motor shaft ?

[grahamshere]

Can a stepper motor shaft be replaced, mine some how broke off.is it hard too do if can be done? thanks. Graham

[ger21]

No, but it shouldn't have broken. I'd contact whoever you got it from and see if they'll replace it.

[grahamshere]

thanks Ger, not good news, I,m sure the warranty is over. Dam it's upsetting, was running so good. oh well thanks.

Were you running with a solid coupling?
If so, a slight misalignment will cause it.

Ya made them my self, similar to dumpster's couplings, guess they aren't very good, say Al, who carries steppers in Canada, BC preferably. do you Know? Graham

[Al_The_Man]

I don't know of many that carry anything in stock, but Electromate (Ont) have always been in the servo/stepper field.

I thought the shafts were just pressed into the core. Have been looking at a 34 frame motor and wondering about pressing it back so I can install a handwheel to the back side. The motor side is pretty long. As I got several for free, I'm thinkng about sacrificing one to a hydraulic press.

I found novacon which is in Ont.There a bit cheaper. Any way I was wondering if I reversed the motor, has dual shaft, and just reversed the set up in mach 3 would that work until I get a new motor? it,ll probable be 2 weeks before I get one from any were I'm guessing, cant wait that long. Graham

[Al_The_Man]

The reverse shaft should work, either motor connections or Mach set up to reverse.
In the mean time I would look at Oldham coupling or Stainless Helical.

Thanks Al, I,ll give it a shot and see about couplings, just a pain ordering on the net, and no one around here sell's them, I don't know whats up with Canada, no manufacturing here at all seems. what in mach 3 would I need to change?

[Al_The_Man]

Helical you can get from R.G. Shelley Ont.

Should just need to change Ports & Pins -> Motor Output -> Dir LowActive setting for the axis in question.
