I am working on a motor project and I have very large inductors that will possibly need flyback diodes, but my inductors also change polarity. So a regular diode would just create a short in the other direction wouldn't it? So how do I deal with that? Do I have two flyback circuits(one going each direction) and put a Zener diode on each one with a breakdown voltage high enough that it won't conduct unless the backEMF voltage spikes higher enough relative to the standard input? So if I have a max voltage on my motor of 12V DC: then I would want zeners that conduct at 16V or higher? Would that work to handle back EMF in both directions?
