Laminate for plate packet of electrical machine, has circular symmetrical region within outer peripheral line that extends beyond radial plane in axial direction when laminate not mounted on electric machine shaft

摘要

The laminate (1) is mounted on a shaft (5) of an electrical machine in an axial direction (3) and has an outer peripheral line spanning a radial plane (33). A peripheral, circular symmetrical region (11) of the laminate within the outer peripheral line extends beyond the radial plane in the axial direction when the laminate is not mounted on the shaft.
