| Mar 1, 2017 at 13:18 | comment | added | AngeloQ | Bruce do you have any thoughts on how that calibration would be done? Would it be something like adjusting the zero reference to achieve maximum torque? | |

| Feb 23, 2017 at 20:41 | comment | added | AngeloQ | Thanks @Bruce, good point on the low speed back-EMF. So the encoder would be used for position and commutation? Can I assume that the position would be referenced to the windings somehow physically? I noticed in the datasheet that the encoder can be zeroed. I'm just concerned about the encoder position being arbitrary relative to the windings. | |
