Ahh, I found your item. it looks like yours has a universal motor. Mine
has
an AC induction motor. It will take 900 Hz power to get to 54000 RPM.
So, I can only go up to 24000 RPM with my VFD, it only goes up to 400 Hz.
But, I suspect the collets and air filter are the same. there is another
Precise spindle of a different design that went unsold (starting at $1000).
There are collets in the picture. Search the closed auctions for precise
spindle, and 4 items should pop up, including that one.
