Title: Armature of rotating electric machine
Inventor: NIIMI MASAMI
IPC: H02K23/00
Filed: 2002-12-05
Abstract: <P>PROBLEM TO BE SOLVED: To facilitate an increase in output by reducing the electric resistance of an armature coil, and to provide an armature 4 of a rotating electric machine 1 that can shorten a machining process.  <P>SOLUTION: Each outside coil end 14b of an outside conductor 14 is formed so as to be gradually increased in sectional width (thickness) in the axial direction toward the inside diameter side from the outside diameter side, and its cross section is uniformly formed toward the inside diameter side from the outside diameter side. The anti-core side face of one outside coil end 14b in the axial direction is used as a rectifier face 14c. By this configuration, the electric resistance is reduced and the output is increased when compared with an armature coil using a conventional outside coil end that decreases in cross section toward the inside diameter side from the outside diameter side. In addition, since the center of gravity of the outside coil end 14b is shifted to the inside diameter side when compared with the conventional outside coil end, a centrifugal force acting on the center of gravity is reduced. As a result, resistance to centrifugation is improved, thus providing the armature 4 that withstands higher rotation.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
