Features of the ER16 1.5KW CNC Air Cooled Spindle Motor

The Zhong Hua Jiang Square ER16 1.5KW Air Cooled Spindle Motor Kit is engineered for stable CNC routing, engraving, and milling performance. It combines a precision ER16 collet system, matched VFD inverter, air-cooling structure, and practical installation accessories for professional and small workshop applications.

The kit includes the ER16 1.5KW air-cooled spindle motor, a matched VFD, 110V/220V compatible,  aviation/ power wires, wrenches, and often drill bits for immediate setup. Delivering 1.5KW power at speeds from 10,000-24,000 RPM with runout under 0.005mm, its four upgraded steel bearings extend lifespan up to 3x longer than standard models, while dynamic balance tech minimizes noise and vibration.

The air-cooled structure provides efficient heat dissipation without a water pump, making the spindle easier to install and maintain. It is suitable for compact CNC routers, desktop CNC machines, engraving machines, and light-duty CNC production lines working with wood, acrylic, PVC, MDF, plastics, PCB, aluminum, and brass.
