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.

摘要: A switched reluctance machine has salient poles on the stator and rotor. The windings of the machine are supplied from a converter which provides energisation at a chosen rate. The windings of the machine may be energised at the rate at which the rotor poles pass the stator poles, or it may be operated at a fraction of that rate by energising the windings to cooperate with every second, third or fourth rotor pole. This can extend the output of the machine.
