RATTMMOTOR 500W Cooled Spindle Motor ER11 12to100VDC 0.5NM 12000RPM

Description

Product Overview

The RATTMMOTOR 500W spindle motor is engineered for high‑performance CNC applications, delivering a rapid 12,000 RPM speed and a solid 0.5 Nm torque. Its air‑cooled architecture utilizes a reinforced rear fan, ensuring continuous operation without overheating, even under demanding workloads. The motor operates across a flexible 12‑100 VDC voltage range, making it compatible with a variety of power supplies and controller boards. With a precision‑ground 52 mm spindle mount, the unit offers exceptional rigidity and minimal radial runout (0.01‑0.03 mm), translating to superior cutting accuracy and surface finish. The motor’s insulation resistance exceeds 2 MΩ and its dielectric strength is rated at 400 V, providing robust electrical safety. Designed for compact installations, the spindle’s overall dimensions are minimized while maintaining high power output, making it an ideal upgrade for both hobbyist and professional CNC routers.

Usage

This spindle motor excels in a wide range of machining environments. For woodworkers, it powers precise routing, carving, and drilling of solid wood, MDF, and plywood, delivering clean edges and reduced vibration. PCB manufacturers benefit from its high RPM capability for fine engraving and micro‑drilling, achieving tight tolerances on copper and substrate materials. The motor’s quiet operation makes it suitable for indoor workshops and educational labs where noise reduction is essential. Its broad voltage tolerance allows seamless integration with existing CNC controllers, whether powered by a dedicated DC supply or a variable‑frequency drive. Users can mount the motor on standard aluminium profiles or custom brackets, thanks to the universal ER11 collet system that accepts a variety of tool shank sizes. The motor’s durability and low maintenance requirements ensure long‑term reliability for continuous production runs.
