Performance study of a PMSM with molded stator and composite housing with internal slot cooling - resulting in high continuous power

Introduction of a permanent magnet synchronous machine (PMSM) with concentrated, upright flat wire windings. During over molding with a filled, high thermal conductive epoxy compound, cooling channels are created in the stator slots. This enables the use of a fiber filled phenolic resin for the housing, instead of a thermal conductive metallic housing, necessary for a cooling sleeve. Simulations and experiments on the testbench proof the performance of the concept.
