CNC Spindle Motor 12 kW, 18000 RPM, 380 V Water Cooled
The 12 kW Water-Cooled Spindle Motor is a flagship industrial solution engineered for the most intensive metalworking and heavy-duty milling applications. This motor stands out with its robust 6-pole architecture, delivering a massive 6.5 Nm of torque—providing the superior 'grunt' required for aggressive material removal in steel, aluminum, and dense alloys. Operating at 18,000 RPM with a high-frequency input of 900 Hz, it strikes an optimal balance between rotational speed and sheer cutting power. The high-capacity water-cooling system ensures maximum thermal regulation across its 27 kg industrial frame, while the premium P4 bearing configuration (7008 & 7006) provides the rigidity needed for precision drilling and milling. Equipped with a versatile ER32 collet system, it supports large industrial tooling up to 20mm, making it the primary choice for heavy-duty CNC machining centers.

Technical FAQ & Operational Guide
What are the advantages of a 6-pole motor design for milling?
A 6-pole design significantly increases torque (6.5 Nm) compared to 2 or 4-pole motors. This provides more power at lower speeds, allowing the spindle to maintain RPM under the heavy resistance encountered during metal milling and large-diameter drilling.
What type of inverter is required for this 12kW spindle?
You will need a high-frequency Variable Frequency Drive (VFD) rated for at least 12kW (or 15HP) that supports a 900 Hz output frequency and 380V 3-phase input.
Is the cooling system adequate for 24/7 industrial use?
Yes, the high-flow water cooling system is specifically designed for continuous industrial duty cycles, maintaining internal temperatures and protecting the P4 grade bearings during prolonged operation.
