Abstract:
1. A switched reluctance motor, comprising: a stator; a rotor that rotates with respect to the stator centering around a rotational shaft; a sensor shutter that includes at least one sensing part through which a light passes, the sensor shutter being attached to an end portion of the rotational shaft; a stopping ringer attached to the end portion of the rotational shaft so as to prevent the sensor shutter from being separated from the rotational shaft, wherein a sensor shutter connector is formed at the end portion of the rotational shaft, the sensor shutter connector reducing in a radial direction to allow the sensor shutter to be attached to the end portion of the rotational shaft, wherein the stopping ring is attached to the sensor shutter connector, and wherein a concave-convex part is formed at the sensor shutter connector to prevent a gap in an axial direction of the stopping ring.
