Product Design and Construction Features
High-Rigidity Cast Iron Frame: Manufactured from high-tensile cast iron, providing high mechanical strength, structural stability, and superior resistance to industrial vibration.
Low-Loss Stator and Rotor Cores: Constructed with high-grade, cold-rolled silicon steel laminations to minimize electromagnetic hysteresis and eddy current losses.
Precision Die-Cast Rotor Structure: Integrated aluminum die-casting improves electrical conductivity and mechanical balancing, reducing operational vibration.
Class F Insulation System: Built with thermal-resistant winding insulation rated for Class F operating temperatures, operated within Class B thermal limits (80K) to extend motor operating life.
IP55 Sealed Enclosure: Protects internal windings and bearings against dust accumulation and water splash from any direction.
Motor Components and Functional Details
Shaft and Bearing System
Features a precision-machined cylindrical shaft extension (standard dimensioning) suitable for flexible direct couplings, belt drives, or gear connections. Outfitted with high-load industrial bearings for stable axial and radial load capacity.
IP55 Terminal Box Assembly
Top-mounted heavy-duty terminal box offering secure 6-pin connection blocks compatible with both Star (Y) and Delta (Δ) wiring setups. Fitted with sealed cable glands to keep out dust, moisture, and airborne contaminants.
IC411 External Fan Cooling Scheme
Employs a shaft-mounted external cooling fan inside a protective steel cowl, drawing ambient air across the housing cooling fins to ensure continuous thermal exchange during full-load operation.
Industrial Applications and Solutions
The YE4-132S2-2 motor provides efficient drive performance across a wide range of industrial equipment:
Chemical & Petrochemical: Drives process pumps, industrial agitators, continuous mixers, and specialized blowers.
Mining & Metallurgy: Powers auxiliary processing equipment, slurry pumps, and material handling systems.
Water & Wastewater Treatment: Drives municipal intake pumps, aeration blowers, and high-pressure filtration pumps.
General Manufacturing & OEM: Integrates into industrial machine tools, hydraulic power units, and continuous production line machinery.
Quality Control and Testing System
Every YE4 motor undergoes comprehensive factory testing before dispatch to ensure absolute compliance with international performance standards:
Raw Material Inspection: Full verification of copper wire insulation, core laminations, and casting integrity.
Stator Winding Testing: Surge withstand, insulation resistance, and high-voltage dielectric testing.
Rotor Balancing: Precision dynamic balancing to minimize mechanical vibration.
Performance Testing: No-load running test, full-load efficiency test, thermal rise measurement, and noise verification.
