CNC Spindle Motor 4.5 kW, 18000 RPM, 380 V Air-Cooled Square
The 4.5 kW Air-Cooled Square Spindle Motor is a heavy-duty industrial solution engineered for high-performance CNC machining where power and thermal stability are paramount. Delivering a robust 2.27 Nm of torque at 18,000 RPM (300 Hz), this motor is designed for aggressive material removal in woodworking, pattern making, and foam processing. Its square profile enhances mounting rigidity and cooling surface area, making it a reliable choice for long-duration production cycles. Equipped with a premium P4 precision bearing configuration (2x 7008 & 2x 7002), it ensures minimal runout even under high radial loads. The inclusion of the ER32 collet system allows for a wide tool range from 2mm to 20mm, providing the versatility needed for diverse industrial routing tasks without the complexity of a water-cooling setup.
