure and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) expectations.
Construction specification
The body is made of steel plate becoming welded up into type of sq. tank condition with light bodyweight and company rigidity .
Stator is a outer-press-assembly structure, the stator winding is a F quality insulation, at the winding's conclude component getting company banded.
The total stator has been treated with VPI technology to make stator with a sturdy human body and very good electrical and moisture resistance.
The rotor can be produced 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 and every stop to be soldered with a conclude-ring by trustworthy soldering technologies. At the finish of approach, it have to be immersed in lacquer after to bolster the integration.
Either rolling or sleeve bearing may possibly 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 should have oil-inlet and oil-exhaust products, motor can also be non-end oil injection. For the sleeve bearing mode, the oil offer method for the bearing must be geared up by buyers. But the efficiency for sleeve bearing motor will be permitted a small lessen with regard of the technical information desk and that is permissible in according with the relative stipulates of the standard issued by Ministry of Equipment Creating.
The principal terminal box is made by Germany DIN regular. The quality of security is IP54. The terminal box for standard motor is situated at the appropriate side (Considered from axle extension). Also can be mounted at still left side according customer's requirement. The outlet hole of terminal box can encounter up, down, appropriate and remaining four directions. There is a impartial grounded gadget in the major terminal box.
Generally the motors axle is single extension mode, the key is a planar crucial mode. We also can provide double shaft extension mode in accordance customer's requirement.
We can install temperature measurements in stator and bearings. And install inner place heaters for dampness protecting in the course of stoppage.
The Implication of the symbol
By GB4831 stipulation, the motor's type is composed of solution symbol and specification image in sequence.
The product symbol is demons treated by motor sequence symbols, its implication is as pursuing:
Y---------squirrel-cage rotor a few-period asynchronous motor.
YKS------Enclosed squirrel-cage rotor a few-section asynchronous motor with air-water cooler
YKK------ Enclosed squirrel-cage rotor a few-period asynchronous motor with air-air cooler
The specification image is composed of centre peak, iron-core length number and number of poles.
Example:

Features
This motor can be processed by the anticorrosion anti-mould-evidence procedure to derive out of doors (W) and out of doors corrosion protection (WF) motors. Higher performance, power preserving, minimal vibration, small size, mild fat, dependable functionality and simple installation and upkeep. The frame is manufactured of metal plate getting welded up into sort of sq. tank shape with mild excess weight and company rigidity. Stator is an outer-push-assembly composition. The stator winding is F quality insulation at the winding's conclude component being firm banded. The total stator has been handled with VPI technological innovation to make stator with a strong physique and great electric powered and dampness proof. The rotor can be produced 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 manual bar diameter groove is taken care of with solid technology to make it have substantial reliability.
Applications
Best for driving all sorts of common machinery, this sort of as water pump, enthusiast, compressor, crusher and and so forth.
