Three Undeniable Signs You Need Electric Motor Rewinding Services
In most cases, when an electric motor starts to deteriorate in terms of performance, most people rush to replace it by purchasing a new one. However, you can restore the optimal performance of the electric motor and extend its life span via electric motor rewinding services.
Electric motor rewinding is a three-step process that involves:
- Removing the damaged winding coils
- Installing new winding coils
- Insulating the new coils
One of the main reasons you should consider electric motor rewinding services instead of purchasing a new electric motor is the cost. Typically, electric motor rewinding costs a fraction of the price of a new motor. However, the rewinding services ensure that your electric motor runs as good as new.
With that said, here are three significant signs that indicate your electric motor needs rewinding services.
Clear Signs of Deterioration
Typically, most electric motors are durable. However, throughout their use, they get exposed to the elements. As a result, they are bound to start deteriorating at some point. Some of the most common signs of wear and tear (deterioration) include the presence of rust, moisture, and burns.
These signs may seem negligible at first, but whether you notice it or not, they contribute to your electric motor's poor performance. Thus, call a technician to check out why your electric motor is performing poorly. If they encounter any of the above signs of deterioration, they will likely recommend that you seek electric motor rewinding services.
During the rewinding service, the technician will replace the coils with rust or burn marks with new ones. Thus, these efforts will restore the electric motor's optimum performance.
Improper Winding Resistance
Another sign that indicates your electric motor could need rewinding services is when its winding resistance is low. You can find the optimum winding resistance of your electric motor listed on its nameplate or in documents provided by the manufacturer.
When your electric motor starts to deteriorate in performance, you should call a technician to measure the winding resistance. If the winding resistance measurements taken by the technician do not match with the optimum winding resistance, it could be that the motor has shorted coils.
Thus, it is essential to conduct an electric motor rewinding service, to replace the shorted coils and reinstate its performance.
Low Insulation Resistance
Most of the components in an electric motor are susceptible to heat. As such, if the electric motor has low insulation resistance, some components will be damaged by heat. As a result, you may experience a reduced level of performance from the electric motor when the components start to malfunction due to excess heat.
Unfortunately, low insulation resistance occurs naturally when the insulation wears out or becomes loose due to vibrations. Fortunately, the third step in electric motor rewinding services is re-insulation.
Overall, rewinding an electric motor can help reinstate adequate insulation resistance and restore your electric motor's performance. Contact an electric motor rewind service to learn more.
