Summary:An electric motor provided with: a stator which is configured by integrally molding stationary members using an insulating resin, the stationary members including stator cores on which stator winding wires are wound; a rotor which is disposed about the shaft so as to face the stator; two bearings which rotatably support the shaft; brackets which affix the bearings; and a drive circuit board which causes an electric current to flow to the stator winding wires and on which a drive circuit for driving the rotor is mounted. The outer ring and the inner ring of either of the two bearings are electrically insulated from each other. L'invention porte sur un moteur électrique qui est pourvu : d'un stator configuré par moulage en une seule pièce d'éléments stationnaires à l'aide d'une résine isolante, les éléments stationnaires comprenant des coeurs de stator sur lesquels sont enroulés des fils d'enroulement de stator; d'un rotor disposé autour de l'arbre de façon à faire face au stator ; de deux paliers portant l'arbre de façon rotative ; de supports qui fixent les paliers, et d'une carte de circuit de commande qui fait circuler un courant électrique vers les fils d'enroulement de stator ou sur laquelle est monté un circuit de commande destiné à commander le rotor. La bague extérieure et la bague intérieure des deux paliers sont électriquement isolées l'une de l'autre.
