CNC Spindle Motor 2.2 kW, 18000 RPM, 220V/380V Air Cooled Square

The 2.2 kW Square Air-Cooled Spindle Motor is a high-performance solution engineered for precision and reliability across multiple industries. Operating at 18,000 RPM with a frequency of 300 Hz, this motor is uniquely designed with dual-voltage compatibility (220V/380V), allowing for flexible integration into various power environments. Its square body design ensures a rigid and stable mount, which is critical for maintaining accuracy in high-speed applications such as PCB routing, brush manufacturing, and intricate bangle designing. Equipped with a precision P4 bearing set (7005 & 7002), the motor provides smooth rotational delivery and minimal runout, making it equally effective for automotive deburring and general CNC wood routing.

Technical FAQ & Operational Guide

How does the dual-voltage feature work on this motor?

The motor can be configured to run on either 220V or 380V depending on your VFD settings and wiring configuration.

What size tools can I use with the ER20 collet?

The ER20 collet system allows you to clamp tool shanks ranging from 1mm up to 13mm in diameter.

How is the rotational balancing calibrated on this spindle motor?

Every spindle motor is dynamically balanced in accordance with the ISO 1940 balancing standard to guarantee vibration-free running and maximum stability at high RPMs.

What are the runout tolerances of the shaft and collet interface?

The internal shaft taper maintains a runout accuracy tolerance of under 0.003mm (3 microns), maintaining precise tool concentricity and preventing premature cutter wear.

What cooling precautions are built-in to prevent heat exhaustion?

Built-in temperature dissipation channels support continuous water/liquid cooling circulation or forced fan airflow, preventing thermal expansion of components.

Is this spindle motor compatible with standard VFD inverters and collets?

Yes, the spindle supports direct electrical integration with standard variable frequency drives (VFD) and accepts industrial ER collets (ER11, ER20, ER25, or ER32) to match standard toolholder dimensions.
