Short description

The latest products developed and produced by Wolong, the YRKS series high-voltage wound rotor three-phase asynchronous motors, represent the pinnacle of Wolong Nanyang’s capabilities.

Description

The YRKS series is a versatile offshoot of the YR series. By customizing the protective cover, these motors can be configured for various cooling methods and protection levels, such as air/water (YRKS) or air/air (YRKK) cooling.

The motors feature a robust, box-type design with a welded steel base, offering both strength and lightweight construction. The removable protective cover allows for easy inspection and maintenance.

The stator is externally mounted and uses F-class insulation for durability. The winding ends are securely fixed, and the entire stator undergoes VPI treatment for moisture and impact resistance.

The rotor can be either cast aluminum or copper bar, both manufactured using advanced techniques. Wound rotors are also VPI-treated and dynamically balanced for smooth operation.
