<P>PROBLEM TO BE SOLVED: To provide a motor with a brush comprising a rotor which is rotatably stored inside a stator containing a permanent magnet. <P>SOLUTION: A magnet insert hole (4d) has a flux barrier part (4e) which regulates the shorting of magnetic flux between both poles of one permanent magnet (5) on the side adjoining a magnetic pole part (4a), adjoining each other. An interval between an end part on the side adjoining the magnetic pole part of the flux barrier part (4e), adjoining each other, and an end part on the side adjoining the magnetic pole part of the magnetic pole part (4a), adjoining each other, is θw≤0.7°, where an angle θw is based on the center of rotational axis of a rotor (9). <P>COPYRIGHT: (C)2013,JPO&INPIT |
