Comparative study of the mechanical properties of sinterized magnetic alloys applied to electrical machines' core

This paper aims at making a comparative study of some soft magnetic material alloys, which are likely to be used in the construction of rotative electrical machines' core or electrical motors. Therefore, this study focus on the building of massive cores, obtained from the conventional powder metallurgy process, also known as sinterized materials. The mechanical properties of hardness and yield stress are analyzed and compared, resulting in an increase of hardness and yield stress due to the influence of diffusion among the elements utilized in the alloys.

When the Powder Metallurgy processes are used, it is possible to build these in only one massive block, with a high magnetic permeability (which is an aspect of magnetic steels) and a high electrical resistivity, thus reducing the stray currents.According to the results of Table 4, for the application of these alloys as magnetic core, the samples were characterized in terms of their mechanical properties looking assign these materials to use as a basis for making these massive core electrical machines.Figure optionsDownload as PowerPoint slide
