I have a 3hp 3phase 2 speed motor on a bridgport style milling machine. It says it is 2/4 pole 3400/1700 rpm. My question is should i wire it up to the high speed and max the frequency at 60hz or wire it up 4pole and try to run at 120hz to get the 3400 rpm. Will it have better low speed power with the 4 pole and what will it do to the highspeed power? Any help appreciated. I have attached a pic of the name plate on the motor if it helps any.
