BPT had a single phase motor for its J head (step pulley) but it was very costly. Since this head was phased out a few years ago, I do not know if the single phase motor is even available. I do not remember a single phase motor for the 2J head being available but I will check. If anyone has the maintenance manual, they list replacement parts in a section in the back (including motors). I believe it is possible to find a single phase replacement motor for the old J head. Fife-Pearce has a lot of BPT motors and parts. They may also have one.
In simple terms, a rotary phase converter is a static phase converter running a 3 phase motor hooked in parallel to your 3 phase BPT motor. I have seen some very reasonably priced on Ebay. A static phse converter is a box that artificially creates a 3rd leg for starting a motor, then it drops out. Needless to say a 3 phase motor does not have the same HP running on single phase as it does running on three.
