Where do you find a driver with 3.2 VDC anyway? **Q: does it work with MB450A Driver?** A: Yes, that is the driver I use with thi s motor. **Q: What is the max RPM?** A: I'm not sure. Steppers are more usually used for precise movements than for speed, and the maximum speed most mostly reflects the maximum frequency and minimum microstep ratio of the driver. I doubt it exceeds 1000 rpm, if that high. **Q: I am planning on using this to move 100 lbs down a rack pinion track while supporting the weight with bearing carriages on rails. Will this do that?** A: You need to know your desired maximum acceleration, static and dynamic friction and gear ratio. Or find some way of estimating it from similar applications you can find data for, or ask on reddit :) ## Frequently Bought Together - STEPPERONLINE CNC Stepper Motor Nema 23 Bipolar 2.8A 269oz.in/1.9Nm 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.pt/products/51579525-stepperonline-nema-23-bipolar-cnc-stepper-motor-2-8a-7](https://www.desertcart.pt/products/51579525-stepperonline-nema-23-bipolar-cnc-stepper-motor-2-8a-7) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-23*
