Zhong Hua Jiang ER11 65mm 1.5KW Water-Cooled Spindle Motor features an intelligent control system and is designed for simple, user-friendly operation, suitable for users of all skill levels.
This is a Φ65mm round water-cooled spindle motor with ER11 collet chuck. It delivers 1.5KW of power, supports 10000–24,000 RPM speed range, and achieves runout less than 0.005mm. Equipped with four upgraded high-precision steel bearings for up to 3× longer lifespan than standard models, it incorporates advanced dynamic balancing technology for minimal noise and vibration.
The water-cooled design provides excellent heat dissipation, significantly lower operating temperatures, and much quieter performance, making it ideal for long-duration, high-precision engraving and cutting.
The spindle is designed for VFD speed control, allowing operators to adjust spindle speed from 10,000 to 24,000 RPM according to cutter diameter, feed rate, and material requirements.
The ER11 collet system provides secure tool clamping for small-diameter engraving cutters, helping reduce runout and improve accuracy for fine carving, PCB milling, acrylic cutting, and detailed CNC work.
The spindle can be integrated with a compatible 400Hz VFD and CNC control system. Speed can be adjusted through VFD parameters, analog signal, or controller output depending on the machine configuration.
The 110V/220V configuration and 8A current rating support common CNC workshop power setups. Correct wiring, grounding, and VFD parameter settings are important for stable performance and spindle protection.
The 10,000–24,000 RPM speed range supports high-speed engraving, cutting, drilling, and finishing operations across wood, acrylic, plastics, PCB boards, and light non-ferrous metals.
The Φ65mm × 254mm water-cooled body and approximately 3KG weight provide compact installation while maintaining efficient heat dissipation and reduced operating noise during extended CNC machining.
