Still seems silly, but I guess it's the magnetic rotor or whatever.. would

nice to have a zero or 100 low rpm..

zero isn't all that useful, just turn the power off, but 5 or 10 RPM is
useful - I use that speed a lot to dry lacquer. But, with a direct drive
system,that means the motor needs to turn at that speed, and that poses some
challenges.

There are a couple of advantages to a belt drive - one is that the motor can
turn faster than the spindle, so you can get torque multiplication, and
another is that you get vibration isolation from the motor - not much of an
issue with a decent motor for wood turning

Yeah, that was sort of what he said, Bill...
The low speed of 100 rpm is fine, but you always want more than you get, right?
Also, the more I read about HOW the motor works in this thing, the more I'm
impressed.. No windings? Weird!
