If you build these drivers I would appreciate price chopper application pdf if you left feedback in the comments section so we all may benefit from your experience. This is the schematic for my drive. This is the board layout I came up with.
I wasn’t planning on etching it, I only needed parts on a board. I print this out, tape it to a piece of board, drill it, put parts in, then solder them point to point. When I design stuff I keep in mind that I have to make it too so I try to design things I am capable of making. Making this is a little tricky but it can be done. It works too, and I know no one is going to rip my design off for commercial exploitation. Good luck making these in quantity! I made three and that was enough for me for a while.
Pop Quiz: Can anyone see what label is wrong with this? At least I think that one is right now. The main component of this circuit is the Toshiba TB6560AHQ Stepper Motor Driver IC. These are brilliant little chips. You don’t have to mess with surface mount, you can put a heatsink on it easily, they do everything you can possibly ask for with a hobby CNC stepper motor driver. The next part of note is the optical isolators.
