Ultimate Mini Pulse Motor Throttling!!! ~ Transistor Motor Controller

Throttled between 150mA and 650mA with a 2VDC input. I had a great time building a playing with this project. Watch the complete construction and operation here: https://youtu.be/eSzVXSYhLmc

Smallest mini pulse motor on Youtube. I have yet to see one this small anywhere else on Youtube, what a great project!!!

This was a fun little science experiment to engineer a very small and compact pulse motor. I spent a fair amount of time looking around Youtube and as far as I can tell this is the smallest one out there. If I'm mistaken just let me know in the comments!

Pulse motors work mostly the like way their name sounds. Magnets attached to a rotor are repelled from a stationary coil (motoring coil) which is pulsed to allow new magnets to move into position. The pulsing action is generated from some type of sensor on the opposite side of the rotor that reacts when the magnets pass by it. Typically this sensing is done through induction with another coil, a reed relay or a hall effect sensor. I attempted the first two approaches in this video but due to the motors small size I only had success with the reed relay.

On future builds I will probably use a hall effect sensor as they are a little better suited for these types of applications. (I just didn't have any on hand when I started this build ;) )

Let me know what you think in the comments and if you have any questions be sure to ask. And don't forget to SUBSCRIBE!!!! The goal is to double the size of this channel in 2018!!!!
