Other Parts Discussed in Thread: MCF8329A, MOTORSTUDIO, , MCT8329A
I am trying to get a motor to run a bit faster than the top speed I'm currently achieving with the MCF8329A (at a fixed bus voltage). Preferably close to the speed I can get with a trapezoidal controller. I have tried experimenting with the flux weakening controls in MotorStudio, but they seem to have no effect at all. Can anyone provide some guidance on this? I also notice a control in MotorStudio named "OVERMODULATION_ENABLE" which is grayed out. This sounds as if it might be of interest, but I find no documentation about it anywhere. What is this for?
Ideally the controller would operate in normal FOC mode up to the maximum speed that can be achieved that way, and then switch into a more trapezoidal waveform for speeds above that. If an automatic switchover is not available, explicitly switching would work for my application.
