The spindle motor's aviation plug marked with number 1, 2, 3, 4. Number 1, 2, 3 port are connected separately with inverter's port U, V, W. Number 4 is the ground wire, no wiring is required. ## Features - ✅【How to Connect The Spindle Motor】The spindle motor's aviation plug marked with number 1, 2, 3, 4. Number 1, 2, 3 port are connected with inverter's port U, V, W respectively. Number 4 is the ground wire, no wiring is required. - ✅【Simple Introduction】This is a 110V-2.2KW air-cooled 15A Φ 80x195mm spindle motor come with a ER20 nut and collet. Frequency is 400HZ, 0.003--0.005 accuracy and runout off is less than 0.01mm. It is mainly suitable for non-metallic engraving,such as wood carving/engraving machine, advertisement engraving machine, cnc machine. - ✅【Cooling Method】- Good heat dissipation effect by adopting fan cooling method, without connecting to water pump and water pipe, it's more convenient and trouble-saving and can be used directly by connecting with the inverter. - ✅【Rotation Accuracy】- The rotor has high precision because of precision steel ball retainer, and high temperature resistant grease lubrication method, all of which ensures the rotation accuracy and low noise of the spindle during high-speed grinding. - ✅【Material & Configure】- The spindle has fine workmanship, 3 bearings, stainless steel body and dustproof design make the spindle more durable. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0BTY7BYYP | | Best Sellers Rank | #859,507 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #165 in Power Milling Machines #422 in Power Tool Combo Kits | | Brand Name | RATTMMOTOR | | Customer Reviews | 3.4 3.4 out of 5 stars (7) 3.4 out of 5 stars | | Manufacturer | ChangSheng | | Material Type | Iron | | Number Of Items | 1 | | Part Number | RTM-GDZ80F-2.2 | | Speed | 24000 rpm | | Upc | 754193412040 | ## Product Details - **Brand:** RATTMMOTOR - **Speed:** 24000 RPM - **Voltage:** 110 Volts - **Horsepower:** 2.2 Kilowatts - **Material:** Iron ## Images ![RATTMMOTOR 2.2KW 110V Air Cooled CNC Spindle Motor ER20 24000RPM | 400HZ 3HP 15A 400HZ ER20 Spindle Milling Motor for CNC Router Engraving Machine - Image 1](https://m.media-amazon.com/images/I/61tLXgRR3RS.jpg) ## Questions & Answers **Q: Do you have more motor specs so the vfd can be properly setup as a reviewer has mentioned? or is the only specs what is listed on this ad?** A: I have not yet completed the project so I can't yet give any opinion. **Q: The product information stated the spindle weight 5.2lbs. I am not sure this is right. Does anyone know how much this spindle actually weigh?** A: Sorry, the weight is 5.27kg, not lbs **Q: does this come with a power supply?** A: No ir dos not. You need yo buy a VFD controller to drive it **Q: Can this motor be wired direct to 220v ac without a vfd controller? I only need 24,000 rpm.** A: Sorry, as I know now in the world no motor can be wired direct to 220v ac without a vfd controller ## Frequently Bought Together - RATTMMOTOR Air Cooled CNC Spindle Motor 110V 2.2KW 80MM 3HP 24000RPM 15A 400HZ ER20 Spindle Milling Motor for CNC Router Engraving Machine - 16AWG 1.5mm² Shielded Chain CNC Wire (12FT) UL2464 Tinned Copper Core Extreme Flexible 16 Gauge 4 Core Cable Electrical Wire for CNC Router Machine, CNC Spindle, Robot Arm,3D Printer,etc --- ## 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.us/products/516639588-rattmmotor-2-2kw-110v-air-cooled-cnc-spindle-motor-er20](https://www.desertcart.us/products/516639588-rattmmotor-2-2kw-110v-air-cooled-cnc-spindle-motor-er20) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-21*
