CNC Router Machine Catalogue 2025.pdf
The Zhong Hua Jiang ER11 0.8kW round water-cooled spindle motor is intended for compact CNC routers, engraving machines, signage equipment and light-duty production systems. It combines an ER11 toolholding interface, a 65mm cylindrical body and variable-frequency operation for machine builders, professional workshops and spindle distributors.
The published product options are 110V or 220V, with a specified 400Hz operating frequency and 10,000–24,000 RPM speed range. Select the motor voltage to match the OUTPUT of a compatible VFD; the high-frequency spindle must not be connected directly to ordinary mains power.
Its water-cooled construction transfers heat to an external coolant circulation system instead of using a built-in air-cooling fan. This arrangement can be useful in enclosed CNC installations and workshops that need to manage spindle temperature and operating noise.
For equipment replacement or a new CNC router design, please provide the spindle mounting diameter, available Z-axis clearance, required ER11 collet size, supply voltage, VFD model and expected work materials. Our team can discuss motor selection and volume purchasing for your project.

This ER11 water-cooled spindle is designed for detailed routing and engraving. Typical applications include wood and MDF pattern cutting, acrylic sign work, plastics, PVC, PCB engraving and limited machining of suitable nonferrous metals. Tool choice, feed rates, machine rigidity and cooling determine the achievable result.
The application photographs show typical routing and engraving work. Capability depends on the cutter, workholding, spindle speed, feed rate and host machine; heavier metal-removal applications require a separate engineering assessment.
Discuss Your CNC Router Application
The 0.8kW spindle uses an ER11 collet interface and a compact 65mm round housing. It is intended to run with a correctly programmed 400Hz VFD, allowing spindle speed to be matched to the cutting tool and material within the stated operating range.
An external water-cooling loop is necessary for heat removal. The pump, hoses, reservoir or chiller should be selected for the spindle installation and kept clear of chips and contamination. The base product is a spindle motor, not a complete machine or a preassembled cooling system.
A compatible VFD provides motor start/stop and speed regulation. The CNC controller can interface with the VFD through supported control signals when the particular controller and VFD permit it; compatibility and wiring must be checked for each machine.
The ER11 system accepts correctly sized ER11 collets and the matching tool shanks. Collet size, nut style and tooling clearance should be checked before purchase, especially for replacement spindles and multi-machine procurement.
GRBL, PLC and other CNC control systems manage machine movement; the spindle requires a separately matched VFD to drive the high-frequency motor. Analog speed commands, relay outputs and other interfaces depend on the specific controller and VFD.
The product is offered in 110V and 220V variants. The source lists 6A; confirm the actual nameplate current for the selected voltage model, and size the VFD by its rated output voltage, current, power and frequency capabilities.
The published working range is 10,000–24,000 RPM at a stated 400Hz rated frequency. Any minimum speed, acceleration or braking setting must follow the motor nameplate and the actual application; avoid assuming that lower speed is suitable for prolonged high-load cutting.
Unlike an air-cooled spindle, this motor requires continuous coolant circulation through its water jacket while running. Plan a suitable pump or chiller, hose routing, leak protection, coolant management and routine checks of water flow and temperature.

Spindle balancing and secure tool clamping help limit vibration at operating speed. Final machining quality also depends on the collet, tool length, cutter condition, installation alignment and machine rigidity.
The published product listing describes a four-bearing construction and mentions steel bearings. For a purchase specification, request confirmation of the bearing material and arrangement for the exact 0.8kW version rather than applying a general service-life estimate.
