Low Voltage Three Phase 4kW AC Motor

Title:

YE4-112M-2 Low Voltage Three Phase AC Motor

Brief Introduction

The YE4-112M-2 4kW AC motor features bidirectional thermal symmetry critical for reversible operation. Its axial-symmetric ventilation system employs radial-bladed fans (parallel to shaft axis) delivering identical airflow in both rotational directions. This AC motor undergoes rigorous validation via duct-blocking protocols to confirm uniform temperature rise profiles (±3°C deviation) during forward/reverse testing. Structural precision ensures:

Balanced internal ducting eliminating directional flow resistance

Isotropic heat dissipation from windings to frame

F-class insulation maintaining thermal headroom

For confined installations, the design mandates ≥150mm peripheral clearance to prevent ambient heat recirculation-mitigating asymmetric temperature distribution in obstructed spaces. Unlike unidirectional motors with angled blades, its symmetrical aerodynamics sustain rated efficiency without derating during rotation reversals. Manufacturing controls include laser-aligned fan shrouds and computational fluid dynamics (CFD)-optimized ribs. Continuous-duty validation under sealed-chamber simulations verifies <65°C winding rise at 40°C ambient, meeting IEC 60034-30 efficiency benchmarks. This 4kW AC motor guarantees consistent cooling integrity across reversing applications like conveyors or winches, where ventilation asymmetry historically caused hotspot failures.

Main Technical Parameters

Why choose Simo Brand YE4 series of Motor?

The YE4 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.
