replacement x stepper motor help

[andy_con]

Turns out I need a new stepper motor on my triac, when under any sort of load even light it's stalling.

I don't want to replace the drive card or stepper housing can anyone recommend a replacement?

I do have an urgent job but that's out the window now

Hi Andy, is the fault more than just the drive pin.

[andy_con]

Sadly it is yes.

With just a light bit of pressure on the cog it's stalling so it needs to be replaced

[angel-tech]

is it ok to call you

[andy_con]

It's proving very hard to get a suitable replacement, current shaft is 9.5mm all New nema 34's are 12-13mm

Can anyone help, does anyone have a triac stepper spare?

Need one urgent

If I get a bigger shaft then the cogg/pulley won't fit

As I don't know the spec of the current strippers in the triac at the moment it's very to buy a new one.

Anyone got any thoughts on if this is a suitable replacement

Measurement wise it looks the same as current

Did you ever get this sorted out?

I'm in the process of converting a 1985 (green) triac to mach3 and my x-axis motor is bust.

yeah x motor replaced, I found a plate that did a pretty much identical stepper.

also replaced bearings on the x table
