Three Phase Cage Induction Motor

Title:

YE3 225M-2 Three Phase Cage Induction Motor

Brief Introduction

Engineered to eliminate premature bearing failures, this YE3 225M-2 motor integrates 13 critical protection systems addressing root causes of overheating and acoustic anomalies in rotating assemblies.

Core Bearing Safeguards:

Contamination Defense: Sealed labyrinth barriers prevent particulate ingress during assembly/operation, while corrosion-resistant coatings protect against humid environments.

Precision Clearance Control: Optimized shaft-fit tolerances maintain operational clearance under thermal expansion, neutralizing eccentric magnetic forces.

Thermal-Stable Lubrication: Adaptive grease reservoirs with regulated circulation paths ensure optimal viscosity across temperature extremes (-30°C to +150°C).

Axial Current Isolation: Ceramic-coated end shields and insulated bearing seats disrupt shaft current pathways from VFD harmonics.

Manufacturing protocols include:
• Laser-aligned stator-rotor assemblies eliminate misalignment-induced axial loads
• Directional cooling fins enhance heat dissipation from bearing housings
• Pre-calibrated rotor slots minimize parasitic magnetic thrust
• Induction heating processes for controlled bearing installation

Validated under 500-hour accelerated load testing, the 225M-frame motor executes critical functions:

Dynamic load distribution across high-precision bearings prevents localized wear

Integrated moisture-drain channels expel degraded lubricant byproducts

Accessible resistance monitoring terminals detect early fluting damage

Speed Control Integration:

Pole-Changing Capability: Dual-winding configurations enable step-less ratio switching for discrete speed adjustments without external devices.

VFD-Ready Construction: Low-inductance windings minimize harmonic losses during inverter operation, supporting full PWM frequency conversion from rectification to filtered output stages.

Rotor Resistance Adaptation: Reinforced slip-ring assemblies facilitate external rheostat connections for torque-optimized slip regulation in winding applications.

Ideal for pumps, compressors, and high-inertia drives, it extends bearing service life by 40% through synchronized mechanical, electrical, and thermal protection systems.

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.
