The invention relates to a sheet metal part or sintered part (10) for a stator or a rotor of an electrical machine, for example an electric motor, and to a method for producing said sheet metal part or sintered part (10). The sheet metal part or sintered part comprises a connecting piece (11) from which regularly spaced apart teeth (12) project. At the free end, every tooth (12) has a tip (14) which is connected to the connecting piece (11) via a web (13). Every tooth has at least one first tooth segment (22) and at least one second tooth segment (23). The tooth segments are produced from different magnetizable materials (M1, M2). In this way, the materials (M1, M2) can be specifically used in terms of their magnetic and/or mechanical properties in the region of the tooth (12) where they can optimize the magnetic and/or mechanical behavior of the tooth (12) and thus of the sheet metal part or sintered part (10). In particular the tip (14) has at least one first tooth segment (22) the saturation magnetization (BS1) of which is higher than that of the remaining sheet metal part or sintered part (10). |
