Title: Commutator of rotating electric machine and method for manufacturing same
Inventor: TAKEUCHI TOSHIMI
IPC: H02K15/02
Filed: 2003-01-10
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a method for manufacturing a commutator of a rotating electric machine which can stabilize a frictional change to a brush by reducing the occurrence of a "plucking" or "chip welding" on the peripheral surface of the commutator, which reduces the slipping sound (brush sound) of the brush, and which can prolong the lifetime of the brush and to provide the commutator of the rotary electric machine.  <P>SOLUTION: The commutator is manufactured by cutting to finish the peripheral surface of the commutator by a cutting tool formed of a single crystal diamond with a round shape at the distal end of a cutting edge. Thus, since the peripheral surface of the commutator is cut so as to so-called "scoop" in parallel with the crystal grains of a cylindrical base material, the crystal grains to be sheared in the case of cutting are little, and the "plucking" is little on the peripheral surface of the commutator. Further, the cuttings generated in the case of cutting are hardly curled in a small radius. The generated cuttings are hardly entangled in a gap between the cutting tool and the peripheral surface of the commutator. The "chip welding" on the peripheral surface of the commutator is little. Accordingly, at the brush sliding time, the material of the brush is prevented from being irregularly deposited, and the frictional change with the brush can be stabilized.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
