Important Details That You Should Know About Electric Motor Rewinding

By Mandy Cross


Whenever an electric motor fails or starts to show some signs that may lead to its deterioration, the engineers find a way of addressing the issue. They may agree on repairing it at first or decide on replacing it at once depending on the damage. They can also restore it by a process called rewinding. It is economically viable to rewind the motor than replacing. However, some people think that electric motor rewinding may decrease its efficiency.

The materials used in the process can affect the effectiveness of the motors. For example, if you strip a coil from a stator core at high temperatures before winding back, electrical features found on the base may change. This will lead to losses of iron, and it may lower efficiency. As far as an engineer can reverse the electric motor according to its specifications, it is possible to arrive at the initial performance levels.

Whenever your motor has failed, you should first seek a qualified and an experienced engineer. Most electric motors have failed because they are attended by some people who have no vast experience, therefore, limiting their expertise to one model. The engineer should be able to work on different motors at any given time.

The materials used during the rewinding also have an effect on thermal dissipation. Some of the materials are quality resins and insulating tapes of a high standard. To ensure that you will get the best operation while installing motors, automated designs should be designed when forming the coils. Most of the experts in this industry have concurred that you can improve the reliability and also enhance uptime of the motors. However, this shall lower the operating costs.

A client should be made to understand that the repair may have some positive and adverse effects on the motors. The customer has to realize that even after paying for the services; the engine may not perform according to his expectation. An engineer should ensure that the customer fully understands that before he can start the rewinding it

Most of the companies cannot wait for days to replace their motors, and this has forced them to train their engineers on rewinding of motors. In most of these companies the heavy machines used are of age and finding their replacement is a challenge. Every motor has different specifications, and it brings on a challenge when looking for a replacement. It is time-saving to rewind them and increase their efficiency.

In situations where the failed motors have no replacement because of old versions or unavailability in the market, an engineer can try different options. For instance, some manufacturers do not fill stator slots by use of wires. In such a case the engineer can improve its efficiency by keeping the same number of turns and increasing wire size.

Moreover, when your motor is about to undergo rewinding, you make sure that the engineer knows of your expectations. You may come up with an agreement on how the rewinding will be done. You can agree on inspecting the core of the stator before the engineer can strip the windings. Old bearings can be replaced with new ones as a measure to increase efficiency.
