The 500W air-cooled spindle kit can be considered for engraving, drilling and light cutting on wood, MDF, acrylic, plastics, PVC and PCB substrates, subject to the bit, router frame and cutting parameters. Soft metals may require shallow passes and careful setup; this compact kit is not presented as a heavy-duty metal-removal spindle.
Useful applications include engraved nameplates, wooden signs, decorative lettering, small craft components and desktop prototyping.
For plastic displays, templates and acrylic artwork, select appropriate tooling and chip removal. Cutting depth, melting risk and edge finish depend on tool geometry, feed rate and material grade.
Light marking or carefully controlled machining of soft aluminum and brass may be possible on suitable CNC equipment. Confirm that the machine frame, holding fixture, tool and controller can support the intended operation.
Published motor data for the 500W spindle is shown below. The 500W motor rating and the separately listed DC 100V / 4A operating values should be checked against the current motor datasheet before electrical integration; these figures do not establish one simultaneous rated operating point.
| Operating Voltage | 100VDC | Speed | Up to 12,000 RPM at idle |
| Power | 500W | Torque | 5000g/cm |
| Current | 4A | Insulation Resistance | >2 megohms |
| Motor Length | 200 mm | Dielectric Strength | 400V |
| High Precision Spindle Runout: 0.01-0.03 | |||
The supplier lists the torque as 5000g/cm and spindle runout as 0.01–0.03 without an explicit unit in this table. Request a current dimensional drawing and the manufacturer’s test method for critical precision or torque applications.
The included speed converter accepts AC mains input and supplies adjustable DC voltage to the motor. It is described as a DC speed controller in this page, rather than a variable-frequency inverter for three-phase AC motors.

| Output Current Peak | 6A | Air Temperature Around | -10~40°C |
| Adaptive Motor Power | 100W-500W | RH(Relative Air Humidity) | Under 85%, Ventilated |
| Output Voltage | DC 0-100V | ||
| Please install in the place that is ventilated, no dramatic impact, no vibration, no explosion hazard medium, no conductive metal particle. | |||

The package lists three ER11 collet sizes and ten engraving bits. Check the selected tool-shank diameter and collet specification before use; choose tooling and feed rates suitable for the machine rigidity and workpiece material.
Request the 500W Spindle Motor Datasheet
The published package includes a 52 mm spindle mounting bracket. Confirm the motor housing diameter, mounting bolt arrangement, machine Z-axis clearance and gantry load capacity; the bracket size alone does not guarantee that the kit fits every 3018, 3020 or other CNC router.
The motor is listed at 100VDC, and the controller is listed for AC 110V/220V, 50/60Hz input and DC 0–100V output. Specify your local AC mains voltage, controller version, emergency-stop requirements and electrical protection details with your enquiry.
The source package identifies a speed governor with Mach3 support. Confirm the actual speed-control input, compatible control signals, wiring and selected controller version before integrating it with Mach3 or any other CNC controller.
Request a 500W Spindle Kit Compatibility Check

The published kit list includes one 500W air-cooled spindle motor, one 52 mm mounting bracket, three ER11 collets (1/4 in, 1/8 in and 1/16 in), ten drill bits, one brush, one power wire, two wrenches, one fast wire connector and one AC 110V/220V speed governor with stated Mach3 support.
The supplier lists a spindle speed of up to 12,000 RPM at idle. Actual speed under load and cutting performance depend on the controller setting, tooling and material.
The motor is specified as a DC spindle with a published operating-voltage listing of 100VDC. The supplied converter takes AC 110V/220V mains input and provides a listed DC 0–100V output. Check the exact controller variant before connection.
The published kit includes a speed power converter for a DC spindle motor. It should not be assumed to be a conventional three-phase AC spindle VFD; the documented converter output is DC 0–100V.
The listed mounting bracket is 52 mm. Confirm the actual spindle housing diameter, Z-axis attachment and available clearance on your CNC router before ordering.
The published kit includes three ER11 collets in 1/4 in, 1/8 in and 1/16 in sizes. Match the collet to the cutting tool shank and inspect the tool before use.
The kit is intended for desktop CNC engraving and light cutting. Common applications include wood, MDF, acrylic, plastics and PCB substrates. Results depend on the machine rigidity, tool, cutting parameters and workpiece material.
Light marking or shallow cutting on suitable soft metals may be possible with the appropriate router, cutters and feeds. This compact kit should not be assumed suitable for heavy metal milling.
The published packing list identifies the speed governor as having Mach3 support. Confirm its control input type, wiring, compatible firmware and the exact controller model before integration.
The 52 mm mounting bracket may be relevant to some desktop CNC builds, but compatibility must be verified by checking mounting geometry, spindle weight, controller signals, mains input and Z-axis clearances.
