Electric Motor Rewinding Can Be A Challenging DIY Undertaking

By Philip Collins


One can hardly imagine a world without electrical motors. They make air conditioners possible, they circulate the water in a swimming pool and they power vacuum cleaners. The list of uses for these devices are endless. Most people will be surprised if they take the trouble to count the number they have in and around their homes. They can be expensive to replace or repair, however. Luckily, DIY enthusiasts in Phoenix can consider electric motor rewinding themselves.

Not every enthusiastic DIY man should tackle such a project, however. Patience, close attention to detail and concentration is required. Even small mistakes will ensure that the device will not work. Therefore those that do not enjoy projects that require a great deal of attention to the smallest details will be better off to seek the services of a professional to repair the device.

Those that are not daunted should proceed to remove the housing. This will show the stator, the windings and the armature. Once the housing is removed, taking a series of detailed photographs or video is strongly recommended. When it comes to recreating the windings, patterns and connections this will be of great help. A rewind must be done according to the original patterns or it will not work.

Next, the wire must be taken from the brushing pads. The tabs should be disturbed as little as possible in order to completely remove the wire. Once this is done the coils in the wind can be cut free. It is vital to record the number of winds in every coil and to write it down because they will have to be rebuilt to that exact configuration.

The insulation lining the stator should be carefully inspected for damage. Where necessary, it should be replaced with the same insulation material or ordinary insulation tape. At this stage the stator or armature can be winded. It is recommended that the same type of wire with the same gauge is used. The windings should be precisely the same as it was originally and it should be done with a single long wire.

A length of wire, long enough to reach the first tab should be left free at the end of the first winding. This is where both the first and the last winding will be attached. It is important to make sure that their is good contact. Some of the insulation can be removed to ensure a solid contact. As the work progresses, the wire can be crimped to keep it in place.

Next, the end of the last winding and the loose wire from the first winding can be connected. After making sure that no wire connected to the tabs are touching. Thereafter it is simply a matter of assembling the housing again and to test the device. If it is not performing as expected it is best to ask a professional to examine the work done.

During all DIY projects, and especially ones involving electricity, safety precautions should be maintained at all times. Each year numerous people are injured or maimed simply because they did not follow basic safety rules. Children should be prohibited from handling potentially dangerous tools.
