THE ART OF ELECTRIC MOTOR REWINDING: BRINGING YOUR MOTOR BACK TO LIFE

Electric motors are the workhorses of the industry, powering everything from factory assembly lines to everyday household appliances. However, with time and wear, even the most robust motor can experience performance decline or complete failure. This is where electric motor rewinding steps in, offering a cost-effective and sustainable solution to extend the lifespan of your motor.

Key aspects of professional electric motor rewinding include:

Restoring electrical and mechanical performance: Aged or damaged windings are removed and replaced with new, precision-installed windings to return the motor to optimal operating condition.
Supporting long-term energy efficiency: Certified rewind practices help maintain or restore motor efficiency, contributing to lower operational energy costs.
Contributing to sustainability goals: Rewinding extends the life of the existing motor frame and core, reducing material waste and avoiding the need for full motor replacement.
Facilitating responsible asset management: Rewinding plays a vital role in preventative maintenance programs, helping organizations manage capital equipment over its full lifecycle.

WHAT IS ELECTRIC MOTOR REWINDING?

Motor rewinding is the process of meticulously replacing the damaged or aged electrical windings within an electric motor. These windings, typically made of copper wire, are responsible for generating the magnetic field that causes the motor shaft to rotate. Over time, factors like overheating, overloading, or simple wear and tear can degrade the insulation on the windings, leading to decreased efficiency, increased vibration, or complete motor failure.

Rewinding involves meticulously disassembling the motor, removing the old windings, and carefully installing new ones. This process requires skilled technicians with a deep understanding of motor design, electrical principles, and proper winding techniques. Here's a closer look at the key steps involved in electric motor rewinding:

Evaluation and diagnosis: The first step involves a thorough inspection of the motor to identify the cause of failure and determine the feasibility of rewinding. Technicians will assess the condition of the stator core, bearings, and other components to ensure a successful rewind.
Disassembly: The motor is carefully disassembled, following a specific sequence to avoid damaging any components. This may involve removing the end bells, rotor shaft, and existing windings.
Cleaning and core loss testing: The stator core, the heart of the motor, is meticulously cleaned to remove any debris or contaminants that could affect performance. Core loss testing is performed to ensure the core itself remains efficient.
Winding preparation: Based on the original motor specifications and desired performance characteristics, new windings are prepared. This involves selecting the appropriate wire gauge, insulation type, and winding configuration.
Coil winding: Skilled technicians meticulously wind the new coils onto the stator core, ensuring proper spacing, tension, and connection points. This step requires precision and attention to detail to achieve optimal performance.
Varnishing and curing: After winding, the coils are coated with a special varnish that provides insulation, protects from moisture, and improves heat dissipation. The varnish is then cured using a controlled heating process.
Quality control testing: Once reassembled, the motor undergoes rigorous testing to ensure proper functionality, electrical safety, and adherence to original specifications. This may involve vibration analysis, load testing, and insulation resistance testing.
Painting and final assembly: The rewound motor is painted to provide a fresh, protective finish. Finally, the motor is reassembled, ensuring proper alignment and torque on all components.

IDENTIFYING REPAIR NEEDS EARLY

Condition monitoring plays a key role in determining when an electric motor requires service. Some of the techniques used include:

Vibration analysis: Increased vibration can indicate bearing wear, imbalance, or misalignment.
Thermography: Thermal imaging can reveal hot spots caused by electrical faults or insulation breakdown.
Motor current signature analysis: Analyzing electrical signals helps identify developing mechanical or electrical problems.
Periodic insulation resistance testing: This test tracks insulation condition and helps predict winding failure.

When properly implemented, these techniques allow maintenance teams to plan electric motor rewind and repair in Brockville proactively, rather than responding to unexpected failures.

WHEN TO REWIND VS. REPLACE

Not all motor failures require a rewind. In some cases, replacing a motor may be more cost-effective. The decision depends on factors such as:

Motor size and specialization: Large, specialized, or obsolete motors are generally more economical to rewind.
Motor efficiency: If a very old motor is inefficient compared to modern models, replacement may offer better long-term value.
Lead time: If a replacement motor is on long backorder, rewind can restore service much faster.
Total repair cost: If mechanical repairs combined with the rewind approach or exceed the new motor cost, replacement may be preferable.

Hewitt (Brockville) Ltd. provides clients with clear cost and performance comparisons to support informed decision-making.

PLANNING FOR SPARES AND SERVICE ROTATION

For critical operations, maintaining a serviceable spare motor reduces downtime risk. We advise clients on:

Identifying motors where spares are cost-justified.
