To provide a switched reluctance motor capable of continuing an operation in the occurrence of defect.SOLUTION: A switched reluctance motor comprises: a motor part (100) having a stator (110) having a projection pole (111), a rotor (120) having a projection pole (121), and a winding (112) with a plurality of phases, wound to the projection pole (111) of the stator (110); a switching part (300) supplying an excitation current to the winding (112) with the plurality of phases by conducting a switching element (SW); and a control part (200) controlling a conduction state of the switching element (SW). Each winding is structured by including a first winding (112u1, 112v1, and 112w1), and a second winding (112u2, 112v2, and 112w2). The control part (200) controls a mode supplying the excitation current to both of the first winding (112u1, 112v1, and 112w1) and the second winding (112u2, 112v2, and 112w2) in each phase and a mode supplying the excitation current to each of them.SELECTED DRAWING: Figure 1 【課題】不具合発生時に動作を継続できるスイッチトリラクタンスモータを提供する。【解決手段】突極（１１１）を有するステータ（１１０）、突極（１２１）を有するロータ（１２０）、及びステータ（１１０）の突極（１１１）に巻回された複数相の巻線（１１２）を備えるモータ部（１００）と、スイッチング素子（ＳＷ）の導通により複数相の巻線（１１２）に励磁電流を供給するスイッチング部（３００）と、スイッチング素子（ＳＷ）の導通状態を制御する制御部（２００）とを備え、巻線のそれぞれは、第１巻線（１１２ｕ１，１１２ｖ１，１１２ｗ１）と第２巻線（１１２ｕ２，１１２ｖ２，１１２ｗ２）とを備えて構成され、制御部（２００）は、各相の第１巻線（１１２ｕ１，１１２ｖ１，１１２ｗ１）と第２巻線（１１２ｕ２，１１２ｖ２，１１２ｗ２）との両方に励磁電流を供給するモードと、いずれか一方に励磁電流を供給するモードとに制御する。【選択図】図１
