Manufacturing-oriented magnetic analysis of segmented stator lamination stacks

Increasing the knowledge about components used to assemble an electric drive becomes more and more crucial. Especially for efficient electrical drives, that are produced in large volumes, it becomes necessary to know, how build in components like electrical steel stacks of stator and rotor perform. For the latter, their magnetic behavior is primarily responsible for an electric drive’s overall performance. Hence, a magnetic measurement device has been designed and built to further investigate net shape parts regarding production-related magnetic property variations. Within this paper, a detailed insight in the design of a net shape part measuring setup for segmented stator teeth is given. The measurement system is validated concerning its ability to perform repeatable measurements of the same part geometry. The small measurement deviation allows to further investigate variations in testing conditions like the applied mounting pressure. To give an outlook on the future field of application of such measurement systems in large volume production lines, an investigation of parts produced from different batches indicates the range in which magnetic properties of final parts vary.
