Title: Motor and manufacturing method
Inventor: OBARA RIKURO
IPC: H02K7/08
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a motor and its manufacturing method which can avoid the unnecessary deformation of a sleeve hole (inner circumferential wall) caused by a force for press-fitting of a sleeve (sleeve press-fitting force) and make the assembly work easy to improve the productivity. SOLUTION: An annular recess 26 (relief recess) is formed on the inner circumferential wall of the center cylinder 20 of a flange main part 6. When a sleeve main part 9 is press-fitted into the hole (sleeve coupling hole 6a) of the flange assembly 51 to unify them, as the annular recess 26 is provided in the hole of the flange assembly 51, a coupling area between the sleeve main parts 9 and 6 is reduced. A whole press-fitting force applied to the coupling part, therefore, is reduced and the deformation of the inner diameter part 7a of the sleeve main part 9 caused by the press-fitting of the sleeve main part 9 can be reduced, so that the deformation of the inner diameter part 7a of the sleeve main part 9 and the deformation of the flange main part 6 can be suppressed.
