I bought the 3V version and a 12V version and they are the same. They have very low torque. Running these at 3V for some robot wheels may be fine, but if you actually need to move anything with a little bit of weight good luck. (Couldn't slowly spin a Raz Pi5 and a web cam even at the 16-30 RPM range). Review: Okay - It’s super slow, slower than I thought. It was okay for my art project. ## Features - 【Imported Steel Plate】: After precision machining of 7 kinds of lathes, complete with four secondary auxiliary processes, high precision and customizable. - 【Three-layer Copper Plate】: It has good wear resistance, high temperature resistance and vibration resistance through continuous stamping with precision molds. - 【Processing Technology】: M0.15 micro module gear, clock gear technology, after six processing, high precision, good reliability, can guarantee stability under high life. - 【High Temperature Resistance】: High quality black plastic material, double-riveted riveting to prevent falling off at high speed. - 【Greartisan Gurantee】: We only offer high quality motors!

I bought the 3V version and a 12V version and they are the same. They have very low torque. Running these at 3V for some robot wheels may be fine, but if you actually need to move anything with a little bit of weight good luck. (Couldn't slowly spin a Raz Pi5 and a web cam even at the 16-30 RPM range). ### ⭐⭐ Okay *by M***A on 18 May 2023* It’s super slow, slower than I thought. It was okay for my art project. ### ⭐ Torque much lower than specificed *by J***J on 4 February 2024* This motor does not provide anywhere near the amount of torque listed in the datasheet. If torque is important in your application, do not believe these specs. ## Frequently Bought Together - Greartisan DC 12V 27RPM Worm N20 High Torque Speed Reduction Motor with Metal Gearbox Motor for DIY RC Toys - Greartisan DC 12V 78RPM N20 High Torque Speed Reduction Motor with Metal Gearbox Motor for DIY RC Toys - DC Brush 6V Mini Gear Motor, Micro Turbo Worm Geared Motor 1218GE‑N20 Reduction Geared Motor(DC 3V 30RPM) --- ## 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.tn/products/369853686-dc-12v-27rpm-worm-n20-high-torque-speed-reduction-motor](https://www.desertcart.tn/products/369853686-dc-12v-27rpm-worm-n20-high-torque-speed-reduction-motor) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-09*
