I've made myself a prize wheel consisting of the following parts:
- Main wheel: Galvanized sheet metal plate (d=250 mm), with a fidget spinner glued on the back. Loosely attached to an M8 threaded axle.
- Logo wheel: Galvanized sheet metal plate (d=90 mm), with a M8 nut glued on the back. Attached to the same M8 threaded axle.
See video here:
This works nicely. However, instead of having to spin the wheel myself I thought it might be fun to have a DC motor handling this. The only problem is I don't know how.
I'd like the wheel to function in the same manner as the one I've already made. That is:
- The main wheel should get going when I press a NO (normally open) switch.
- It should keep on spinning after the switch is released (engine stops).
- The logo wheel should stay static.
I'm going to make another base for the wheel, with a flapper that will slow the wheel down and indicate the winning number. I have access to a sheet metal workshop, so I plan on building it using galvanized metal once I get an idea on how this thing should be designed.
Any help is greatly appreciated!
