YE3 4503-4 General Motors Diesel Locomotives

Brief Introduction

YE3 4503-4 is a paramount example of a three-phase induction motor. Engineered with meticulously optimized electromagnetic topology, this robust 900kW asynchronous motor fundamentally achieves significant torque density enhancement through carefully implemented proprietary rotor slot geometry. Its characteristically engineered 3-pole configuration reliably delivers consistent 1490rpm operational stability under dynamically variable loads, effectively minimizing critical speed deviation to strictly maintained <0.8% levels during transient operating states.

The comprehensively designed stator core strategically utilizes domain-refined silicon steel laminations, systematically reducing harmonic iron losses by approximately 18% versus conventional industry-standard designs. Integrated thermal management architecture professionally employs axial-radial hybrid ventilation (IC411), consistently maintaining essential winding temperature rise at ≤75K within specified 40°C ambient environmental conditions.

Precision-engineered dynamic balancing at standardized G2.5 grade operationally ensures controlled vibration levels below measurable 1.8mm/s at full rated load capacity. Strategically configured dual-voltage compatibility (660V/50Hz & 60Hz) broadly enables seamless global deployment without requiring operational derating considerations. The motor's structurally extended service intervals demonstrably exceed 20,000 hours through corrosion-inhibited bearing housings and comprehensively sealed IP55-rated terminal boxes.

Main Technical Parameters

Why choose Simo Brand YE3 series of Motor?

The YE3 Series LV Motor has a high-strength cast iron frame, so it is very strong and has a longer service life. Anti-corrosion copper wire coils are not only more powerful but also have thermal protection, so they are safer to operate. The copper wires are evenly arranged, so they are not easy to deform even if the motor runs for a long time. The bearings have high torque and good responsiveness, stable output, and lower noise. In addition, the smaller size and energy-saving characteristics make it more popular.
