See my latest experiments and behind-the-scenes footage!
Lego motors are unfortunately only rated for around 9 volts. But I’ve always wondered how much you can overvolt small motors before they burn out. And what chaos we can bring by chucking 120 volts through a small motor. In this video, rather than destroying my Lego motors, let's instead make our own motor using some neodymium magnets, copper wire, and of course, Lego!
We’ll try a couple different rotor designs, some different commutator designs, and we’ll try to feed them as much power as possible from a power supply. Can we get to 120 volts without melting or burning out?
