The Zhong Hua Jiang ER11 62mm 1.8kW water-cooled spindle motor is a compact, high-speed motor for CNC engraving machines, precision routing systems and equipment integration. Its 62mm round housing, ER11 collet interface and published maximum speed of 60,000 RPM make it relevant to machine builders and professional buyers sourcing fine-detail machining components.
The published motor specifications identify 1.8kW power, 220V, 5A, 1000Hz, a stated operating range of 10,000–60,000 RPM, a Φ62 × 260mm body and 3.6kg weight. Buyers should confirm all electrical ratings using the motor nameplate and matching documentation before choosing an inverter or approving machine integration.
Water cooling requires a properly operating external pump, hoses and coolant circuit. An external high-frequency variable frequency drive (VFD) is also necessary. This page is for the spindle motor, not a documented VFD and water-pump kit.
For equipment manufacturers, wholesale distributors and professional CNC workshops, this motor can be evaluated for engraving, PCB work, acrylic cutting, wood carving and selected light nonferrous-metal processes, subject to the cutting tool, feed rate, workholding and machine rigidity.

Voltage, current and motor power must be verified as a complete electrical rating set. A 1000Hz spindle should not be connected directly to mains power or driven by a VFD whose output-frequency range is insufficient.
Request a Motor Drawing and 1000Hz VFD Recommendation
Application photographs illustrate common CNC machining categories, not universal cutting performance or proof of a particular feed rate. Work material, cutter geometry, cutter speed rating and the complete machine configuration determine suitability.
Suitable tools and machine settings can be evaluated for lettering, decorative routing and detail cutting in wood and MDF.
High spindle speed may be useful for suitably rated small cutters in acrylic and plastics; select feed and chip removal settings to limit heat buildup.
Light engraving and finishing of aluminum or brass should only be considered when the tooling, machine rigidity and coolant strategy support the process.
Discuss High-Speed CNC Spindle Applications
The published maximum speed is 60,000 RPM at 1000Hz. Select a VFD that can provide the specified high-frequency motor output and set its voltage, current, rated frequency, ramps and protective limits for the actual motor label.
ER11 tooling supports smaller tool shanks for detail engraving. Confirm the required collet bore size and maximum permitted collet, cutter and nut speed; a generic ER11 specification does not mean every available accessory is rated for 60,000 RPM.
CNC and PLC control systems can command a suitable inverter when their interfaces are compatible. The spindle itself is not a GRBL controller and should not be described as directly powered by a control board.
The manufacturer lists 220V and 5A in the supplied technical table. Motor engineers should confirm the current, phase and inverter output ratings for the exact version, particularly when calculating drive capacity and overcurrent settings.
Speed should be selected according to the verified motor limits, cutter rating, spindle-bearing condition, machining load and cooling performance. Higher speed does not automatically permit heavier cutting.
The listed spindle housing is 62mm in diameter and 260mm long, with a 3.6kg published weight. Confirm clamping area, coolant connections, connector clearance, mass and spindle travel before production of machine brackets.
Request Motor and VFD Integration Details
A standard 400Hz inverter cannot reach the published 1000Hz maximum rated frequency. Verify the selected VFD maximum output frequency, voltage, phase, continuous current and control interface against the supplied spindle nameplate.
Maintain suitable coolant circulation whenever the spindle is powered. The system requires compatible hose connections, a correctly selected pump and a reservoir or chiller arrangement appropriate to the machine environment.
At very high rotational speed, only appropriately rated tools, collets and nuts should be used. Confirm tool balance and installation before operation; overspeeding cutting tools or collets can cause serious damage or injury.
Use the motor-specific connector pinout and the VFD maker’s instructions. Verify protective earth, shielding, rotation direction and electrical interlocks with a qualified installer.
Confirm the Φ62mm housing diameter, 260mm published overall dimension, mounting clearance, coolant ports and Z-axis capacity before replacing a different spindle.

It is a compact CNC engraving spindle with a 62mm round housing, ER11 collet interface, 1.8kW published power, 220V rating, 1000Hz frequency and up to 60,000 RPM according to the manufacturer listing.
The published maximum speed is 60,000 RPM. Verify the actual motor nameplate and approved operating range, and use only cutters, collets and nuts rated for the selected speed.
The manufacturer lists 1000Hz rated frequency for its maximum speed. The inverter must support the necessary high-frequency output along with matching motor voltage and current.
A drive limited to 400Hz cannot reach the published 1000Hz rated operating point. Choose the inverter based on the motor nameplate and the required speed, not simply on its kW rating.
The published motor voltage is 220V. Verify the actual electrical rating on the motor nameplate and written order documents, then select a compatible inverter.
The published page lists both 1.8kW and 5A. Request motor-specific electrical documentation so the rated current, voltage and drive configuration can be validated together.
The page headline mentions an automatic tool changer, but the disclosed technical specification identifies an ER11 collet system and does not document an ATC actuator or tool-release interface. Confirm any ATC requirement directly before ordering.
Yes. The published toolholding type is ER11. Confirm the actual collet bore, nut configuration and maximum speed rating of the complete toolholding assembly.
The ER11 designation alone does not establish a speed rating. Use only toolholding components for which the supplier confirms a suitable maximum RPM and balancing requirement.
The published size is Φ62 × 260mm and the listed motor weight is 3.6kg. Request the dimensioned engineering drawing to check mounting length, clamping area and connection clearance.
Not directly without checking the mount. A 62mm motor does not have the same body diameter as a 65mm version. Use a correctly sized fixture and validate the machine load and clearance.
Yes. This is a water-cooled spindle and requires a suitable external coolant circulation system. The motor-only listing does not identify a pump as included.
Choose the pump, hoses, reservoir or chiller based on the delivered motor instructions and expected heat load. Maintain sufficient flow and keep the circuit free from leaks or blockages.
The source technical table identifies one 1.8kW round spindle motor. An inverter, pump, cooling hoses and other accessories should be quoted separately unless included in a confirmed package.
No. The motor is specified for high-frequency inverter operation. Use a correctly rated VFD and follow the manufacturer’s electrical wiring instructions.
The listing discusses fine engraving in wood, acrylic, plastics, PCB materials and selected light metal operations. Actual suitability depends on cutter rating, rigidity, cooling and machining conditions.
