Product Description

Squirrel Cage Rotor Medium Voltage AC Induction Motor High Voltage Motor Asynchronous Motors
---------------------------------------------------------------------------------------------

General description
Y,YKS,YKK Series high voltage three-phase asynchronous motors (Frame No.355-1000) mounting dimensions and tolerance are coincident with China standard GB755<Rotating Electrical Machines-Rating and Performance>, International Electrical committee standard IEC34-1<Rotating Electrical Machines-Rating and Performance>and machinery-profession standards JB/T/7593 JB/T10315.1 etc.
The grade of protection for outer cover is in accordance with GB4942 and IEC34-5 <Rotating electrical machines- enclosure ingress protection>standard, there are four grades IP23, IPW24, IP44 and IP54. The IP23 grade can update to IP44(Tube Ventilation) according the customer's request. Also provide other protective grade specially.
The cooling method is according to the GB/T1993 and IEC34-6 standard <Cooling method of Rotating Electrical Machines>. There are three kinds of cooling method IC01,IC611 and IC81W. Also we can provide other cooling method according the customer request.
The structure and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 <Classification of types of construction and mounting arrangements for rotating electrical machines>(IM code) standards.

Structure specification       
The frame is made of steel plate being welded up into form of square tank shape with light weight and firm rigidity .
Stator is a outer-press-assembly structure, the stator winding is a F grade insulation, at the winding's end part being firm banded.
The whole stator has been treated with VPI technology to make stator with a robust body and good electrical and moisture resistance.
The rotor can be developed into two modes casting aluminum and copper bar mode. 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 end to be soldered with a end-ring by reliable soldering technology. At the end of process, it must be immersed in lacquer once to strengthen the integration.
Either rolling or sleeve bearing may be adopted, the protection grade of bearing is IP54. For the rolling bearings mode, the rolling bearing must be lubricated with grease, and the motor must have oil-inlet and oil-exhaust devices, motor can also be non-stop oil injection. For the sleeve bearing mode, the oil supply system for the bearing must be prepared by customers. But the efficiency for sleeve bearing motor will be permitted a little decrease with respect of the technical data table and that is permissible in according with the relative stipulates of the standard issued by Ministry of Machine Building.
The main terminal box is designed by Germany DIN standard. The grade of protection is IP54. The terminal box for standard motor is located at the right side (Viewed from axle extension). Also can be mounted at left side according customer's requirement. The outlet hole of terminal box can face up, down, right and left four directions. There is a independent grounded device in the main terminal box.
Normally the motors axle is single extension mode, the key is a planar key mode. We also can provide double shaft extension mode according customer's requirement.
We can install temperature measurements in stator and bearings. And install inner space heaters for moisture protecting during stoppage.

The Implication of the symbol
By GB4831 stipulation, the motor's type is composed of product symbol and specification symbol in sequence.
The product symbol is demons treated by motor series symbols, its implication is as following:
   Y---------squirrel-cage rotor three-phase asynchronous motor.
   YKS------Enclosed squirrel-cage rotor three-phase asynchronous motor with air-water cooler
   YKK------ Enclosed squirrel-cage rotor three-phase asynchronous motor with air-air cooler
   The specification symbol is composed of centre height, iron-core length number and number of poles.

Features 
This motor can be processed by the anticorrosion anti-mould-proof process to derive outdoor (W) and outdoor corrosion protection (WF) motors. High efficiency, energy saving, low vibration, small size, light weight, reliable performance and easy installation and maintenance. The frame is made of steel plate being welded up into form of square tank shape with light weight and firm rigidity. Stator is an outer-press-assembly structure. The stator winding is F grade insulation at the winding's end part being firm banded. The whole stator has been treated with VPI technology to make stator with a robust body and good electric and moisture proof. The rotor can be developed into casting aluminum rotor or copper bar rotor. The copper cage rotor guide bar and end ring are welded by intermediate frequency, and the copper guide bar diameter groove is treated with solid technology to make it have high reliability.

Applications 
Ideal for driving all kinds of general machinery, such as water pump, fan, compressor, crusher and etc.
