Patent ID: 7498762

Claim:
A motor comprising: a stator in which an armature winding is wound around a slotted stator iron core via an insulator; a rotor rotatably disposed confronting the stator; a drive circuit disposed on a board, the drive circuit controlling a current applied to the armature winding and rotation of the rotor; and a capacitor which is at least one of a first capacitor and a second capacitor disposed on the board, the first capacitor smoothing a voltage supplied to the armature winding, and the second capacitor smoothing a supply voltage supplied from outside; wherein the board and the stator are integrally molded in using resin for forming a cover, and the drive circuit includes a group of switching elements for supplying the current to the armature winding and a drive logic controller for controlling on and off states of the group of switching elements, wherein the capacitor includes a wound element, in which an anode foil and a cathode foil are wound, housed in a cylindrical metal case having a closed top face, and sealed with a sealing rubber, which capacitor also includes an anode lead terminal and a cathode lead terminal both extending through and protruding from the sealing rubber; wherein the capacitor is mounted upright on the board and fixed to the board by applying an adhesive at two diagonally opposite areas on a bottom end of the metal case with resin existing between the sealing rubber and the board, wherein a gas outlet is provided near a top face of the capacitor.
