My question was trying to ascertain how much improvement you saw, relative
to Trapezoidal commutation. I was under the impression that the 7i93 already
did Trapezoidal commutation. Otherwise, what kind of motors does it drive?
When you rotate your motor shaft by hand, (open circuit) do you feel
cogging? If so, then it's not ironless, and would be more difficult to
control smoothly, especially at low speeds.
