摘要： The present disclosure relates to an assembly for the compensation of thermic expansion in an electric machine. Disclosed is an assembly for the compensation of thermic expansion in an electric machine with a stirrup connected to a support element mounted to a stator frame, the stirrup is suspended to the stator frame at one end and clamped to the keybar at the other end and projects with the support element perpendicular to the keybar, whereas a spring element or a damper element are pressed and reduce width when a gap between the stirrup and the keybar reduces size due to thermic expansion.
