1.5KW ER11 Air Cooled Spindle Motor 65mm Shaft 110V AC For CNC Woodworking With Four Angular Contact Bearings 24000RPM Inverter Ready Requires VFD Or Inverter For Safe Operation And Precise Milling Workhorse

1.5kW ER11 Spindle, Single with Four Angular Bearings
✔️ 1.5kW ER11 air-cooled spindle, 65mm shaft, 110V, 24000RPM, VFD ready

This high-power spindle motor is built for CNC routers and milling machines, ideal for wood, plastic, and light metal work. It runs on 110V AC and needs a VFD or inverter for safe operation and precise speed control. Four angular contact bearings extend spindle life and stabilize high-speed milling. Hefty yet compact, it weighs about 3.0 kg and uses a 65mm shaft for versatile mounting in compact CNC setups.

✅ 110V AC input works with standard shop mains
✅ 65mm spindle shaft diameter for compact CNC installations
✅ Four angular contact bearings boost life and rigidity
✅ Inverter-ready wiring with proper ground reference
✅ 24000 RPM max speed for fast material removal
✅ Weight around 3.0 kg for easy mounting
