Electric Motor Rewinding Can Be A Rewarding 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.

First, it is necessary to remove the housing in order to expose the armature, stator and windings. Experienced professional advise that detailed photographs be taken at this stage. When winding, the exact patterns and connections will have to be recreated and the photographs can be a big help in this regard. Even small mistakes can render the project a failure.

The next step is to carefully remove the wire from the brush pads and in the process, care should be taken not to bend the tabs more than absolutely necessary. Then the coils in the winding can be cut from the stator or the armature. In the process, the number of winds should be counted and recorded. Once the rewind is done, it will have to be exactly the same as the original.

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.

The end of the first winding should be left apart and it must be long enough to reach the first of the tabs. The final winding will also be connected at that specific point. The wire can be held in place with a crimping tool. Care should be taken, however, to make sure that the wire makes decent contact with the tab. If necessary, some of the insulating material can be taken out.

Once the winding is completed the wire from the first and last windings can be attached. No wire connected to the tabs should be touching each other. After this the housing can be reassembled and testing can take place. If, at this stage, the device does not work it may be better to get a professional to undertake the work rather than to start another attempt.

It is important to remember that electrical devices can be dangerous. Great caution should be exercised at all time, especially when testing the device. Children should not be allowed to become involved in such projects. In fact, they should not be allowed near the working area.
