Abstract
A stator of a switched reluctance motor includes a stator core part, stator coiling parts, stator salient parts, and pairs of permanent magnets. The stator coiling parts protrude inwardly from the stator core part and have coils wound on an external side thereof. The stator salient parts protrude inwardly from the stator core part and are disposed between the stator coiling parts. Each pair of the permanent magnets is inserted into each of the stator coiling parts and magnetized in the same direction as a direction of a magnetic field generated by the excitation of the coils. This stator has an electromagnetic structure designed to prevent the reversal of a magnetic field generated by the excited coils. The output of the motor is enhanced by inserting the permanent magnets so as to be magnetized in the same direction as a direction of a magnetic field generated by the excited coils.
