What's a Centrifugal motor?

Quite. One might start by defining one.

That would depend on the weighting parameters used within the evaluation algorithm underneath the term <...best...>, which is a matter of personal judgement based on training, experience and particular circumstances, and therefore not a matter for an anonymous global engineering forum to ponder.

ASSuming you mean an AC motor on a centrifugal MACHINE...

the “best” way is to apply power to it in accordance to what you have available. Centrifugal machines are basically the EASIEST type of machine that can be attached to a motor, so any kind of starting method is fine. Figuring out which is “best” has to do with other facts not in evidence here.

I was thinking it was the kind of motor with a starting capacitor that is taken out of circuit once the RPM's had risen to the point that centripetal acceleration causes weights to overcome the spring pressure holding the contacts closed.

Therefore, the best way to start those motors is to apply power to them.

Oh duh! That interpretation (motor w/ centrifugal switch) never occurred to me.

The only reason I remembered that is the motor on my dad's 1950 Craftsman table saw 'clicks' once it passes about 50% unloaded RPM (guesstimate).

What does the motor manufacturer’s technical helpline say?
