Question #: 14632

Question: What is the minimum RPM for the 2.2 kW spindle? Info on spindle page says 0-24,000. Elsewhere in this knowledge base it says 6000. My edge finder has a1500 RPM limit.

Current Solution

The lowest Hz for a 2 pole 2.2kW spindle is 250 Hz. That works out to 15,000 RPM. If you need lower RPM, a separate spindle will be required. This is typical for industrial CNC machines where spindles are changed out to mill on different materials.

Additional Information:
Thank you for the reply.

Does that mean the 2.2 kW spindle sold by BYCNC is a 2-pole, not a 4-pole? There don't seem to be specs on the website for the 2.2 kW spindle.

I currently have the 1.5 kW spindle from BYCNC and can run from 0-24000. 1500 is no problem. I never mill at that low of a speed, just use the edge finder to set the workpiece coordinates.
