Heavy Duty CNC Spindle Motor for Precision Milling Work
✔️ 3.5kW 12000RPM 380V AC Drive w/ Steel Housing & Fan

This heavy duty spindle motor delivers steady high speed rotation for CNC routing and milling tasks. You will normally mount it on desktop machining centers or router tables that require stable 12000RPM output. The solid steel housing handles vibration while the built in air flow system prevents overheating during long production runs. Sold as a single unit ready for straight wiring hookups.

✅ Cast alloy steel frame for zero deflection
✅ 3.5kW continuous power at 12000RPM max speed
✅ Direct 380V three phase AC connection setup
✅ Enhanced airflow design prevents thermal buildup

💡 What keeps a high RPM spindle running smooth through heavy cutting loads?
A balanced rotor and tight tolerances are the main reasons this setup outlasts cheap knockoffs.
- Dynamic weight distribution cuts lateral wobble so you make cleaner passes
- Less shake transfers stress to other parts and keeps your bearings fresh longer
- Raw horsepower at top speed helps chew through hardwood and soft metals fast
- Handy clearance around the mounting base gives you room to wrench and adjust on site
