Browse the catalogue for the broader spindle motor, CNC router and accessory range. For the current 1.5kW ER11 motor configuration, request a model-specific technical sheet when comparing options.
The 65mm round body is intended for machines equipped with a compatible spindle holder. Compared with a lower-rated spindle, the 1.5kW class is an option for applications requiring additional motor power, provided the CNC frame, spindle mount, electrical system and selected cutting tool are appropriate.
Its air-cooled housing eliminates the separate pump, hoses and coolant circulation needed for a water-cooled spindle. Adequate ventilation, cooling airflow, dust management and proper VFD commissioning remain important for reliable operation.
Request Motor-Only or Kit Configuration Options
A suitable 400Hz-capable VFD is needed to operate this high-frequency spindle. The motor should not be connected directly to standard mains power. Confirm the motor nameplate, rated voltage, current, speed range, terminal connections and grounding before wiring.

Machine controller integration, including GRBL-based systems, depends on the selected VFD and available control interfaces. Do not assume that a spindle motor itself communicates directly with CNC software; a suitable VFD and correctly wired control signals are required.
Confirm VFD Compatibility Before Ordering
The spindle can be evaluated for wood engraving, MDF routing, acrylic and plastic cutting, PCB engraving and light-duty aluminum or brass work. Tool geometry, spindle mounting rigidity, material grade, feed rate, depth of cut and chip evacuation determine whether a specific application is suitable.
Common applications include detailed engraving, contour cutting, signmaking, decorative panels and wood component processing. Use cutting tools and feeds matched to the material, dust extraction and machine rigidity.
The ER11 tool interface supports suitable small-diameter routing and engraving cutters used in acrylic, PVC and other plastics. Match spindle speed and feed rate to the material to limit melting, burrs and excessive heat.
Light aluminum or brass engraving and shallow milling may be feasible with a rigid machine, correct tool, suitable workholding and conservative cutting parameters. This compact ER11 spindle should not be presented as a replacement for a dedicated heavy-metal machining spindle.
Discuss Your Material and CNC Machine
The 65mm housing suits appropriately sized circular spindle mounts. Confirm the mounting diameter, overall length, tool clearance and machine Z-axis capacity before replacing an existing motor.
The ER11 interface is designed to accept matching ER11 collets and compatible tool shank sizes. Confirm the exact collet supplied with the motor; the full collet assortment included in separate kit listings should not be assumed to come with this motor-only product.
The listed speed range is 10,000–24,000 RPM, with a 400Hz rated operating frequency. Speed control is provided by an appropriately selected and configured VFD, rather than by connecting the motor directly to an ordinary power supply.
Integrated air cooling can simplify installation where routing space is limited. Keep the ventilation path open and manage dust exposure, ambient temperature and sustained machining loads according to the manufacturer’s operating instructions.
The supplier describes a four-bearing design and dynamic balancing measures intended to support stable high-speed rotation. For projects requiring a particular noise level, runout tolerance or service-life target, request inspection criteria and current production data for the chosen model.
Request Specifications for OEM or Distributor Orders

Dynamic balance is an important aspect of high-speed spindle design. Mounting alignment, VFD settings, cutter balance and machine condition also affect noise and vibration during operation.
The published description refers to four upgraded steel bearings and a copper-wound rotor. The operating life depends on loading, cooling, dust ingress, maintenance and correct electrical configuration; request current bearing specifications where they are material to procurement.

Select a spindle using the CNC frame stiffness, required mounting diameter, cutter shank, material, duty cycle and VFD compatibility—not power rating alone. The 65mm ER11 round option is particularly relevant where the machine is designed around a cylindrical spindle mount and small-diameter cutters.
ER11 and ER16 are different collet systems. ER11 is commonly selected for smaller tool shanks, while ER16 offers a larger collet format. Changing between them can require a different spindle and mounting arrangement; verify tool diameter requirements before ordering.
A 1.5kW model may offer more rated power than an otherwise comparable 0.8kW spindle, but performance at the cutting edge depends on spindle design, speed, tool diameter and the CNC machine. Motor size and weight should be checked for compatibility with the machine’s Z-axis.
Air-cooled designs do not need water circulation equipment, reducing auxiliary installation components. Water-cooled designs use a separate cooling circuit. The suitable option depends on installation conditions, noise requirements, dust exposure and intended operating cycle.

This product is the ER11 65mm 1.5kW round air-cooled spindle motor. Earlier descriptive material contains references to a 0.8kW motor; the main product listing identifies this model as 1.5kW. Confirm the nameplate on the ordered variant.
The motor-only packing list does not identify a VFD as included. A compatible 400Hz-capable VFD must be selected separately, or a dedicated VFD kit can be quoted.
The published product summary identifies a 65mm round body and a size of Ø65 × 268mm. Request a dimension drawing to confirm mounting surfaces and the required Z-axis clearance.
The advertised operating speed range is 10,000–24,000 RPM. Safe operating limits and programmed VFD frequency should follow the motor nameplate and product instructions.
The supplier lists 110V and 220V options. They should be treated as specific motor/VFD configurations, not proof that an arbitrary single motor or inverter accepts both inputs without checking its rating.
Check rated motor power, current, output voltage, rated frequency, overload capability and the VFD interface used by your CNC controller. The main product summary lists 1.5kW, 8A and 400Hz.
No. This high-frequency spindle requires a suitable VFD to supply the motor with the required variable-frequency output. Installation should be performed by a qualified technician following applicable electrical safety requirements.
Use ER11 collets sized for the tool shank and compatible with the spindle assembly. The exact supplied collet size or assortment is not fully established by the motor-only packing list; confirm inclusion before purchase.
Potentially, through a compatible VFD interface and appropriate signal wiring. GRBL does not directly control a high-frequency spindle motor, and compatibility depends on the controller hardware and VFD parameter settings.
Wood, MDF and decorative sign engraving are among the typical applications. Select the cutting tools, spindle speed, dust extraction and machining parameters to suit the material and CNC machine.
Acrylic, PVC and similar plastics may be processed using appropriate tools, feed rates and chip evacuation. Poor cutting settings can cause melting, rough edges or tool overheating.
Light-duty work in some soft metals may be possible with a rigid machine and suitable cutting conditions. It is not represented as a general heavy-metal milling spindle; confirm the intended depth of cut and duty requirements.
The motor does not require an external pump, water lines or coolant reservoir. Adequate air circulation and cleaning are still necessary, particularly when routing dusty materials.
The main product listing states 3.2kg; other descriptions on the same page give lower figures. Confirm the actual model weight with the supplier, especially if the load capacity of the Z-axis is critical.
The original page displays a comparative image describing runout below 0.005mm. Because the test method and acceptance conditions are not defined, buyers should request an inspection report and agree the runout measurement criteria.
The original packing section lists one spindle motor and one pre-soldered aviation cable. Confirm whether collets, wrenches, clamps, connectors and any other items are included in your final quotation.
Yes, the company invites distributor and OEM enquiries. Send the required voltage, motor quantity, mounting information, tool system and destination to request commercial terms.
