STEPPERONLINE NEMA 17 Stepper Motor (Economy Geared Stepper Motor) Alloy Steel Mounting Bracket ST-M1

If you have one of their Geared stepper motors, you need a bracket like this - either to mount directly and/or use as a template. very sturdy and up to specs.

Fits both the standard stepper and the one with the gearbox perfectly, no issues

It fits the economy gear motor perfectly, with absolutely no play once it's bolted in. It's well-dimensioned, not too heavy despite its steel construction, and provides enough space under the motor and gearbox to hold a nut.

This was an impulse purchase after I placed an order for a matching stepper motor, but I was not paying attention to the slot direction. i don't really understand why most of these have slots going parallel to an attached motor shaft. usually any pulley can provide an adjustment it that direction, but if the slots are perpendicular then you can use the slots for belt tensioning.

I am posting the first photo in case it might be helpful for somebody else. I purchased this unit intending to use it with a device I invented to measure a person's eyes 8 or more feet away (see second photo). I couldn't fit it into the design of this product. I ended up taking another approach and returned this device.

Definitely sturdy, it's a very accurate fit for common geared/planetary nema 17's and will also fit a naked nema 17 just as well.

This part is accurately made and fits a NEMA 17 perfectly. It is a welcome replacement for the poor quality mounting I received for the Z axis motor in my Velleman K8200 kit which only used two holes along 1 edge of the motor. The only reason for 4 rather than 5 stars is somewhat dodgy weld quality, not that it should affect useability.

Very solid mount for stepper motors. Does not bend at all. Rigid and hefty. I like the provision for geared steppers with the smaller inner holes and works for both regular stepper Nema17-sized stepper and its geared versions.
