Abstract

A stator for an electrical machine comprises a laminated core 3 and a respective end shield 1,2 secured at each end of the core. In order to align the co- operating end faces of the shields and the core in parallel relationship, in a simple manner, the end faces of the core are formed with depression 31, 33, 37, 38, 39 to afford abutment surfaces, 311, 331, 371, 381, 391 with which respective bearing surfaces of the end shields 1, 2 co-operate. The depressions may be formed advantageously by directly upsetting the end faces of the pre-assembled core 3. The invention is particularly applicable to stators of non- enclosed electric motors. <IMAGE>
