Ok guys, here's the rub:
3hp 208 volt 3ph motor running on a 240 volt RPC.
It gets noisier and vibrates as it gets warmer.
I've tried to balance the converter as best I can, and get about 215-225 volts on the generated leg with the lathe running.
I'm not happy with the performance of this setup and need to change something here (probably the motor)
To make matters worse, I only have a 30 amp 240 volt circuit to my garage.
As I see it I can do one of the following:
1) replace the motor with a 240volt single phase, but I'm not sure if I have the power for that. ( motor currently on sale for $319 cdn)
2) replace the 208volt 3ph motor with a 240volt 3ph , and run it on the existing RPC ( motor sells for about $220cdn)
3) Buy a VFD and try the existing 208 volt motor on the VFD ( about $400)
4) buy a new 3hp 3ph motor and a VFD and enjoy all the benefits that I've heard about.
As always cheaper is better, but "fixed" is the best bargain.
any advise would be appreciated
