This motor has quiet operation, small volume and high speed, and the rear end of the motor is reinforced with a cooling fan, which can be safely worked for a long time. The motor is equipped with ER11 extension rod and collet, which supports engraving wood/plastic/acrylic/ pvc/pcb/carbon fiber/density board and other materials. Can also be replaced with ER16 extension rods and collets if needed. The function of the line is equivalent to a switch, and the output voltage cannot be output when it is disconnected. As for the positive and negative wiring of the motor and the power supply, you can connect it at will. Because the motor supports reverse rotation, if you need the motor to rotate forward, just replace the interface. Note This power regulator supports both 110V and 220V, If users need 110V, please just adjust the power supply to 110V. Spindle Motor Mount Applicable to:300w 400w 500w spindle motor Diameter: 52mm Material: Cast aluminum Cast aluminium clamp is much heavier than aluminium profile clamp. This product has hardness, strong impact resistance, high hardness and strong antioxidant activity. Review: Poor packaging No bits - This thing is poorly packaged, clamp is all banged up and it did not come with the 10pc engraving bits. Also the clamp is way too loose, it just slides right off the spindle. There's no instructions, they should at least mark the positive and negative connections. The power supply was just wrapped in seran wrap. The spindle chuck sticks out too far and doesn't want to budge, it should be pushed in further for better performance. I don't know how anyone is supposed to change the chuck. The chuck needs to be seated further into the shaft, but I don't want to hammer it in. It's a loud spindle for 800w. Louder than my 1200w plunge router. It has small connectors on the spindle. We'll see how it performs. Review: Works well - cut soft aluminum with ease - The first unit I got was bad and after speaking with customer service I got a replacement unit. This unit works well and fit correctly into that CNC. You can cut wood and even metal (do it slowly). It comes with some carving bits to get you started. ## Features - 【Supports Reverse Rotation】As for the positive and negative wiring of the motor and the power supply, you can connect it at will.

Make sure the application you need it for is low torque. even though 800 watt is around i1 horse the torque might not be there for you. I can stop the spindle with my hand. **Q: Weight of spindle by itself?** A: 0.97KG（2.14IB） ## Customer Reviews ### ⭐ Poor packaging No bits *by F***N on November 20, 2022* This thing is poorly packaged, clamp is all banged up and it did not come with the 10pc engraving bits.

This unit works well and fit correctly into that CNC. You can cut wood and even metal (do it slowly). It comes with some carving bits to get you started. ### ⭐⭐⭐⭐ Good Unit, runs a little warm *by D***. on August 4, 2025* I bought this spindle motor to use as a tool post spindle on my lathe. The unit performs well and the runout is minimal. My only concern ( and the reason I'm not giving it 5 stars) is that the unit gets pretty hot when running. I'm concerned that over time, this could cause issues. The motor control unis works pretty well, i haven't experienced any issues with it yet. I think for a small cnc machine, thin could make a decent spindle ## Frequently Bought Together - RATTMMOTOR 800W Spindle Motor Kit, 0.8KW 110V ER11 20000RPM 0.79NM Air Cooled DC Spindle Motor+Mach3 Fuction Motor Speed Controller Power Supply Converter AC110V/220V+52mm Mount Clamp for CNC Machine - Genmitsu 15PCS ER11 Precision Spring Collet Set for CNC Engraving Milling Lathe Chuck Tool, 1.0mm-7.0mm & 1/4", 1/8" - Genmitsu 40pcs End Mills CNC Router Bits, 1/8" Shank CNC Cutter Milling Carving Bit Set Including 2-Flute Flat Nose & Ball Nose, Nano Blue Coat & Titanium Coat, MC40A --- ## 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.vn/products/439757374-rattmmotor-800w-spindle-motor-kit-0-8kw-110v-er11-20000rpm](https://www.desertcart.vn/products/439757374-rattmmotor-800w-spindle-motor-kit-0-8kw-110v-er11-20000rpm) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-06*
