5.5kW Spindle Motor 380V ER25 24000 RPM Water Cooled
✔️ 5.5kW 380V ER25 24000 125mm 4.9" x 350mm 13.78"

This handy 5.5kW spindle motor spins up to 24,000 RPM via 380V power, delivering solid torque for carving dense wood, cutting aluminum sheets, or handling deep grooves in stone blanks. It bolts straight onto standard CNC router beds and pairs excellent with a variable frequency drive so you can punch out exact speeds for whatever material you're working on.

✅ 125mm (4.9") diameter housing slips right into tight CNC router frames without needing extra clearance ✅ ER25 dynamic balancing nut grips tooling dead tight with less than 0.005mm runout for clean edges ✅ Water-cooling loop dumps heat fast so the motor stays chill during marathon carving sessions ✅ Copper rotor inside a stainless steel shell knocks down vibration and keeps things whisper quiet ✅ Four hardened bearings shoulder heavy side loads while the shaft whizzes up to maximum speed ✅ 4-port aviation plug locks in U, V, W power lines plus a grounded pin to stop electrical mess ✅ Rated for 400Hz drive inputs so you can push the amps and keep pace with aggressive feed rates

💡 What phase voltage and frequency drive setup does a 5.5kW water-cooled CNC spindle require? Here is the lay of the land on wiring this rig up so it runs slick and lasts for years. - You gotta hook a 380V three-phase line to the U, V, W terminals on the aviation connector so the shaft spins the right way and pulls clean current. - Tying it to a 400Hz variable frequency feed ensures the drive can modulate frequency smoothly to hit the sweet spot in the torque curve for tough cuts. - Sticking that fourth pin to ground drains stray voltage off the chassis and keeps your drive logic from going crazy during heavy loads. - Keeping water flowing at a steady rate seals the shaft lip and flushes hot spots off the bearings so the internals never cook themselves.
