    Very good, thank you. So coil pairs are next to each other rather than outer and inner. That makes thing easier. One additional question. What might I expect to happen if my coils are out of phase? Meaning Coil 1 is connected +-, but coil 2 is connected -+? I have the data sheet of the motors but it doesn’t indicate which legs are in phase. I’ve seen some data sheets for motors that have a bar over one leg in each coil which I assumed meant if one was connect to positive the other had to be as well. I know with reversible motors saying one side is positive and the other negative doesn’t make much sense, but I don’t know how else to put it unless one leg is considered “prime” or something like that.

    Cheers
