Abstract
A motor includes a drive circuit for driving a rotor by controlling a current applied to an armature winding of a stator, and a capacitor for smoothing a voltage supplied to the armature winding and/or a capacitor for smoothing a supply voltage from outside on a same board. The board and the stator are integrally molded in using resin. Prior to the molding, capacitors are sealed inside a cylindrical metal case with a closed top face by rubber, and a pair of lead terminals protrude outside through this sealing rubber. The capacitors are mounted upright on the board and fixed by applying adhesive at two diagonally opposite areas on a bottom end of the metal case.
