I haven't seen any parallel AC controls running a single motor. I have seen one AC control running multiple motors however. This was common in some applications that run several motors at the same V/Hz ratio. Our sensorless BLDC control at work can even run multiple 3 phase 12 slot BLDC motors in parallel (we have 5 motors per control on a test fixture). The problem with parallel controls is that the frequency and voltage magnitude would have to match up perfectly or the controls would be working against each other. Rod
I haven't done it, I heave heard that it can be done. Similarly, paralleled power semiconductors in a controller sent to individual motor leads has been done, I am told. Games can be played this way to use cheaper power silicon and/or enhance efficiency at less than full power.
