Electric motor includes stator, rotor, a pair of bearings, outer-ring conducting part, and printed circuit board. Outer-ring conducting part electrically couples outer rings to each other that are included respectively in the pair of bearings. Printed circuit board includes drive circuit and an impedance element. Drive circuit includes ground line. Drive circuit controls an electric current that flows through stator winding. The impedance element is formed with at least not smaller than one pair of conductive patterns. One of the conductive patterns forming the impedance element is electrically coupled with outer-ring conducting part. The other of the conductive patterns forming the impedance element is electrically coupled with ground line included in drive circuit.

A method for forming an electrical connection structure part according to the present invention includes a step of covering, with an alloy body, a connection part between a first conductor part and a second conductor part, so as to form the electrical connection structure part. The first conductor part contains aluminum. The second conductor part has a surface covered with an ingredient containing nickel. The alloy body contains tin, silver, and nickel. The method further includes steps of: connecting the first conductor part and the second conductor part to each other to form the connection part; melting the alloy body; and dipping at least the connection part into the molten alloy body.

The mold commutator of the present invention comprises a plurality of commutator segments made of copper or copper alloy and circumferentially arranged, a plurality of spark absorbing elements, disposed between adjacent commutator segments, with paired parallel surfaces respectively having electrodes thereon, and a resin mold portion which integrates these portions into one piece. The spark absorbing element is electrically connected to the commutator segment via the electrode, and spark voltage generated at the commutator segment is absorbed by current flowing between the electrodes.

A motor bearing device includes a bearing member, and a rotary shaft made of steel into which ions of metal element and carbon ions are implanted via a surface of the rotary shaft. The rotary shaft is slidable relative to the bearing member. The metal element is selected from the group consisting of metal elements in the IVa, Va, and VIa groups of the periodic system. Lubricant is provided between the bearing member and the rotary shaft. The surface of the rotary shaft opposes the bearing member.

A method of recovering resources in a resin-molded electrical rotating device (1,2) in which electromagnetic members (1a,1b,2a) are molded with resin molding (1c,2c) with fine voids so as to be integrally made into a solid body, and a resin for molding of the rotating device (1,2). The method has the steps of disintegrating the resin molding (1c,2c) by chemically decomposing and/or eluting so as to remove the resin molding (1c,2c) from the electromagnetic members (1a,1b,2a) and separating and recovering at least metal components in the electromagnetic members (1a,1b,2a) as the resources.

A lining material superior in abrasion-proof, considerably reducing the sliding sounds to be caused at high speeds, and an ultrasonic wave driven motor using the lining material (9) for the inverted face of a rotor (2). The lining material is composed of total aromatic polyamide pulp granule of a meta type and/or total aromatic polyamide fiber of a meta type as main comonents, being 3 through 40% in the percentage of voids. As the lining material (9) is used as the inverted face of the rotor portion (2) which comes into contact against the vibration amplifying portion (5) of the stator portion (1), so that the noises during the driving operation may be reduced, and also, the service life of the inverted face may be extended.
