YL IEC AC Modular Induction Asynchronous Squirrel Cage Vertical Water Pumps High Voltage Motor
---------------------------------------------------------------------------------------------
General description
YL,YLKK Series medium size high Voltage, three-phase asynchronous motors (Frame No.450-630) mounting dimensions and tolerance are coincident with Chinese 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 Chinese standard GB4942 and IEC34-5 standard<Rotating electrical machines- enclosure ingress protection>. There are four grades IP23 ,IP44 ,IP54 and IP55.
Structure specification
The construction of these series are a international popular tank box shape. The motors frame and end cover are made of steel plate and welded into a form to make it stiff and light weight.
Stator is an outer-press-assembly structure. The stator is made of F grade insulation and corona proof material, a special banding technique is used for winding end part fastening. 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 two modes casting aluminum and copper bar rotor. Casting aluminum rotor is casted with pure aluminum which is reliable in operation and will don't have the phenomenon of rotor conductor to be broken up. The motor's rotor copper conductors and end rings adopt intermediate-frequency welding when the rotor is copper-cage rotor. The rotor copper conductors are featured by high reliability via dealing with tightening craft in trough.

Features
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 is made of F grade insulation and corona proof material, a special banding technique is used for winding end part fastening. 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. It can withstand a lot of axial force.
Applications
Ideal for driving all kinds of water pump.
