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:

1. 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.

2. Precision Disassembly & Component Evaluation:

   • Systematic disassembly of stator, rotor, bearings, and housing.

   • Non-destructive inspection (NDT) of core laminations and rotor bars.

3. Component Reconditioning & Replacement:

   • Rewinding or re-insulating stator windings.

   • Bearing replacement with precision-aligned installation.

   • Shaft repair or balancing as required.

4. Advanced Cleaning & Surface Treatment:

   • Removal of carbon deposits, dust, and oxidation.

   • Application of industrial-grade varnish and insulation treatment.

5. 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.
