What are the advantages of a 6-pole motor design for milling?

A 6-pole design significantly increases torque (6.5 Nm) compared to 2 or 4-pole motors. This provides more power at lower speeds, allowing the spindle to maintain RPM under the heavy resistance encountered during metal milling and large-diameter drilling.

What type of inverter is required for this 12kW spindle?

You will need a high-frequency Variable Frequency Drive (VFD) rated for at least 12kW (or 15HP) that supports a 900 Hz output frequency and 380V 3-phase input.

Is the cooling system adequate for 24/7 industrial use?

Yes, the high-flow water cooling system is specifically designed for continuous industrial duty cycles, maintaining internal temperatures and protecting the P4 grade bearings during prolonged operation.
