CNC Router Machine Catalogue 2025.pdf
This 5kW CNC spindle motor is an option for machine manufacturers, equipment service companies and distributors sourcing a square-body spindle for higher-power woodworking and engraving machines. The ER32 collet interface accommodates compatible tooling with the appropriate ER32 collet size and nut.
Typical machining materials include wood, plywood, MDF, acrylic, PVC and other machinable plastics. Selected engraving and light milling tasks on aluminum or brass may also be possible, depending on spindle speed, tooling, machine rigidity and process parameters. Material compatibility does not imply suitability for every cutting operation.
The integrated air-cooling approach avoids the separate pump, reservoir and coolant lines used in many water-cooled spindle systems. The motor is offered as a spindle-only product; a correctly rated VFD and mounting hardware should be selected separately unless explicitly included in the confirmed quotation.

Request Technical Drawings and VFD Matching
Application suitability depends on the cutting tool, feed rate, depth of cut, fixture stability, spindle-speed setting and machine stiffness. The following images show representative CNC machining materials and applications.
For woodworking CNC equipment, the ER32 tool-holding interface offers flexibility for compatible router cutters. Verify cutter shank diameter, collet fit and appropriate cutting parameters.
For plastics processing, select suitable cutters and chip-clearance settings to help manage heat generation and material finish.
Light machining of soft metals requires careful selection of spindle speed, cutting tool, chip evacuation and CNC machine rigidity. Confirm the machining duty with technical support for production applications.
The ER32 interface supports compatible precision collets for securing cutting tools. Actual tool-shank capacity depends on the selected collet size, not the interface name alone.
The published 5kW output supports spindle selection for higher-power CNC routing applications, subject to motor loading, tool geometry and machine operating conditions.
The square motor housing and mounting arrangement are suitable for equipment designs that accommodate its physical dimensions and installation points. Confirm fit before retrofitting a different spindle.
Use a VFD that matches the motor nameplate, rated output, voltage and required frequency range. Controller start/stop and speed-command compatibility should be checked separately.
The listed voltage choices are alternatives rather than a single universal input specification. Specify the exact power-supply arrangement when requesting pricing.
The spindle dissipates heat through an air-cooled design. Maintain ventilation and keep the fan/cooling passages clear in an enclosed CNC machine.
The product is marketed as a four-bearing configuration. Because published materials describe different bearing materials, specify the required ceramic or steel bearing design when purchasing.
Request ER32 5kW Motor Configuration
Illustrations in the wider spindle product range can depict other frequency or speed versions. The published specification for this ER32 5kW model is 300Hz and 10,000–18,000 RPM; do not use a different model’s 24,000 RPM graphic as its operating limit.
Spindle balancing and bearing selection influence vibration, noise and finishing performance. Request a bearing specification or inspection record if these characteristics are required for acceptance.
The source product materials contain different runout claims. Comparison visuals are provided for reference; the acceptance runout must be stated with a measuring location, tool/collet setup and test conditions in the purchase specification.

Check the spindle mounting holes, wiring pinout, earth connection and VFD parameter settings before commissioning. Installation and electrical work should be performed by qualified personnel.
The source listing describes the standard spindle-only shipment as one square 5kW air-cooled spindle motor, a pre-soldered aviation wire and two wrenches. A VFD is required for use but is not included in the displayed standard package list.
For bulk orders or equipment-building projects, send the intended voltage, VFD model, mounting dimensions, required cable length and packing requirements with your inquiry. Additional accessories or bundled configurations are subject to quotation.

The published standard package lists the spindle motor, a pre-soldered aviation wire and two wrenches. A VFD is required but is not included in that package list unless separately quoted.
The manufacturer lists 220V and 380V versions. Confirm the motor nameplate and electrical supply before ordering; these are configuration alternatives.
The listed model has a 10,000–18,000 RPM operating range with a 300Hz reference frequency. Final permissible speeds should follow the supplied motor nameplate and VFD settings.
Select a suitably rated inverter according to the spindle power, nameplate voltage, output current and required frequency. Confirm controller commands, grounding and installation requirements before operation.
The product description specifies a 300Hz operating frequency. The inverter should support the actual motor requirements; correct frequency programming alone does not establish complete compatibility.
The ER32 collet system accepts compatible ER32 collets. The tool-shank size is determined by the particular collet and tool, so confirm your cutter diameter when specifying tooling.
The published standard package does not separately list a full set of ER32 collets. Ask for the included collet size and any additional collets needed for your machine.
The published overall dimensions are 372 × 95 × 106mm. Request the mounting drawing to verify hole positions, body clearances, connector orientation and available Z-axis space.
The product listing gives a motor weight of 10.5kg. Confirm the shipping weight and packaging dimensions separately for logistics planning.
The product title refers to a four-ceramic-bearing version, while some description content refers to steel bearings. Confirm the bearing configuration on the specific model and quotation.
Published source material contains different runout figures. For precision applications, request a confirmed measurement method and inspection or acceptance tolerance for the unit you are purchasing.
Selected soft-metal engraving or light milling may be feasible with suitable tooling and a rigid machine. Validate cutter size, feed, speed, chip removal and operating duty before production use.
Wood and MDF are among the published applications. Final tool selection and cutting parameters depend on material, cutter geometry, depth of cut and router capacity.
The spindle does not require an external water pump, coolant tank or cooling lines. Adequate ventilation remains necessary, especially in enclosed equipment.
Not without confirming mounting compatibility. Compare body shape, mounting plate, bolt centers, spindle height, weight, wiring and VFD specifications before replacing the existing spindle.
Control through a compatible VFD may be possible. Confirm the specific VFD interface, speed signal and start/stop wiring against your CNC controller design.
The original list specifies one 5kW square air-cooled spindle motor, one pre-soldered aviation wire and two wrenches. Any other accessories should be checked in the final quotation.
Both voltage options appear on the product page. Buyers should state the required version, order quantity and destination market so the configuration can be reviewed.
