Some time ago I saw an article or a posting on a way to modify a three phase motor by reconnecting the leads somehow that makes the motor easier to start and run on single phase power. I THINK I saw it here. This modification does NOT make the motor a single phase motor. I think it required a 12 lead motor to work, and the connection was not a simple delta or wye. The concept was named after the inventor, whose name I am also drawing a blank on, or so I recall (e.g., the "Johnson Motor").
I did searches here with any and all terms I could think up, all to no avail. At the time I saw the article or posting, I thought, "gee, that's neat", and bookmarked it or saved a PDF or something, for future use. Unfortunately, that computer has gone to computer heaven and I no longer have the information.
Can anyone help me out here? I am working on a machine that has an extremely built-in 440V only three phase 1HP motor on it. I pulled the field with the idea of reconnecting for 220V and was pleasantly surprised to find the splices very conveniently located. I can probably bring out all 12 leads if it will help but I won't unless I can find the information on the modification mentioned above.
Thanks,
Steve
