Re: [CAD_CAM_EDM_DRO] crank as hell

Hello folks,
a off topic question.
For a actually working centrifuge (High frequency induction for metal
casting)
I shall put a new motor on that starts up much faster.
The 7 kg cross beam of 73 cm length needs with the original 250 watt
(1/3 hp)
normal single phase motor two turns to come on speed.
Result: The castings come out defective.
First I thought about to put a 1 or 2 hp three fase motor on it.
Are there other motor types that still have a better cranking at the
start up???

Sorry, but 95 percent of my daily bread experience is based on three
fase motors.
The rest is a closed book for me.
Thank you for any response.
