Im looking at replacing my new lathes motor with a single phase AC or a DC motor for variable speed and have a couple questions.
When a motor is marked for 90volts, can it use 180 volts, and if so what will happen. Someone told me that the rpms will be doubled at 180 volts if the motor is rated for 90 volts and a set rpm at 90 volts.
If I go single phase ac, would I be able to use those variable speed control rheostats they sell for 20 bucks. I would be using a 3/4hp to 1hp motor and 110 volts. How do those work, and what do you lose with using them.
Thank you
