Re: Stepper Dissasembly

Hi,

I understand your point of view, but I have to deal with situations
when "junk goes wrong".

I had someone (no one on this group) that hooked up and destroyed 6
drives in succession on a motor he had liberated from a dumpster. I
had him send me the offending motor and it had a shorted turn on one
phase. An ohmmeter wouldn't show it but an inductance bridge did.

One "free" motor and six dead drives.
