Hi guys, has anyone rewired a stepper.
I have a triple stack nema 34 stepper manufactured in the 80's, which seems to be breaking down and loses direction and stalls regularly.
I've swapped drivers and tried the same type of motor on the existing driver, so it's definitely the motor.
I've also replaced the original wiring which looked a bit rough.
i've stripped it and tried to make sure there's no crap inside it, and it looks as though the existing insulation on the coils is failing in places. I've also noticed faint traces of rust forming between the core laminations in one or two places.
Any ideas, it would be a shame to just replace this stepper motor.
