SWITCHED RELUCTANCE MOTOR CONTROL SYSTEM AND SWITCHED RELUCTANCE MOTOR CONTROL METHOD

摘要

An SR motor control system 10 includes: an SR motor 1, a driver circuit 2 having FETs 31 to 34 for adjusting an energization timing to an excitation coil 4 of the SR motor 1, and an energization control part 3 that controls ON/OFF of the FETs 31 to 34. The SR motor 1 has a supply mode in which the excitation coil 4 is energized and a regenerative mode in which electromotive force generated in the excitation coil 4 is recovered. The energization control part 3 has a synchronous rectification part 21 that determines an end time of the regenerative mode based on a current value of the excitation coil 4 during the regenerative mode.
