The reason I added the *disclaimer* ( if the drive is not doing anything tricky) at the bottom of my calculation is for this reason, just in case we started to enter some advanced motor control. If the motor is wound in the correct fashion it is a vaild approach to move the field weakening point, see the attached document.
