Grandad’s Emoji Magnet Motor
This is a replication of a motor by Grandad where he used ‘Emoji magnets’ on the rotor. The magnets are weak and heavy and he had difficulty getting his to run. I was able to get mine to run and it was a fun project.
Here is Grandad’s 1st video of the motor: https://www.youtube.com/watch?v=tcpxBtj6-Eo
Here is his 2nd video where he reconfigured the motor and got it to run: https://www.youtube.com/watch?v=8MC8WxjbRMc&list=RDCMUCCDUFabVc3g52M0t77JwSBA&index=2
On my motor all four magnets are in repulsion to the drive coil. I used a loose fitting sewing needle as the rotor shaft. The rotor is 3d printed PLA plastic.
