 CUSTOMER FEEDBACK

 How to Choose a 1.5KW Air Cooled CNC Spindle Motor

Choose this 1.5KW ER11 air cooled spindle motor if your CNC router needs higher cutting power than a 500W or 0.8KW spindle, but still requires a compact 65mm body and simple air-cooled installation. For light engraving and small projects, 0.8KW may be enough. For more frequent milling, deeper cutting or small workshop production, 1.5KW is usually a stronger and more practical choice.

• Best for: wood, acrylic, MDF, plastic, PCB and light aluminum/brass engraving.

• Machine fit: desktop CNC routers and small-format CNC engraving machines with a 65mm spindle mount.

• Control requirement: use a compatible 400Hz VFD for speed regulation.

• Maintenance advantage: air cooling avoids water pumps, water tubes and coolant circulation.
