Title: Characterization of Contact and Bulk Thermal Resistance of Laminations for Electric Machines

Technical Report ·
DOI:https://doi.org/10.2172/1215166· OSTI ID:1215166

The ability to remove heat from an electric machine depends on the passive stack thermal resistances within the machine and the convective cooling performance of the selected cooling technology. This report focuses on the passive thermal design, specifically properties of the stator and rotor lamination stacks. Orthotropic thermal conductivity, specific heat, and density are reported. Four materials commonly used in electric machines were tested, including M19 (29 and 26 gauge), HF10, and Arnon 7 materials.
