Urja Engineering

Core Service

Motor Rewinding

End-to-end AC and DC motor rewinding services for industrial motors, pumps, compressors, and rotating machinery across all voltage and power ratings.

Service Overview

Precision Rewinding for Maximum Motor Life

Our motor rewinding services cover the complete lifecycle from diagnostic assessment and winding removal, to precision coil winding, insulation treatment, and final testing. We restore motors to original OEM performance specifications or better.

With a team of certified motor winding technicians and advanced equipment, we follow IS standards and IEC specifications, ensuring every rewound motor is safe, efficient, and field-ready.

Scope of Work

Technical Capabilities

We handle rewinding of motors across a wide range of frame sizes, power ratings, and applications — from fractional horsepower units to large industrial drives.

Power Ratings

Rewinding capability from 0.5 HP fractional motors up to 1000 HP large industrial drives and generators.

Motor Types

Squirrel cage, slip ring, TEFC, ODP, explosion-proof, submersible pump motors, and servo motors.

Insulation Class

Rewinding to Class B, F, and H insulation standards using high-grade enamel-coated magnet wire and VPI treatment.

Voltage Ratings

LT motors up to 1.1 kV and HT motors up to 11 kV, with full winding data documentation and as-built reports.

The Urja Advantage

Execution Excellence

Expert Winding Team

Our rewinding technicians hold decades of combined experience with motors across diverse industrial sectors including petrochemical, textiles, water utilities, and cement plants.

Uncompromising Safety

VPI vacuum pressure impregnation treatment, megger insulation resistance testing, and hi-pot testing ensure zero-failure motor performance post-rewinding.

Timely Delivery

Rigorous workflow management and in-house coil forming shop ensure express turnaround without compromising on quality — minimising your plant downtime.

/// Methodology

Our Installation Process

01

Inspection & Diagnosis

Complete motor teardown, winding checks, insulation testing, and failure analysis with a detailed diagnostic report.

02

Coil Winding & Forming

Precision winding using OEM data or reverse-engineered specs, with premium magnet wire and durable slot insulation.

03

VPI Impregnation

Vacuum Pressure Impregnation with Class F/H resin for enhanced moisture resistance, mechanical strength, and thermal durability.

04

Testing & Handover

Motor rewinding carries inherent electrical and mechanical risks. We operate with a zero-compromise policy on safety every motor undergoes mandatory pre and post-testing as per IS 325 and IEC 60034 standards.

/// Safety First

Compliance & Safety Standards

Electrical installations carry inherent risks. We operate with a zero-compromise policy on safety, ensuring every project meets strict regulatory and statutory requirements.

IS / IEC Compliance

Rewinding to IS 325 & IEC 60034 standards with test records.

Mandatory PPE

Arc flash suits, insulated gloves, and safety barriers used throughout testing.

Hi-Pot & Megger Testing

Mandatory insulation and high-potential testing before and after rewinding.

Documentation

Winding data sheets, test reports, and as-built records with every motor.
