STEPPERONLINENema 23 CNC Stepper Motor 2.8A 178.4oz.in/1.26Nm CNC Stepping Motor DIY CNC Mill

Used it to put auto bed feed on my Grizzly lathe. Good for the money and did the job well.

Very easy to control the motor with a microstep driver and Arduino Uno.

Worked like it should on mt rotary

Excellent quality motor. Keep in mind that this Nema 23 motor draws 2.8A per phase (two phase motor) so it should not be driven by small motor drivers. Follow the advice given in the "questions" section and pickup a motor driver that handles this beast. I picked up a few decent ones from ebay and love this thing. It has plenty of torque and speed for my application. I am looking into getting a tiny motor controller or a gshield.

Perfect fit on the Longmill CNC. Just requires some wire crimping/splicing expertise.

I normally pick these up over at open builds, but they were out of stock and the price hhttps://www.amazon.com/review/create-review/ref=cm_cr_dp_d_wr_but_top?ie=UTF8&channel=glance-detail&asin=B00PNEPF5Iere was very competitive. The Nema 23's are used pretty extensively in CNC applications, which is what I'm using mine for. Enough power for light aluminum at a decent speed.I gave this four stars instead of five as one out of the four I purchased was bad, and caused me to have to tear apart my machine to replace. I had to re-solder wires, etc. and caused some down time and headache. I think generally they are generically pretty reliable, but in my case I got a dud that was working intermittently. I would still recommend them, despite my little setback or a 25% failure rate.I will also add that the units that come from Open builds have a wire sheath to contain the four wires, and it makes for a nicer appearance. This particular unit does not have that. It's a little thing, but I like a clean appearance to my builds.

I use it for making jigs for woodworking and it always stops exactly at the steps I program it to. Never seen it skip a step.I’ve bought a few with a few spares but have yet never had to replace any.

The motor has a good torque if provided with appropriate power. (rating changed to 5 stars)OLD COMMENT :Torque at 12V is not impressive. (I think its < 1 N/m because it barely performs better than a nema 17 rated at 0.42 N/m)EDIT: the driver I use (A4988) has a voltage regulator with a screw allowing to increase the voltage. Doing so increased the torque significantly (and the heat production on the driver).So overall my previous comment on torque does not stand, since this was a matter of power supply/driver.
