 It's too bad you can't get your hands on some test equipment to help you out! : )

 Please keep us up to date. That motor in the pic somehow resembles a computer hard drive motor.

 Yes, please keep us informed. I have a 3 phase motor controller project going on, and is hampered by my lack of knowledge of solid state. I'm a hollow state guy. I conferred with an EE friend of mine today, and put my 3 phase signal generator on an O scope, learned a lot. I have to drop back and punt on my project, but think I can make it work.

 It is the Papst motor for the Thorens TD124 special made as drop-in replacement for the E50 motor.

 I have a ROK B12h with the three phase Pabst motor. I have a keen interest in what your doing. Like Twysted I'm not a designer but a technition, give me a print and a parts list I can build it ( in fact from the parts I could probably get close enough). I'm a little lost when searching for the required components.

 Can you tell me about your three phase shift network? Are they available for purchase, or do you have to build the boards.
