Many dinosaurs still extoll the virtues of the rotary phase converter,
but having now set up two machines with VFDs, I'm even more firmly
in the other camp. They just can't be beat for size, weight, noise level,
efficiency, and of course, the benefits of variable speed and braking.
I love the quick stop I get on both the mill and especially the lathe,
where it is far quicker than letting the machine coast to a stop.

(I mean no offense to above mentioned dinosaurs, and I understand that
some people are running a shop on an EXTREMELY thin budget, and
the price of even a used VFD is too much.)
