They're likely not suitable for heavy-duty tasks like cutting aluminum or metal but they work well on wood and other lighter materials. I'm not pushing them too hard, so I can't speak to their performance under high-stress conditions. One important thing to note is that there’s no wiring diagram or documentation included with this purchase. You’ll need to do some research online or rely on your own experience to get everything set up. Specifically, make sure the REV/FOR (reverse/forward) connection is properly wired—without it, the motor won't run. Review: Quick delivery (9 days from order to having it in my hands) and surprisingly quiet. - I needed a spindle for a small cnc I'm making and I didn't want to jump to a 500w one. other spindles under 200w were ugly or non ER collet. arrived quickly and works very well. Would like it if they included the necessary 5.1K potentiometer for the AIN control or a clear guide on using the PWM but given the price which includes the BLDC driver and aluminum mounting bracket, it's a very good deal for anyone planning to do PCB, wood and very small scale aluminum machining. ## Features - 【Package Include】1x 104W Brushless square spindle motor ER8 ;1x Brushless spindle motor driver;1x Spindle Motor Bracket - 【Parameters of Spindle Motor】① Output Power: 104W; Voltage: 24V DC; Load current:1.35 Amps Max.; Load speed: 10800±rpm; Rated speed: 9000±rpm. ② Back EMF constant: 2.2V KPRM; Collet: ER8; Torque Constant: 0.021N.m/A; Rated torque: 0.11N.m; Phase to phase-resistance: 0.12Ohms. - 【Parameters of Motor Driver】CW & CCW Control; Speed control mode: 0-5V Analog mode and three-phase full bridge, PWM mode; Supply voltage: 24V; Supply current: Minimum 5A. - 【Advantages】The most direct change of this brushless spindle motor driver is that there is no spark from brush motor, it greatly reduces the interference of the spark to the remote control radio. With high integration and high reliability. - 【Features】① With the over-current protection measures, it can immediately turn off the output when overloaded and protect the motor in time. ②High speed, high anti-interference ability; No brushand low interference; Low noise, low heat and the reduced friction during work, it can make the brushless spindle motor runs smoothly. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08CMHPJ3S | | Best Sellers Rank | #635,896 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #652 in Electrical Motor Controls | | Brand | RATTMMOTOR | | Brand Name | RATTMMOTOR | | Customer Reviews | 4.0 out of 5 stars 18 Reviews | | Horsepower | 104 watts | | Item Dimensions W x H | 1.65"W x 5.71"H | | Manufacturer | RTM | | Material | Aluminum | | Material Type | Aluminum | | Model | JK42BLS04-10 | | Part Number | JK42BLS04-10 | | Product Dimensions | 1.65"W x 5.71"H | | Shaft Diameter | 8 millimeters | | Speed | 10800 rpm | | UPC | 619191200511 | | Voltage | 24 volts, 5 volts | ## Product Details - **Brand:** RATTMMOTOR - **Horsepower:** 104 watts - **Product Dimensions:** 1.65"W x 5.71"H - **Speed:** 10800 rpm - **Voltage:** 24 volts, 5 volts ## Images ![10800RPM 104W Air Cooled Spindle Motor 42mm ER8+Driver - Image 1](https://m.media-amazon.com/images/I/71UxSLULLhL.jpg) ![10800RPM 104W Air Cooled Spindle Motor 42mm ER8+Driver - Image 2](https://m.media-amazon.com/images/I/81zxIXbR3wL.jpg) ![10800RPM 104W Air Cooled Spindle Motor 42mm ER8+Driver - Image 3](https://m.media-amazon.com/images/I/71GG7eRU1tL.jpg) ![10800RPM 104W Air Cooled Spindle Motor 42mm ER8+Driver - Image 4](https://m.media-amazon.com/images/I/71kY6aISkvL.jpg) ![10800RPM 104W Air Cooled Spindle Motor 42mm ER8+Driver - Image 5](https://m.media-amazon.com/images/I/81rSuaQ9xrL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ They're likely not suitable for heavy-duty tasks like cutting aluminum or metal. *by T***O on July 15, 2025* I bought a few of these for my smaller multi-heads cnc setup, and so far, the motors run very quietly.

This device rarely shows up on an Amazon search for CNC spindles. It is hard to find. It needs an additional circuit diagram. ## Frequently Bought Together - RATTMMOTOR 24V DC Brushless Spindle Motor 10800RPM 104W Air Cooled Spindle Motor 42mm ER8+BLDC Spindle Motor Driver Controller 5A+Spindle Motor Mount Bracket for CNC Router Milling Machine - 9Pcs Collet ER8 CNC Engraving Chuck Machine Milling Lathe Tool Tap Chuck Lathe Tool Workholding for CNC Milling Lathe --- ## 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.hr/products/227418879-10800rpm-104w-air-cooled-spindle-motor-42mm-er8-driver](https://www.desertcart.hr/products/227418879-10800rpm-104w-air-cooled-spindle-motor-42mm-er8-driver) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-09*
