Technical FAQ & Operational Guide
What is the primary advantage of the round design?
The round body design is extremely compact and standard across many CNC machine mounts. It is particularly popular for multi-spindle setups like bangle-making machines or small footprint PCB routers where space is a premium.
Can this motor reach 24,000 RPM safely?
Yes, it is rated for a top speed of 24,000 RPM at 400 Hz. The high-quality P4 bearings and integrated fan are specifically balanced to maintain stability at these high rotational velocities.
Does this spindle require a special inverter?
You must use a Variable Frequency Drive (VFD) that supports a 400 Hz output frequency to run this spindle at its full 24,000 RPM capability.
