Default Direction of an AC motor revisited

Just wanted to get back to the group about this AC motor that was running
in reverse after being disassembled and then put back together. It turns
out that reversing the brushes did indeed reverse the direction of the
motor. We can't argue with success, but I still don't fully understand why
this is so. Can anyone please explain this to me? Thanks, Lenny


I don't have access to the growler any more but can't I use my Simpson? I'm
thinking that I should have continuity between each of two segments 180
degrees apart. Is that correct? Lenny


Sure, use the Simpson on low ohms, once you have located a winding's bars go
around and check each winding. Start with a winding with clean bar edges and
then move up to the burnt ones. If you find an open or hi resistance check
the crimp or soldering at those bars.
