Micro Amp Pulse Motor

by · Published · Updated

This is homemade electric motor that runs on 3 volts @ 150 micro amps. A simple two transistor circuit controls the firing of a very fine wire coil that pushes the magnet rotor around. I am studying more efficient motors like this that could run for years on two AA batteries.
