Sensorless Controller For Electrostatic Machine
WARF: P200015US01

Inventors: Daniel Ludois, Aditya Ghule, Peter Killeen

The Invention
A variable speed drive for an electrostatic motor provides feedback control according to rotor position and/or rotor rotational rate deduced from back currents (back-MMF). Extraction of the back currents is performed by a modeling of the stator and the development of isolated stator voltages from plate voltage measurements.
