Distortion Response of Motor Axis with Permanent Magnet as Shrink Fitting

영구자석 여자전동기 회전부 축의 열박음에 따른 변형특성

Shrink fitting is often used to replace conventional mechanical fasteners and fastening methods. Localized heating of the mating surface provides temporary expansion and allows slip fit assembly. The resulting interference fit exhibits exceptional strength without surface deformation at ambient temperatures. We studied an analysing method to find out a deformation of motor axis with shrink fitting of thermal expansion.
