Pay attention to the dimensions the transmission on this one is bigger than the actual motor. Review: Great Motor - Great stepper motor. Plenty of torque for the job. I am using this to drive a conveyor belt with precise positional accuracy. I have sheared gears and keys before stripping anything internal to the motor. Obviously not water proof, so ensure you protect it from the elements. ## Features - Bipolar Stepper, Holding Torque: 40Nm ,Rated Current/phase : 2.8A - Gearbox Type: Planetary - Frame Size: 60 x 60mm / 2.36x 2.36" , Motor Length: 56mm / 2.20" ,Gearbox Length :72mm / 2.83" - 4-wires (Black, Green, Blue, Red) , Weight: 1.7kg ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00WAV322U | | Brand | STEPPERONLINE | | Brand Name | STEPPERONLINE | | Customer Reviews | 4.7 out of 5 stars 11 Reviews | | Item Weight | 1.7 Kilograms | | Item weight | 1.7 Kilograms | | Manufacturer | OSM Technology Co.,Ltd. | | Material | Metal | | Material Type | Metal | | Model | 23HS22-2804S-PG47 | | Model Name | gear | | Model name | gear | | Part Number | 23HS22-2804S-PG47 | | Speed | 2800 RPM | | UPC | 701056591893 | | Voltage | 48 Volts | ## Product Details - **Brand:** STEPPERONLINE - **Material:** Metal - **Model name:** gear - **Speed:** 2800 RPM - **Voltage:** 48 Volts ## Images ![STEPPERONLINE 47:1 Planetary Gearbox Nema 23 Stepper Motor 2.8A for DIY CNC Mill Lathe Router - Image 1](https://m.media-amazon.com/images/I/61l4blBF00L.jpg) ![STEPPERONLINE 47:1 Planetary Gearbox Nema 23 Stepper Motor 2.8A for DIY CNC Mill Lathe Router - Image 2](https://m.media-amazon.com/images/I/61Hrn1gVhXL.jpg) ![STEPPERONLINE 47:1 Planetary Gearbox Nema 23 Stepper Motor 2.8A for DIY CNC Mill Lathe Router - Image 3](https://m.media-amazon.com/images/I/41gbdtffEmL.jpg) ![STEPPERONLINE 47:1 Planetary Gearbox Nema 23 Stepper Motor 2.8A for DIY CNC Mill Lathe Router - Image 4](https://m.media-amazon.com/images/I/31cKfwDcIqL.jpg) ![STEPPERONLINE 47:1 Planetary Gearbox Nema 23 Stepper Motor 2.8A for DIY CNC Mill Lathe Router - Image 5](https://m.media-amazon.com/images/I/61N9GmKYZaL.jpg) ## Questions & Answers **Q: What is the maximum speed output of the gearbox?** A: The maximum speed output is about 25RPM. **Q: Is there a torque curve available for this motor?** A: Stepper motors definitely have torque curves. They are not constant torque. Planetary drives do not lock movement, they can be backdriven. Most likely the best torque performance will be had from this motor between 0 to 300 RPM. Other 2.8A motors I have (with published torque curves) produce about 100 oz. in. at 600 RPM. **Q: What types of voltage supplies would you apply to this motor? For example, a car battery.** A: 24Vdc is what i would recommend to keep the current down. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Big! *by D***S on 21 May 2024* Heavy duty, high quality hobby stepper. Pay attention to the dimensions the transmission on this one is bigger than the actual motor. ### ⭐⭐⭐⭐⭐ Great Motor *by T***D on 20 July 2025* Great stepper motor. Plenty of torque for the job. I am using this to drive a conveyor belt with precise positional accuracy. I have sheared gears and keys before stripping anything internal to the motor. Obviously not water proof, so ensure you protect it from the elements. ### ⭐⭐⭐⭐⭐ Small high torque/powerful motor *by M***K on 24 July 2018* Great small motor with a lot of power and was at a great price conpared to McMaster Carr. Haven't had a problem with the motor yet. ## Frequently Bought Together - STEPPERONLINE 47:1 Planetary Gearbox Nema 23 Stepper Motor 2.8A for DIY CNC Mill Lathe Router - 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.co.za/products/391166745-stepperonline-47-1-planetary-gearbox-nema-23-stepper-motor-2](https://www.desertcart.co.za/products/391166745-stepperonline-47-1-planetary-gearbox-nema-23-stepper-motor-2) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-12*
