Is this 5.5 kW motor suitable for marble and granite?

Yes, the 5.5 kW power rating and 2.91 N.m torque provide the high cutting force required for processing dense materials like marble and stone. The water-cooling system is essential for maintaining accuracy during the long cycles typical in stone carving.

What is the benefit of the ER25 collet over ER20?

The ER25 collet system is more robust and supports larger tool shanks—up to 16mm. This allows for the use of larger material removal bits and provides higher clamping force, which is critical for the 5.5 kW power rating and the high-torque tasks this motor performs.

Does this motor require a specific VFD?

Yes, this motor must be paired with a Variable Frequency Drive (VFD) rated for at least 5.5 kW and 380V output. It should be configured to run at 400 Hz to achieve the full 24,000 RPM speed safely.
