Video --188.8.131.52 18:04, 11 September 2013 (UTC) Tips Practice on an old or inexpensive motor before you try working on an expensive one. Take great care to make each coil tight and precise for the best performance. Without the insulation, the pressure of the wire against the stator/armature posts can breach and/or possibly even grind away the insulating varnish on the wire, exposing the wire's channel of electricity, eventually posing an electrocution hazard and potentially even causing an electrical short. 7 Rewind the armature and/or stator using the same gauge and type of magnet wire that was on the original motor. Any other types of wire (floral, arts and crafts, hanging wire, etc) will not produce any spin in the motor at all and in fact has the potential to cause electrocution and even send you to the emergency room. For the best performance, try to match the original motors winding length as close as possible. Home Categories Home and Garden Home Improvements and Repairs Electrical Circuits and Devices Motors Generators and Transformers ArticleEditDiscuss Edit ArticleHow to Rewind an Electric Motor Community Q&A Electric motors are relatively simple mechanical devices, but rewinding the coils on a DC motor is a precise task that should only be undertaken by those who with experience in mechanical or electrical repair. For instance, if you are winding one post in a clockwise direction and you move onto the next post, you would wind that post in a counterclockwise direction. If its in good shape, you can put it back in place before beginning your rewind.
If you rewind one of those squirrel cage stators, especially one of those that has the coils that, looking through the center of the stator, resembles a rope circle, it is best to find a piece of wood as big as the inside of the original coils, or you can also use a Dremel to sand down a slightly oversized block or stick to the proper size, and wind the coils on that stick. You can replace burned or damaged insulation with similar material or insulating tape. About this wikiHow 777reviews Click a star to vote Click a star to vote Thanks for voting!

Before taking on the task of rewinding an electric motor, it is extremely advisable to get yourself a wire gauge so that you can measure the gauge of the wire used in the original windings.

Bend the tabs gently (and as little as possible) and completely remove the wire from the tabs before cutting the coils of the wind. Wiring in an armature without insulation can pose an even greater electrocution/electrical short hazard as centrifugal forces that occur while the armature is spinning are highly capable of causing uninsulated wire to rub against the posts, resulting in more severe erosion and loss of the varnish insulation. And then the next post is wound clockwise, after that, counterclockwise, and so forth. The coils must be insulated from the steel laminates at all times.
