2.2KW Water Cooled Spindle Motor ER20 + 3HP 2.2KW Variable Frequency Drive VFD Inverter for CNC Engraving Router ,Efficient Performance

Dynamic Balance Design:Unlike other milling spindle motors, ours use innovative & advanced dynamic balancing technology The distinct advantages are low noise upgraded efficiency & extended service life Powerful Bearing:Upgraded bearings have two main advantages of superior durability antirust performance. Greatly- improved high-speed core brings higher efficiency than the past. Anti-rust Material:The use of acid-proof materials makes the CNC router spindle motor more & sturdy The metal casing significantly improves cooling efficiency faster dissipates heat High Concentricity & Precision:With high accuracy concentricity our bearings are much superior to other manufacturers on the market. One-time molding design brings more excellent precision to the CNC spindle mount. Application Fields:Water-cooled motors mainly match with engraving machines or frequency converters, and commonly applied materials such as wood, stone, mold & metal etc
