Laminations for laminated cores of rotary electric machines and method of manufacturing such laminations

摘要

The lamellas (2) for rotor and/or stator are constructed at least partly of partial ring segments (4) that are separated at least partly from an inner ejection part (2) that is left over as a residue after manufacture of the annular sheet lamellas. The partial ring segments can be of the same or different lengths and can be at any angle to the rolling direction. Independent claims are also included for the following: a method of manufacturing sheet lamellas.
