Few years ago when you posted this! But I'm just wondering if you have any thoughts on the motor now, since I'm thinking of buying one but can find almost no reviews online about them, no reviews at all even on aliexpress. Especially curious if they are suitable for more precision work, since they only have 2 bearings. I only need to run at around 24k rpm, just need a small er8 motor.

Have you run this at 60k for very long? I have what looks to be the same spindle (mine is a 300w from keling/automationtechnology) I ran a long cut with it at or near 1kHz, and burned out the bearings (smoke was coming out.) Got a replacement, but notice the front end gets quite warm and power jumps up (unloaded, ) when going much over 40k.

I am guessing you are going far far too slow for 60krpm
