摘要： The rotor position detection apparatus Y is applied to an SR motor 10 comprising a stator 12 which is provided with salient poles 11 (11a, 11b, 11c) corresponding to a plurality of phases, each salient pole 11 (11a, 11b, 11c) provided with an excitation winding 15a, 15b, 15c and a rotor which is disposed in the stator and provided with a plurality of salient poles 13. The rotor position detection apparatus comprises a micro constant current application unit (circuit) 23 which applies a micro constant current to the excitation winding, and a polarity inversion detection means X which detects polarity inversion of a magnetic flux appearing in the stator 12 of the SR motor 10, thereby detecting a salient pole opposed position through a magnetic flux polarity inversion position.

摘要： A rotor position detection apparatus (Y) is applied to a SR motor (10) including a stator (12) having salient poles (11a-11c) corresponding to a plurality of phases, each salient pole (11a-11c) having excitation windings (15a-15c), and a rotor (14) disposed in the stator (12) and provided with a plurality of salient poles (13). A magnetic flux detection means (X) is provided with a detection part in a position where a magnetic flux generated by a phase current in the stator (12) is detected. The apparatus (Y) includes a threshold value holding unit (21) holding the magnetic flux detected by the detection part as a threshold value, when the rotor (14) is located at a predetermined detection position; and a comparison unit (25) comparing a threshold value with the magnetic flux, wherein the apparatus (Y) detects that the rotor (14) has reached a predetermined position, based on the comparison result of the unit (25).
