Looking for 3.4V 2.8A stepper** A: Coil voltage is 3.4V, the driving voltage is 24-48V. **Q: Do you also provide the screws that can be used to mount the stepper motor?** A: Sorry, we don't provide screws for the mount currently. **Q: Can i vary the steps of travel with an external pot input on this controller?** A: No. You question us confusing since this is a motor not a controller. This motor has a fixed step of 1.8 degrees you can’t change that from the controller. Not sure what you’re trying to do but you may want to look into a servo motor **Q: Can an encoder be attached to the back of the motor?** A: There are no features on the back of the motor that would allow the mounting of an encoder. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked perfect *by D***R on November 18, 2024* Used it to put auto bed feed on my Grizzly lathe. Good for the money and did the job well. ### ⭐⭐⭐⭐⭐ high quality *by S***M on September 19, 2025* very good ### ⭐⭐⭐⭐ Solid motor with good reputation *by T***. on December 22, 2017* 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. ## Frequently Bought Together - STEPPERONLINE Nema 23 CNC Stepper Motor 2.8A 178.4oz.in/1.26Nm CNC Stepping Motor DIY CNC Mill - 42 57 Stepper Motor Driver Controller Integrated Board Forward/Reverse Pulse Speed Angle Control Module PLC Serial Communication - STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-Step Resolutions for Nema 17 and 23 Stepper Motor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/11833859-stepperonline-nema-23-cnc-stepper-motor-2-8a-175-6oz](https://www.desertcart.co.za/products/11833859-stepperonline-nema-23-cnc-stepper-motor-2-8a-175-6oz) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-18*
