Abstract

PURPOSE: To reduce damage due to arc and lengthen the lifetime of a motor, by slitting the central parts of noble metal strips provided at an equal spacing on a clad metal plate so that the noble metal strips are left on its surface which slides on brushes.
CONSTITUTION: A clad metal plate 1 is wound as a cylinder A. Both the side edges of the cylindrical plate are located near each other so that a gap 6 almost equal to each slit 3 is defined. A molded resin 7 such as nylon is provided in the center of the metal cylinder. A shaft hole 8 is provided through the center of the resin 7, thereby forming a unit. The slits are manufactured in the central parts of noble metal strips 2 on the peripheral surface of the unit by a cutter. The noble metal strips 2 are located on both the sides of each sliding part 4, which slides on brushes. One end section of the sliding part 4 extends as a connection member 5. The adjacent sliding parts are electrically insulated from each other by the resin 7. As a result, damage due to arc caused by the sliding of the parts 4 on the free ends of the brushes is reduced and the lifetime of a motor is lengthened.
