Switched reluctance motor control device uses microprocessor providing control signals for switching transistors supplying DC voltages to stator phase windings in dependence on detected rotor position

摘要

The control device has a driver circuit (60) with a number of switching transistors (Q1-Q6), used for supplying a DC voltage to each stator phase winding of the switched reluctance motor, the control signals for the switching transistors provided by a microprocessor (80) in dependence on the detected rotor position provided by a position sensor (Sa), after an initial run-up phase in which the microprocessor provides a series of control signals for alignment of the rotor. An independent claim for a switched reluctance motor control method is also included.
