Hi,
I'm working on a project that uses electromagnets to turn a ring. There are three rings, and each uses 3 electromagnets, so I want to keep the circuit simple, and the parts count low. The rings each have 20 high power magnets around the edge. That is the "target" of the electromagnets.
The idea is to use a higher current on the electromagnet initially, then a lower current to hold the position.
I've created a schematic to illustrate the idea I had, but would appreciate and comments or suggestions.
Is the basic circuit idea the way to do this?
What size/value of capacitor should I use?
R1 is intended to liit the charge rate of the capacitor, What value should I use?
R2 is intended to limit the current through the coil. I was thinking of 220ohms?
Thanks!
