Description
Product Overview
The RATTMMOTOR 2.2KW spindle motor is engineered for high‑performance CNC applications where speed, precision, and durability are paramount. Operating at 220 V and drawing only 6 A, this square‑shaped, air‑cooled unit reaches a maximum rotational speed of 24 000 RPM, making it ideal for rapid material removal and fine detail work. The motor incorporates a precision‑tapered ER20 collet with a runout of less than 0.01 mm, ensuring that the tool holder remains stable even at the highest speeds. Four high‑quality bearings support the spindle shaft, reducing vibration and extending service life. The motor’s frequency of 400 Hz provides a smooth power delivery that minimizes electrical noise and heat buildup, while the robust construction tolerates the demanding environments of woodworking, aluminum machining, glass cutting, and PVC engraving.

Usage
Designed for versatility, this spindle motor fits seamlessly into a wide range of CNC routers, engraving machines, and milling equipment. Whether you are cutting hardwood for furniture components, engraving intricate designs on acrylic sheets, or machining lightweight aluminum parts, the motor’s high speed and low runout deliver consistent results. The air‑cooled design eliminates the need for external water cooling systems, simplifying installation and reducing maintenance. Users should connect the U1, V1, and W1 terminals to the corresponding inverter outputs and supply 220 VAC to any two of the inverter’s R, S, or T terminals. Before powering up, manually rotate the spindle to verify free movement and ensure that the coolant circulation system is active to manage temperature during prolonged high‑speed operation.

FAQ
What type of materials can I machine with this spindle motor?
The motor is optimized for non‑metallic materials such as wood, aluminum, glass, and PVC. Its high speed and low runout make it suitable for detailed engraving and precise cutting tasks across these substrates.
How do I connect the motor to my CNC controller?
Connect the motor terminals U1, V1, and W1 to the corresponding inverter outputs. Then supply 220 VAC to any two of the inverter’s R, S, or T terminals. Refer to the wiring diagram included in the package for exact pin assignments.
Is additional cooling required for prolonged operation?
While the motor is air‑cooled, it is recommended to use a coolant circulation system during extended high‑speed runs. This helps dissipate heat generated by the spindle and maintains optimal performance.
Can I replace the collet if I need a different size?
Yes, the spindle features a standard ER20 taper, allowing you to swap out the collet for other ER20‑compatible sizes to accommodate a variety of tool shank diameters.
What warranty does the motor come with?
All RATTMMOTOR spindle motors are covered by a one‑year limited warranty that includes defects in materials and workmanship. Our support team is available to assist with any warranty claims or technical questions.
