Cheap Chinese Motor

[stevec]

dallen, I'm quite aware of the variable speed feature and suggest that speed control down toward 0 rpm would be next to useless, you need the torque increase of the mechanical advantage obtained by pulley or gear changes.
I was inquiring about the smoothness(is that a word?) with 3 phase motor equipped machines.
I have read that finish is greatly improved, at least on a lathe that is.
