I have a couple of questions; I'm trying to catch up here.
Is the PI loop for overall motor control or specifically for induction motor control, IE controlling the slip?
Also, thingstodo: Does your stepson need a Siemens motor? I've got one. It's practically brand new - first it sat in Brammo's shop, where they were going to do a 4 motor AWD racecar. Then I got it and it sat in my shop. (I've decided to go with the Toyota MGR).
