YX2 Series 6 kV High-Efficiency, High-Voltage, Compact Three-Phase Induction Motors – Product Introduction

The YX2 series 6 kV high-efficiency, high-voltage, compact three-phase induction motors feature a high-strength cast iron frame. The stator employs Class F insulation processed via vacuum pressure impregnation (VPI) with solvent-free resin. The rotor is squirrel-cage type; alternatively, upon customer request, it can be manufactured using one-step die-cast aluminum or copper-bar rotor construction. This series offers compact structure, small footprint, high reliability, attractive appearance, low noise, low vibration, and convenient operation and maintenance. They are suitable for fans, pumps, compressors, construction machinery, mining equipment, and other applications.

YX2 Series 6 kV High-Efficiency, High-Voltage, Compact Three-Phase Induction Motors – Key Advantages:

1. Optimized Electromagnetic Design

This motor series features an optimized electromagnetic design. Dimensions, air gap, slot matching, and slot geometry have all been comprehensively optimized to rationally adjust motor dimensions and enhance overall motor performance.

2. Low-Harmonic Winding

The series adopts low-harmonic windings to reduce stator copper losses and parasitic losses, thereby improving motor operating efficiency.

3. High-Strength Magnetic Slot Wedges

Through extensive R&D, our company has successfully resolved the issue of magnetic slot wedge dislodgement by adopting high-strength magnetic slot wedges, stable wedge clamping techniques, and advanced materials—significantly enhancing motor electrical performance.

4. Optimized Cooling and Ventilation System

A backward-curved centrifugal fan is employed, and the fan shaft orientation is optimized to improve both internal and external motor ventilation. This enhances cooling effectiveness, reduces ventilation losses (especially in high-speed motors), lowers ventilation noise, and improves motor efficiency.

5. Insulation System

This series incorporates advanced insulation systems whose performance has been thoroughly enhanced. Test results—including dielectric loss tangent (tgδ) vs. voltage, tgδ vs. temperature, flexural strength, breakdown voltage, thermal aging, and electrical aging—demonstrate that this insulation system meets world-class standards. Premium mica tape and eco-friendly resin impregnants are used; each coil is wound, expanded, and taped on CNC winding machines, expansion machines, and taping machines, followed by final VPI processing. Consequently, the insulation exhibits excellent reliability, superior mechanical strength, and strong moisture resistance.

6. High Efficiency

Motor efficiency complies with JB/T7593, JB/T10315.1, JB/T10315.2, and GB/T13957 standards, achieving IE2 high-efficiency motor requirements based on a 20% reduction in losses. These are truly high-efficiency motors that significantly boost customer operational efficiency and contribute to national energy conservation.
