Numerical analysis of oil cooled PMSM jacket with horizontal strips design

Abstract

Cooling has been an important parameter to extend the high speed generator operating condition. Literature highlights the jacket of generator is a crucial part that need to be cooled down to dissipate the coil temperature to ensure the performance of the Permanent magnet synchronous machine (PMSM). Research shows there are work done on the internal jacket design to improve cooling. This research work focus on more design parameters for the internal oil flow jacket space design to dissipate heat better. The horizontal strips with straight and angled configurations were deployed to investigate the effect of heat transfer with constant cooling medium, Oil. The numerical analysis using ANSYS-FLUENT was completed, converged and mesh independent results were presented. The innovation in horizontal strips has shown to improve in heat transfer rate more than double form the bassline design. This will be used as base for future investigation for jacket cooling for high speed PMSM.
