I scratched my head for a while trying to come up with a quick, easy, and cheap enclosure. I was pretty close to welding something up out of aluminum, but I decided that was too much work. I'm not in the enclosure making business after all! A trip to Menards netted me a nice Square D NEMA 3R (outdoor) main lug panel board. For less than $25. I saved the box lugs and ground bar and threw out the rest. How can you beat a $25 enclosure?!?
Inside this box will be a 56 volt DC power supply, servo controller, and some sort of controller for commanding the servo. The big transforer is a 48 VAC 4 amp beast. To the right of it is a bridge rectifier. Not shown is a ~900uF capacitor. The emergency stop switch came from a scrapped Wintech machine (thanks Steve!). At the top you can see a BCD selector. I picked this up in Taiwan for < $1. This and a PIC will be used to set the indexing angle. Or at least that is the plan for now.
