Wish I had an answer, but at least I'm not THAT guy. **Q: How many RPMs will the motor run before the torque drops in half?** A: The torque is highest at a slow 10 RPM. The torque drops linearly at the RPM increase. It starts to skip pulses because of low torque at about 200 RPM. I had to add a 100 tooth to 36 tooth xml timing pulleys to increase the torque. **Q: Where can I get a gear that works with this 10mm shaft? Most of those I've seen are in standard, not metric units.** A: I've had luck finding pulleys on EBay. I'm not sure about gears but it would be worth a shot if you haven't already looked. Also you could buy something to fit on a 3/8in shaft and drill it out to 10mm. **Q: What is the maximum power output in Watts? I’m sure it’s higher than the 3W they have listed.** A: Hello, The power is calculated as: P = V *I* # of coils active, or equivalently P = I^2*R* # of coils active For instance, if only one coil is active, P=4.2^2*0.9*1 = 15.87 watts If two coils are active, such as when the motor is holding a position, then the power doubles, which comes down to 31.75 watts. Hope this helps, Hector ## Customer Reviews ### ⭐⭐⭐⭐⭐ this moter is good *by L***O on 25 September 2020* fitted well works fine good buy ### ⭐⭐⭐⭐⭐ Review *by G***X on 29 December 2025* Moteur costaud, câbles bien assez longs. C'est du classique et il fait parfaitement son travail. ### ⭐⭐⭐⭐⭐ Review *by S***E on 22 February 2025* used these for a rail system and an arduino build that required a good 50lbs of lift across two motors. These don't disappoint. They can heat up, so I set the stay current to 50% and they still hold steady but stay cool. Good motor. ## Frequently Bought Together - STEPPERONLINE High Torque Nema 23 CNC Stepper Motor 114mm 425oz.in/3Nm CNC Mill Lathe Router - STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-Step Resolutions for Nema 17 and 23 Stepper Motor - STEPPERONLINE NEMA 23 Stepper Motor (Economy Geared Stepper Motor) Alloy Steel Mounting Bracket ST-M2 --- ## 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.com.kw/products/52325269-stepperonline-nema-23-stepper-motor-3-nm-4-2-4](https://www.desertcart.com.kw/products/52325269-stepperonline-nema-23-stepper-motor-3-nm-4-2-4) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-20*
