How to Get Cheap Magnet Wire

Introduction: How to Get Cheap Magnet Wire

This instructable is how to get some cheap magnet wire from a motor. You will get from 2m to about 10m depending on what motor you are using.

Step 1: Opening the Motor

Lift up the 2 clips on either side of the motor and lift off the top with the contacts. You can know take out the axial with the wire on.(Optional: you can take out the magnets in the motor by removing the U shaped clip and then taking out the magnets.)

Step 2: Unwind the Wire

Unsolder or break of the contacts and then unwind the wire from each of the three poles.

    Ebay sellers weren't any cheaper either ! They all wanted around $25 a LB. If you have a specific supplier that is at least below $10 LB then please tell us who with a LINK if possible. I don't know if links are allowed or not.

    Does anyone know of an actual lower cost magnet wire ? Copper wire is $3.26 /LB but Magnet wire is about $25 / LB. The varnish or enamel isn't worth $22 a pound so it is WAY OVERPRICED ! Yes I know you can get it from old electronics but if you need even 1 LB it takes a long time and a lot of work to get. And I need 5 - 10 LBs of 12-14 guage magnet wire. Does anyone know of a supplier that is at least 5-6 a LB, DOUBLE the price of copper ? Selling it for 7 times the price (25 /3.26 = 7.66) is rediculous ! Large transformers are usually VARNISHED and can't be unwound without messing up the enamel insulation, same for TV deflection coils.

     When you try to re-use cheap magnet wire, the brittle ceramic coating cracks, both when you remove it, and when you re-wind it. Whatever you're building has a 90% chance of having shorts in the coil.

    it is best to desolder the wire from the comm because you can reuse the arm and make a way faster motor.

    I got a good 20 feet of wire (about that size) from a hard drive motor, and after you get to smash the disk with a hammer!

    i have a motor like that but it came out of the trunk of a 93 lincoln town car

    I think they only cost about 50p which I find is cheaper. I also find them for free inside old electronics sometimes.

    Why not dismantle something otherwise useless, like a transformer from a broken electrical? L
