Slot Water Jacket Cooling System for Traction Electrical Machines with Hairpin Windings: Analysis and Comparison

This work aims to analyze and compare the electromagnetic and thermal behavior of two commonly used electrical machines in the automotive field: an induction motor and a brushless permanent magnet one, here equipped with slot water jacket cooling systems. The same stator design, drive management, and winding layout, with hairpin conductors, are adopted for both machines. Four different slot coolin...
