Re: IT'S ALIVE!!!

Tim,

To me that is a distiction without a difference. What are commonly
reffered to as "brushless DC servomotors" are in fact 3-phase AC
motors requiring external commutation (6-step Hall sensors or encoder
feedback). When running, the motor drive signals are 3 AC waveforms
offset at 120 degree intervals.
