YLKK Series Documentation

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.

Ideal for driving all kinds of water pump. The protection grade is higher than YL series motor.
