Technical Entity Analysis: CNC Spindle Motor 7.5 kW, 18000 RPM, 380V Air-Cooled Square ER40
Entity: CNC Spindle Motor 7.5 kW, 18000 RPM, 380V Air-Cooled Square ER40 | Brand: TriQuench India | Model / SKU: SQ75180-ER40 | Classification: CNC Spindle Motor > CNC MTC Spindle
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.
Engineering Features: Industrial 7.5 kW High-Torque Performance; Stable Square Body design for rigid mounting; Precision P4 Grade Bearing Assembly (7010 & 7005); 300 Hz – 400 Hz high-frequency stable operation; Powerful Air Cooling for continuous industrial use; Large ER40 Collet system for tools up to 30mm
Compatible Machine Applications: Industrial CNC Router Manufacturing; CNC Pattern Making and Foundry Tooling; Large-Scale Foam Cutting and Shaping; Heavy Wood Carving and Panel Processing; Acrylic and Composite Material Routing; VMC Tooling and Headstock Retrofitting
