Just to update the results of last nights test run of the cobbled up generator setup. While we had a devil of a time trying to make the diesel motor that we coupled up to the generator stay at 1800 rpm it stayed close enough for me to rapid my Z axis up and down at 295 IPM with the spindle turning 2k for about 5 minutes with no complaints from the Simodrive 611 despite the voltage varying wildly as motor powering the generator surged up and down.
So now I have two options as I see it and option B is preferred due to the noise of running a diesel generator. 1) buy a 3 phase generator to run the shop. B) figure out how to make my phase converter put out a proper 3 phase. If anyone has any ideas on option B I'm all ears. I have a small line reactor (rated at 3hp) that I can put on the phase converter output and see what that does. I see claims of true 3 phase power from rotary phase converters when searching for rotary phase converter and cnc so there must be a way cause these claims don't seem to be coming from small time shysters. Also Andy suggested me just making a DC power supply for the machine but the Simodrive 611 is a modular drive and the drive sections appear to have some communication with the infeed unit so that idea might not be possible without replacing the whole drive unit and I don't like that idea.
