2 Nail Motor
This is a simple homemade electric motor that uses two flat head nails glued together as the rotor shaft. The idea by sMartcreations2010 of using a standard steel hex nut to attach permanent magnets to the rotor shaft worked great. Here is one of sMartcreations videos that shows the steel hex nut rotor idea that I used on my motor: https://www.youtube.com/watch?v=G2F35DiNGu0
Ludic Science did a replication of my motor using screws for the bearings. He and I do similar work and he posts excellent ‘How To’ videos. https://www.youtube.com/watch?v=2BZqDTCFDk4.
