The 7.5 kW Air-Cooled Square Spindle Motor is a high-stability industrial powerhouse designed for substantial CNC tasks that demand significant cutting force and thermal reliability. Featuring a robust square body design for enhanced mounting rigidity, this motor delivers a high torque of 6.65 Nm, making it the primary choice for CNC pattern making, industrial foam cutting, and heavy wood carving. Operating at 18,000 RPM with a frequency range of 300 Hz – 400 Hz, it ensures efficient material removal across dense substrates. The spindle is equipped with a premium P4 bearing configuration (2x 7010 & 2x 7005) to handle high radial and axial loads, while the ER40 collet system supports large-diameter tools up to 30mm. At 30 kg, this 380V motor provides the mass and precision required for high-stability machining centers where water-cooling is not feasible.
