Improve efficiency and extend the life of your electric motor with an Electric Motor Rewind.
Electric motors are critical components in a vast range of industrial, commercial, and residential applications. From driving conveyor belts in factories to powering HVAC systems, electric motors keep the wheels of modern life turning. But like any mechanical component, electric motors can wear down over time. One of the most effective ways to extend their lifespan and restore peak performance is through electric motor rewinds.
What is an Electric Motor Rewind?
An electric motor rewind is a specialised service that involves removing the motor’s old or damaged windings (the wire coils that create magnetic fields to make the motor spin) and replacing them with new, insulated wire. This process restores the motor to its original or near-original performance level.
Motor rewinds can be performed on a wide variety of electric motors, including AC motors, DC motors, servo motors, and more. Whether your motor is in heavy industrial machinery or smaller commercial applications, a professional motor rewind can restore its function and efficiency.
Why Do Electric Motors Need Rewinding?
Electric motors are built to last, but over time, the insulation on the windings can break down due to factors such as heat, vibration, moisture, or electrical surges. As the insulation degrades, it can lead to short circuits, reduced performance, and even motor failure.
Symptoms indicating that your electric motor may need rewinding:
Overheating: If the motor consistently runs hotter than usual, it could be a sign of internal damage to the windings.
Unusual Noise: A grinding or humming noise may indicate that the motor is under strain due to failing components.
Reduced Efficiency: A motor that isn’t producing the same power output or is using more energy than usual might need a rewind.
Frequent Tripping: If your motor trips circuit breakers regularly, it could be due to electrical faults in the windings.
The Rewinding Process
A motor rewind is a detailed and technical process, typically performed by trained professionals in specialised workshops. Here’s a breakdown of the steps involved:
Dismantling the Motor: The motor is first carefully disassembled, and the rotor, stator, and other key components are inspected.
Stripping Old Windings: The old windings are removed, and the slots where the new wire will go are thoroughly cleaned.
New Windings: New copper or aluminium wire is carefully rewound onto the stator. This step requires precision to ensure the windings are done correctly, so the motor runs smoothly.
Insulation and Varnishing: Once rewound, the windings are insulated to prevent short circuits and ensure durability. The motor is then varnished to further protect against environmental factors like moisture and dust.
Reassembly and Testing: After the windings are complete, the motor is reassembled and rigorously tested to ensure it operates efficiently and safely.
Benefits of Motor Rewinds
- Cost Savings: Rewinding a motor is often much more affordable than purchasing a new motor, especially for large, industrial-sized motors.
- Improved Efficiency: A well-executed motor rewind can restore the motor’s performance to near-original levels, often improving energy efficiency.
- Extended Lifespan: Rewinding can extend the operational life of your motor, allowing you to get more use from your existing equipment.
- Reduced Downtime: For businesses reliant on machinery, a motor rewind can reduce downtime compared to waiting for a replacement motor, especially if the motor is custom-built or has a long lead time.
Choosing a Trusted Rewind Service
