How much do you recommend one should mill off of a typical motor? This
effectively makes this a salient pole motor...sort of. For example, I am
using a 1/2hp, 230V,4-pole,1750 RPM motor which I start at about 280V so
it can "Lock-in" and then I reduce the voltage through time delay to
240V...If I leave the voltage high, the current input exceeds the
nameplate rating and the motor runs excessively hot. What luck has
anyone out there had? Suggestions for milling depth would be helpful,
and appreciated, since I'm getting ready to mill down another armature

Yes, the motor modification will work. Mill two flats.
