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. ## 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.kg/products/15385014-stepperonline-47-1-planetary-gearbox-nema-23-stepper-motor-2](https://www.desertcart.kg/products/15385014-stepperonline-47-1-planetary-gearbox-nema-23-stepper-motor-2) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-05*
