PURPOSE: A motor is provided to prevent the degradation of the magnetic flux density by forming a plurality of rivet holes on an edge. CONSTITUTION: A stator is arranged inside a housing. A stator coil is wound around teeth of the stator. A rotor(300) is arranged inside the stator. The rotor generates the rotation force by the magnetic flux with the teeth of the stator. The rotor has a shaft hole(301), a plurality of magnet insertion holes(302), and a plurality of rivet holes(330). A rotary shaft is fixed in the shaft hole. Two permanent magnets(350) are inserted into one magnet insertion hole. A plurality of rivet holes are dispersedly arranged to the circumference direction. |
