Busy with some extremely interesting stuff.
I've started programming on a different chip, one of the 33EV types. Goal is to have sensorless start with full torque at standstill. Relative (sensorless) position at standstill is quite easy, but to get absolute phase information requires a bit more doing. The picture above shows the different versions of analog signal processing that I am considering for processing the current sensor signals. The left one has 4 opamps, the right one 8 at the moment but should be 10... but have already scrapped that one in my mind and am drawing up schematic for version 3....
The new processor plugges onto the powerPCB. The analog bits plug into the bottom right header of the experimental processor board.
