Variable Magnetization Machine Controller
WARF: P140171US01

Inventors: Robert Lorenz, Brent Gagas, Takashi Fukushige, Takashi Kato

The Invention
A variable magnetization machine control system comprising a controller configured to adjust a d-axis current waveform and a q-axis current waveform in accordance with an operating condition of a variable magnetization machine to generate an adjusted d-axis current waveform and an adjusted q-axis current waveform that provide a driving voltage to drive the variable magnetization machine at a predetermined speed while maintaining the driving voltage below a predetermined maximum magnitude.
