These motors came with tachsyns, a relative of the resolver, but not designed for positioning resolution. So, I pulled those off, but have to turn the motor shafts down a little to fit a 6-channel encoder. I just haven't gotten around to doing it, yet. Then, the commutation tracks of the encoder would be fed into digital I/O so the hal bldc component would have an initial position to know the rotor alignment. Then, bldc would send signals through two DAC channels to control the 7225 amps. Then bldc would use the encoder count after homing to provide sinusoidal commutation for the motor.
Sorry I don't have working hal files for this, yet.
