Switched reluctance motor and connection method for sensor shutter thereof

A switched reluctance motor comprising:

• a stator;
• a rotor rotating with respect to the stator centering around a rotational shaft;
• a sensor shutter having a sensing part through which a light can be passed and connected to the rotational shaft with a pre-set assembling position;
• a rib connected to the sensor shutter and then curved at the end portion of the rotational shaft so as to prevent the sensor shutter from being separated.

A connection method for a sensor shutter of a switched reluctance motor in which the sensor shutter having a sensing area for passing a light and a shaft hole at a center thereof is connected to one end portion of a rotational shaft of a rotor, the connection method comprising:

• forming a rib at the one end portion of the rotational shaft to be protruded in an axial line direction;
• connecting the rotational shaft to the sensor shutter so as for the rib to pass through the shaft hole;
• and
• fixing the sensor shutter by curving the rib.
