<P>PROBLEM TO BE SOLVED: To provide an installation method of a stator core of an electric motor capable of attaching the stator core to the inner periphery of a core holder without difficulty and regulating the axial movement of the stator core for the core holder even by the heat deformation of the core holder or the stator core. <P>SOLUTION: An installation method in which a stator core 41 of an electric motor is installed on the inner periphery of a core holder 44 includes a step of engaging the outer peripheral part of the stator core with a recess 37 formed in a cylindrical part 44a of the core holder. The recess is partitioned by a first wall 37a, a second wall 37b, and bottom part 37c, and the distance between the first wall and the second wall in room temperature is set so that the outer peripheral part of the stator core is engaged in the recess. <P>COPYRIGHT: (C)2012,JPO&INPIT |
