IEC Large Voltage Induction Asynchronous Squirrel Cage AC Modular Motor with Air-air Warmth Exchanger (YKK) for Cement Sugar Oil Gas Marine Metallic
———————————————————————————————
Common description
Y,YKS,YKK Sequence higher voltage three-phase asynchronous motors (Frame No.355-one thousand) mounting proportions and tolerance are coincident with China standard GB755, Worldwide Electrical committee regular IEC34-oneand equipment-job specifications JB/T/7593 JB/T1571.1 etc.
The grade of protection for outer cover is in accordance with GB4942 and IEC34-5 regular, there are 4 grades IP23, IPW24, IP44 and IP54. The IP23 quality can update to IP44(Tube Air flow) in accordance the customer’s request. Also provide other protective quality specially.
The cooling approach is in accordance to the GB/T1993 and IEC34-6 regular . There are 3 kinds of cooling strategy IC01,IC611 and IC81W. Also we can offer other cooling technique in accordance the customer ask for.
The structure and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) specifications.
Structure specification
The body is manufactured of metal plate getting welded up into sort of sq. tank form with gentle weight and firm rigidity .
Stator is a outer-push-assembly construction, the stator winding is a F quality insulation, at the winding’s finish part currently being company banded.
The whole stator has been handled with VPI technological innovation to make stator with a strong physique and great electrical and dampness 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 made by copper bars wedges in the slots, then at the bar’s each finish to be soldered with a stop-ring by trustworthy soldering technologies. At the conclude of procedure, it need to be immersed in lacquer when to reinforce the integration.
Either rolling or sleeve bearing could be adopted, the security quality 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 devices, motor can also be non-stop oil injection. For the sleeve bearing method, the oil supply program for the bearing need to be ready by clients. But the effectiveness for sleeve bearing motor will be permitted a little lessen with respect of the specialized info table and that is permissible in according with the relative stipulates of the common issued by Ministry of Equipment Constructing.
The main terminal box is designed by Germany DIN normal. The quality of protection is IP54. The terminal box for regular motor is located at the right side (Considered from axle extension). Also can be mounted at left facet in accordance customer’s requirement. The outlet hole of terminal box can encounter up, down, right and still left four instructions. There is a independent grounded device in the major terminal box.
Generally the motors axle is single extension mode, the essential is a planar crucial manner. We also can supply double shaft extension manner according customer’s prerequisite.
We can install temperature measurements in stator and bearings. And put in inner place heaters for humidity guarding for the duration of stoppage.
The Implication of the symbol
By GB4831 stipulation, the motor’s type is composed of solution image and specification symbol in sequence.
The item symbol is demons treated by motor collection symbols, its implication is as pursuing:
Y———squirrel-cage rotor three-stage asynchronous motor.
YKS——Enclosed squirrel-cage rotor three-phase asynchronous motor with air-h2o cooler
YKK—— Enclosed squirrel-cage rotor three-period asynchronous motor with air-air cooler
The specification image is composed of centre peak, iron-main length variety and variety of poles.
Example:
Details
YKK collection:
- Body sizes: 355-1000
- Rated output: 185-8000kW
- Insulation course: F
- Diploma of security: IP54 /IP55
- Enclosure: IC611
- Mounting: Horizontal
- Rotor: Squirrel cage
- Bearing: Rolling bearing or sleeve bearing
- Voltage: 6kV, 10kV
Features
This motor can be processed by the anticorrosion anti-mould-proof method to derive outdoor (W) and outside corrosion security (WF) motors. High effectiveness, vitality conserving, low vibration, tiny dimensions, gentle weight, trustworthy overall performance and effortless installation and routine maintenance. The frame is made of metal plate being welded up into sort of sq. tank shape with light excess weight and company rigidity. Stator is an outer-push-assembly construction. The stator winding is F grade insulation at the winding’s conclude part getting company banded. The total stator has been treated with VPI technology to make stator with a strong body and excellent electric and dampness evidence. The rotor can be designed into casting aluminum rotor or copper bar rotor. The copper cage rotor guidebook bar and finish ring are welded by intermediate frequency, and the copper guide bar diameter groove is handled with solid technology to make it have higher trustworthiness.
Programs
Excellent for driving all types of general machinery, this sort of as h2o pump, fan, compressor, crusher and and many others.
