Abstract:
1. A switched reluctance motor comprising: a stator including: a rotor rotatably inserted inside the exterior member of the stator; a rotary shaft coupled to the rotor; a phase indication magnet coupled to the rotor or the rotary shaft; at least one sensor mounted at one of the salient poles and sensing a phase of the phase indication magnet; a sensor substrate connected to the sensor; and a parking magnet mounted at another salient pole facing the salient pole mounted at the sensor, for stopping and positioning the rotor at an effective torque generation area together with the phase indication magnet, wherein the cylindrical-shape exterior member is formed by molding the cylindrical body, the salient poles, the parking magnet, the sensor and the sensor substrate so as to encompass the cylindrical body, the salient poles, the parking magnet, the sensor and the sensor substrate having been assembled.
