Significant Information That You Must 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.

An engineer should be keen on the types of materials that he uses when rewinding faulty motors. Stator core should not be stripped of its coil when in high temperatures because these may lead to a change of electrical features. Among many other factors, this can lower its efficiency due to iron loss. Every engineer can reinstate a faulty motor to its previous status as long as he follows the specifications.

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.

Thermal dissipation is the most important characteristic of a motor and the materials used when rewinding should not have any effect on it. An engineer can try insulating tapes and resins. It is now common knowledge among engineers that enhancing reliability and uptime of electric motors is possible.

In most of the technical procedures, a customer should understand that the end result may vary. Before an engineer can start on rewinding the motors, the customer needs to understand that even after rewinding there may be chances where the motors can fail, especially if it had a serious problem. In such circumstances, you may not have a good outcome in spite of paying for the services.

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.

Some situations arise whereby you try looking up for a replacement, but you cannot find it at the dealers. In this case, the engineer can modify the motors by use of the available materials. In some motors, the slots in the stator are not filled with wires. If such a situation arises, the engineer can increase the size of the wire and ensure that there is an increment on turns in the motor.

When you submit your motors to the engineer, you should agree on all particulars that need to be changed for the motor to be efficient. Some of these items that can be modified include bearings, windings and any other that might be necessary. You can agree on the size of the wire with an objective increasing its efficiency.
