Turning down the shaft of a stepper motor..

[John Hill]

I have a stepper motor that had a bent shaft so I turned it down from 3/8" to 5/16".



So, what do you think?

Think ???  Well, not something I try very often but here goes ...

Superior Electric Slo-Syn ??

Shorted connections to semi-lock the rotor while machining ??

Ex-IBM 5256 printer forms feed motor maybe ??

If so you should have saved yourself the trouble and asked me. One firm I worked for dumped 10 or so of them and I grabbed the motors seeing as they were being scrapped.
Still got some of 'em somewhere maybe..   I seem to remember they are 180 step/rev. rather than 200

Now to be told I'm absolutely wrong ... AGAIN ....

Edit  Even found one, picky att.

Got it in one!

Yes, 180 steps and an IBM sticker (different factory though).   This will drive the Z feed on my CNC router project,  the X and Y will be driven with Fisher and Paykel washing machine motors.

My motor does seem to be bigger having a 2.8A rating.
