CZPT description
Y,YKS,YKK Series high voltage a few-stage asynchronous motors (Body No.355-a thousand) mounting proportions and tolerance are coincident with China standard GB755, CZPT CZPTal committee standard IEC34-1and equipment-job standards JB/T/7593 JB/T1571.1 and so forth.
The quality of defense for outer include is in accordance with GB4942 and IEC34-five common, 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 supply other protecting grade specially.
The cooling strategy is according to the GB/T1993 and IEC34-six common . There are 3 kinds of cooling approach IC01,IC611 and IC81W. Also we can provide other cooling technique according the buyer ask for.
The framework and mounting design is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) standards.

Construction specification       
The frame is produced of metal plate becoming welded up into type of sq. tank shape with mild weight and organization rigidity .
Stator is a outer-press-assembly structure, the stator winding is a F grade insulation, at the winding’s end element becoming firm banded.
The total stator has been handled with VPI technologies to make stator with a robust physique and good electrical and moisture resistance.
The rotor can be designed into two modes casting aluminum and copper bar mode. 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 finish-ring by dependable soldering technological innovation. At the finish of process, it should be immersed in lacquer as soon as to strengthen the integration.
Possibly rolling or sleeve bearing may be adopted, the security grade of bearing is IP54. For the rolling bearings manner, the rolling bearing need to be lubricated with grease, and the motor need to have oil-inlet and oil-exhaust units, motor can also be non-cease oil injection. For the sleeve bearing method, the oil offer system for the bearing must be ready by customers. But the effectiveness for sleeve bearing motor will be permitted a tiny lower with regard of the technological data desk and that is permissible in in accordance with the relative stipulates of the normal issued by Ministry of Device Developing.
The major terminal box is designed by Germany DIN regular. The grade of protection is IP54. The terminal box for common motor is positioned at the appropriate aspect (Seen from axle extension). Also can be mounted at left facet according customer’s requirement. The outlet hole of terminal box can face up, down, proper and still left 4 directions. There is a independent grounded gadget in the main terminal box.
Typically the motors axle is one extension method, the essential is a planar key method. We also can offer double shaft extension manner according customer’s prerequisite.
We can put in temperature measurements in stator and bearings. And install inner place heaters for dampness guarding in the course of stoppage.

The Implication of the symbol
By GB4831 stipulation, the motor’s kind is composed of merchandise image and specification image in sequence.
The item image is demons taken care of by motor collection symbols, its implication is as subsequent:
   Y———squirrel-cage rotor 3-section asynchronous motor.
   YKS——Enclosed squirrel-cage rotor a few-section asynchronous motor with air-h2o cooler
   YKK—— Enclosed squirrel-cage rotor three-section asynchronous motor with air-air cooler
   The specification image is composed of centre height, iron-core size quantity and number of poles.
Example:

Specifics
YKK sequence:

• Body sizes: 355-1000                   
• Rated output: 185-8000kW
• Insulation class: F                         
• Diploma of defense: IP54 /IP55
• Enclosure: IC611                           
• Mounting: Horizontal
• Rotor: Squirrel cage                     
• CZPT: Rolling bearing or sleeve bearing
• Voltage: 6kV, 10kV

Features 
This motor can be processed by the anticorrosion anti-mould-evidence approach to derive out of doors (W) and out of doors corrosion protection (WF) motors. Large effectiveness, energy preserving, lower vibration, little dimension, gentle bodyweight, reliable efficiency and simple installation and routine maintenance. The body is made of steel plate being welded up into sort of sq. tank form with mild fat and firm rigidity. Stator is an outer-push-assembly construction. The stator winding is F grade insulation at the winding’s conclude part being company banded. The complete stator has been treated with VPI technologies to make stator with a strong physique and excellent electric powered and humidity evidence. The rotor can be developed into casting aluminum rotor or copper bar rotor. The copper cage rotor manual bar and stop ring are welded by intermediate frequency, and the copper guide bar diameter groove is taken care of with strong technology to make it have higher dependability.

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