ABSTRACT:
A multiphased permanent magnet generator (PMG) driven by a rotating shaft, generates a multiphase output which is integrated and applied as the input to a high resolution phase locked loop having a binary counter with an output phase locked to the PMG multiphase output and representing shaft position. As applied to a high performance synchronous drive in which the PMG is driven by the synchronous machine, the digital shaft position signal is used to generate a multiphase current reference signal which is tracked by stator currents generated for the synchronous machine by a power current source. The multiphase current reference signal can be generated by a selected set of multiphase digital sine waveforms stored in a ROM which is part of the phase locked loop or is a separate waveform synthesizer.
