  • Publication number: 20220123608
    Abstract: A motor includes a stator that includes a stator core and coils. The stator core is formed of a magnetic material and has a plurality of teeth arranged at intervals in a circumferential direction. The coils are formed of electrically-conductive windings wound around the teeth. Moreover, the motor also includes a rotor having a plurality of magnets arranged in radial opposition to the stator core and at intervals in the circumferential direction. The rotor is configured to rotate upon supply of electric current to the coils. Furthermore, the motor also includes a plurality of pseudo-teeth formed of a magnetic material and each located in a circumferentially intermediate area between a circumferentially-adjacent pair of the teeth. The pseudo-teeth are arranged so as to be concentrated in a part of the stator core in the circumferential direction.

  • Patent number: 8368261
    Abstract: The present invention provides a motor (M) including a rotor (1), a stator (S) having a winding wire (2) wound thereon, and an outer cylinder (3) for holding the stator (S) fitted into the inner circumference thereof. The stator (S), the outer cylinder (3), and a terminal (4) having one end (4a) connected to the winding wire (2) are integrated together by a mold resin (12) by insert molding while closing one end side of the outer cylinder (3) by the mold resin (12), and protruding the other end (4b) of the terminal (4) out of the motor (M) through the mold resin (12).

  • Patent number: 8368262
    Abstract: The present invention provides a motor (M) including a case (1) storing an armature (3) having a winding wire (2) wound thereon on the inner circumferential side, in which the case (1) includes an opening part (1a) for inserting a terminal (5) for connecting the winding wire (2) to an external power source, and the terminal (5) is integrated into a resin for forming a cap (6) for air-tightly closing the opening part (1a) by insert molding, with one end (5a) of the terminal (5) being protruded into the case (1) and the other end (5b) of the terminal (5) being protruded out of the case (1).
