    9mH inductance :(

    A very crude mental calc shows that at 100rpm on 68v you'll be struggling to get little more than 2Nm torque and at 200rpm it's going to be nearer 1Nm, so you've got less than 1Nm available to accelerate the load through that range.

    The AC drivers still provide dc to the motor so 100vAC is crudely 140v DC so at 68v the performance is going to be roughly 50-60% of the 100v AC curves.
