After a few suggestions and the fact that the controller part fits better in the technical forum I will be placing future controller related information in this thread and leaving the old thread for the mechanical / bike part
The old thread can be found here http://endless-sphere.com/forums/viewtopic.php?f=28&t=20766.
That thread will remain for the bike related parts only. Unfortunately that thread to too intertwined to make one of the other so for early controller development you will have to refer to it. I will past some of the important parts into this thread.
---------------------
Summary:
This controller consist of two boards.
1) a control board that will support hall sensor, rotary encoder, or sensorless operation depending on the software settings.
Full sinewave vector control is planned although the very first software will be hall effect trapasoidal to keep things simple while I
debug the power board.
This board features a 120MHz processof and 12Bit simulatanious sampling ADC
suports twin CT's in motor phases.
2) An example power board sporting 12 x TO-247 devices .
This design is not the low cost option but it should result in a very robust system.
I plan to sell built up controller or boards once I have everything debugged.
I could even consider bare PCB's for those keen enough.
For those with the skills to build an output stage I will sell control boards with software.
I will provide some documentation when I get time.
I just a bit busy getting some software ready for when the bare power boards arrive in early december at the moment.
