Monarch 10EE Restoration 4: Drive Electronics Removal

In this video I perform a quick demonstration of the MG and then dismantling of the drive electronics. Overall the wiring is still very well labeled. I haven't decided yet if I will replace the oil saturated wires - or just recrimp ring terminals. Although the MG appears to work well I am conflicted. I appreciate its ingenuity and am a bit sentimental. It's capable of high-torque at a wide RPM range with not a single semiconductor. However, eventually I must address my lack of three phase power. At the moment I'm borrowing the 3HP static phase converter from the surface grinder and only running for very short durations. Moving forward I see four options: A) Power the MG with a larger static phase converter B) Power the MG with a rotary phase converter C) Power the MG with a VFD D) Remove MG and power a new motor from VFD I want to avoid the HP penalty of option A and my shop is too small for option B so I am leaning toward option C or D. I fear option C may eventually result in scouring the web for increasingly sparse replacement parts and option D will simplify the drive, is easy to troubleshoot, and quiet. I remain conflicted but for now will baseline option C. For those who have struggled with this same decision what did you end up choosing and why?
