Hi Gary, all,

Although I agree that you won't have a full range of RPM conrol of a
brushless induction motor with a dimmer, I disagree that it won't work
at all. I use a dimmer for a limited control of my asynch RSG, and I 
can probably vary the the RPMs by at least 50%. No, it's not as good 
control as a variac, but it still works good enough for finding a sweet 
spot in the phase. And though the motor does tend to get quite warm 
after extended run time, I never run my 10 kVA system for more than a 
few minutes at a time.
