Signs you May Need a Motor Rewind:
If you have been informed that your electric motor requires rewinding, it means that the coils have been damaged, shorted, or grounded in some way. There are numerous underlying issues that lead to motor failures, which usually manifest themselves as insulation failures or grounded/shorted coils. Insulation failures may occur in several forms, such as shorted turn-to-turn or phase-to-phase windings, coil-to-coil, or grounding at the slot’s edge. These problems may be caused by contamination, abrasion, voltage surges, the machine’s age, or vibration. Thermal deterioration is another common cause of motor insulation failures, resulting from poor connections in the motor terminal, high currents in the stator due to a locked rotor, excessive load demands that surpass the motor’s rating, or excessive reversals and starts.
Some signs that a motor may need to be rewound include:
- The motor is making unusual noises or vibrations
- The motor is overheating
- The motor is drawing more current than usual
- The motor is producing less power than it should be
- The motor is failing to start or is starting slowly
- The motor is emitting a burning smell or smoke
If any of these signs are present, it is important to have the motor inspected by one of our professional motor rewind technicians to determine if rewinding is necessary.
Common Motor Issues
Numerous underlying issues lead to motor failures, from short circuits to insulation breakdowns, we tackle all causes of winding failures, using high-quality new wire and insulation resistance techniques to restore efficiency. Here are common issues motors face:
Insulation Failures
Insulation failures may occur in several forms, such as shorted turn-to-turn or phase-to-phase windings, coil-to-coil, or grounding at the slot’s edge. These problems may be caused by contamination, abrasion, voltage surges, the machine’s age, or vibration.
Thermal Degradation
Thermal degradation is another cause of motor failures, resulting from poor connections in the motor terminal, causing high currents in the stator due to a locked rotor which results in excessive load demands that surpass the motor’s rating, or excessive reversals and starts, which will cause the material to overheat and fail.
Mechanical Wear
Issues, like damaged motor coils or worn bearings, can severely impact motor function. Our repair services include everything from rewinding to complete rebuilds, ensuring your motor runs smoothly.
Electrical Problems
Faulty windings, phase issues, and core damage can all lead to reduced motor efficiency. Our technicians utilize the best practices in the industry to ensure a successful rewind every time.

FAQ's
- What is a motor rewind? → Motor rewinding is a process of replacing the copper wire coils and insulation inside an electric motor’s stator or rotor. This process is typically done to restore the motor’s functionality after it has experienced damage or wear.
- When is Motor Rewinding necessary? → Motor rewinding is necessary when an electric motor’s coils or insulation become damaged, worn, or fail. This can result in decreased performance, increased energy consumption, or complete motor failure. Rewinding the motor can restore its performance and functionality and is often a more cost-effective solution than replacing the entire motor.
- How long does motor rewinding take? → The time required for motor rewinding can vary depending on the size and complexity of the motor, as well as the extent of the damage. Typically, though, the process can take anywhere from a few days to several weeks to complete. One of our professional motor rewind technicians can provide you a more accurate estimation after they have assessed the condition of the motor.
- Can any type of motor be rewound? → Most types of electric motors can be rewound, including AC motors, DC motors, and servo motors. However, the rewinding process can be more complex for some types of motors, such as those with multiple winding layers or specialized insulation requirements. It is important to consult with a professional motor rewinding service provider to determine if a specific motor can be rewound.
- Is it better to rewind a motor or replace it with a brand new motor? → Whether it is better to rewind a motor or replace it depends on several factors, including the extent of the damage, the age of the motor, and the cost of a replacement motor. In some cases, rewinding a motor can be a cost-effective way to extend its lifespan and restore its functionality. That being said though, if the motor is significantly damaged or outdated, it may be more cost-effective to replace it with a newer, more efficient model. One of our professional motor service providers can provide guidance on the best course of action for your specific motor.
