Title:
ロータ位置検出装置及びモータ制御装置
Document Type and Number:
Japanese Patent JP6621306
Kind Code:
B2
Abstract:
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.
