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 :) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Test Unit for Shark HD5 (HD510) *by on Reviewed in the United States July 7, 2022* I love my Shark HD5 CNC (HD510) but before I buy a 4th axis, which I would build or buy a generic one since NW is way over priced, I wanted to make sure I had good control over the 4th axis card I added and could find and jog what I believe to be the right motor. This worked. Searching posts I found enough info to select this one and wire a DB9 to the flying leads. This motor worked great as a test unit and I will now buy my 4th axis from Amazon. I can throw this motor into my spare parts bin or retrofit the lathe I like to accept this motor if the one that comes with is not quite right for my driver card. You assume all risk if you go this route but once you understand the important specifications you need, this would be a good way to test things out. There is some info I can't find on the Shark so I will have to experiment with things like gear ratio, and if have to either change the position of the physical motor or change it in software, but this helped with the learning curve. ### ⭐⭐⭐⭐⭐ Quality motors, great precision... *by on Reviewed in the United States July 15, 2018* These are great motors and they are very strong. I purchased 7 of these and I use them to build a prototype where these motors have to pivot an assembly by 87 degrees. They are quiet and while I had to write code to start them at low speed and increase the speed as they are moving, and also need them to release their hold every time a move is complete, they are always precise and don't miss a step. I use the STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC to drive them and I feed it with a 24 Volt power supply. At this voltage, they pull about 1/2 an amp when holding. However, I should mention that one of them has pinched wires close to the motor but I take it this was a shipping issue and don't think I should reduce any stars for it.Also note that there is usefull information in a PDF described as "User Manual" under the heading "Technical Specification" on the Amazon Product PageIf the power they offer is enough for your application, these are definetely recommended for whatever you are going to do with them. ### ⭐⭐⭐⭐⭐ Perfect motor for a heavy 3D printer z-axis *by on Reviewed in the United States August 28, 2021* I didn’t want multiple steppers for my z-axis as they can get out of sync. My platform is fairly heavy (large and tightened to eliminate backlash). This stepper combined with StepperOnline’s DM542T driver, provides speed, consistency, high torque, and excellent precision. Very happy with the system. ## 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.com.ar/products/11150157-stepperonline-cnc-stepper-motor-nema-23-bipolar-2-8a-269oz](https://www.desertcart.com.ar/products/11150157-stepperonline-cnc-stepper-motor-nema-23-bipolar-2-8a-269oz) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-06*
