Fastening structure of rotor core to shaft of motor

摘要: PROBLEM TO BE SOLVED: To provide a fastening structure of rotor core to shaft motor which are attached relieving stress in direction an axial center, is generated when the press fitted. SOLUTION: In motor, plurality thin steel plates with throughholes formed laminated form then fitted fitting hole at center attach, 2a 2 so that smaller diametrical portions r1 and larger r2 may be alternately along circumferential direction, 1 direction. The 4 recessed protruded 4a on outer peripheral face into 1a attach. COPYRIGHT: (C)2006,JPO&NCIPI
