Core Technical Strengths – The Foundation of Superior Quality
Innovative Wound Rotor Design
The YRKK series uses advanced wound rotor technology with external resistors or liquid resistance starters, enabling smooth starting and effective speed control. Compared with conventional squirrel cage motors, this design significantly reduces grid impact and is ideal for applications with limited power supply capacity.
Efficient Air-to-Air Cooling System
Equipped with an IC611 cooling system, the motor uses a high-efficiency air-to-air heat exchanger to maintain optimal operating temperatures under continuous heavy-load conditions. This design enhances reliability, extends insulation life, and ensures stable performance in harsh industrial environments.
Optimized Mechanical Structure
The frame and end covers are manufactured from high-strength materials and feature precision structural design. After strict dynamic balancing tests, the motor runs smoothly with minimal vibration, allowing it to withstand heavy load shocks and demanding operating conditions for long-term stable operation.
Reliable Insulation System
The stator windings adopt Class F insulation, treated with anti-corona measures and processed using VPI (Vacuum Pressure Impregnation) technology. This provides excellent resistance to moisture, corrosion, and high temperatures, ensuring reliable insulation performance even in harsh environments.
