CNC Spindle Motor 7.5 kW, 18000 RPM, 380V Air-Cooled Square ER32
The 7.5 kW Air-Cooled Square Spindle Motor is a robust industrial solution designed for substantial CNC applications that require significant cutting force and mechanical stability. Engineered with a square body profile, this motor offers a larger mounting surface to minimize vibration during intensive material removal. Delivering a consistent 3.58 Nm of torque at a peak speed of 18,000 RPM, it is tailored for CNC router manufacturers, pattern making, and large-scale wood carving. The 380V motor operates at a stable 300 Hz frequency and is equipped with a premium P4 grade bearing configuration (2x 7008 & 2x 7004) to handle high radial loads. With a 17.2 kg architecture and an ER32 collet system supporting tools up to 20mm, this spindle provides the industrial-grade performance required for demanding machining environments where air cooling is preferred.

Technical FAQ & Operational Guide
What is the advantage of a square body design for a 7.5kW spindle?
The square body provides a larger, flatter mounting surface than round spindles. This significantly improves the mechanical connection to the machine headstock, reducing vibration during heavy-duty cutting and ensuring a superior surface finish.
Is any external cooling needed for this motor?
No, this model is fully air-cooled. It features a built-in fan system designed to maintain an optimal operating temperature, making it a lower-maintenance alternative to water-cooled models in industrial environments.
Which tools can I use with the ER32 collet?
The ER32 system is a standard industrial interface that supports tool shanks from 2mm up to 20mm. This versatility allows you to use everything from fine engraving bits to large material removal cutters.
