Abstract: A miniature motor including a housing formed into a bottomed hollow cylindrical shape, on the inner circumferential surface of which a permanent magnet is fixedly fitted; A rotor is provided having an armature, a spark-quenching element and a commutator. An end bracket is provided having brushes fitted to the open end of the housing and making sliding contact with the commutator. Input terminals are electrically connected to the brushes; The rotor is rotatably supported by bearings provided on the housing and the end bracket, in which the spark-quenching element is formed by a laminated ceramic capacitor formed into a ring shape, having on the outer surface thereof the same number of electrodes as the number of poles of the armature; The electrostatic capacity of the capacitor is more than 1 .mu.F.
