CNC Spindle Motor 7.5 kW, 24000 RPM, 380 V, 800 Hz Water Cooled
The 7.5 kW Water-Cooled Spindle Motor is an elite industrial solution engineered for the most demanding CNC applications. Unlike standard motors, this unit features a robust 4-pole architecture delivering a massive 5.76 Nm of torque, ensuring stable performance during heavy-duty material removal. Operating at a high frequency of 800 Hz to reach 24,000 RPM, it provides the perfect balance of speed and power for thick stone carving, granite profiling, and deep metal engraving. The integrated water-cooling system maintains optimal thermal stability across its 26.5 kg frame, while the premium P4 bearing configuration (7008 & 7005) ensures ultra-smooth rotation. With an industrial-standard ER32 collet system, it supports large-diameter tooling up to 20mm, making it the primary choice for heavy industrial machining centers.

Technical FAQ & Operational Guide
Why does this 7.5 kW spindle use a 4-pole design?
A 4-pole design provides significantly higher torque (5.76 Nm) compared to standard 2-pole motors. This is essential for maintaining RPM stability when cutting through very hard materials like granite or thick metals.
What kind of VFD do I need for this motor?
You need a high-frequency Variable Frequency Drive (VFD) rated for at least 7.5 kW that supports a maximum output frequency of 800 Hz and 380V 3-phase input.
Can I use smaller tools with this ER32 spindle?
Yes, while ER32 can hold large tools up to 20mm, you can use collets to hold shanks as small as 2mm for more detailed engraving work.
