Why is an 'Independent Fan' better than a shaft-driven fan?

A shaft-driven fan's cooling capacity drops as RPM decreases. An independent fan runs at a constant speed, ensuring the motor stays cool even when running at lower RPMs for heavy torque tasks.

What is the maximum tool shank diameter this spindle can hold?

Using the ER32 collet system, this spindle can accommodate tool shanks ranging from 2mm up to 20mm.

Can this motor run on a 220V single-phase supply?

No, this motor is specifically rated for 380V 3-phase supply. Attempting to run it on 220V will result in power loss and potential damage to the windings.
