Abstract:
1. An electric motor comprising: a stator having a stator iron core and a winding wound thereon molded together by a layer of resin mold; a printed wiring board with a drive circuit mounted thereon for energizing the windings, no part of the printed wiring board being molded in the resin mold; a rotor comprising: a pair of bearings for journaling the shaft; two conductive brackets for fixing the pair of bearings, respectively; a conducting member electrically connecting the two brackets to each other, wherein the conducting member runs inside the layer of resin so that the conducting member is electrically insulated from the stator iron core, and no part of the conducting member is in physical contact with the printed wiring board; and a dielectric layer being formed in the rotating body between the shaft and an outer periphery of the rotating body.
