Our AC Motor Overhaul Service is an engineered solution designed to restore and optimize the operational performance of alternating current (AC) motors across a broad range of industrial applications. Over time, electrical and mechanical degradation — including insulation breakdown, bearing wear, rotor imbalance, and winding faults — can compromise motor efficiency and reliability. Overhaul restores the motor to near-new condition while ensuring compliance with engineering performance standards.
Technical Scope of AC Motor Overhaul:
Comprehensive Diagnostic Inspection:
Electrical testing: insulation resistance (IR), winding resistance, surge test, and core loss evaluation.
Mechanical assessment: bearing condition, shaft alignment, rotor dynamics, and structural integrity.
Precision Disassembly & Component Evaluation:
Systematic disassembly of stator, rotor, bearings, and housing.
Non-destructive inspection (NDT) of core laminations and rotor bars.
Component Reconditioning & Replacement:
Rewinding or re-insulating stator windings.
Bearing replacement with precision-aligned installation.
Shaft repair or balancing as required.
Advanced Cleaning & Surface Treatment:
Removal of carbon deposits, dust, and oxidation.
Application of industrial-grade varnish and insulation treatment.
Final Assembly & Performance Verification:
Torque and vibration testing.
Electrical performance verification to meet or exceed original specifications.
Key Benefits:
Restored efficiency and torque performance.
Extended operational lifespan and reduced downtime.
Compliance with industry performance and safety standards.
Detailed overhaul report for quality assurance.
Applications:
Suitable for a wide range of industrial motors including pumps, compressors, HVAC systems, conveyor systems, and manufacturing equipment.
