Case study: Optimization strategy to balance material cost, efficiency and NVH of electrical motor for next generation VINFAST powertrain system

Vu Ha Hai

Director of Emachine and Transmission Design Center

In this talk, we will look at:

  • The current status of VF8 EDS round winding and reason needed to change hairpin winding.
  • Theory behind the optimization strategy: Simulation result validation, NVH theory, efficiency duty cycle, testing facility.
  • Optimization strategy demonstration: Work flow, Software, Input/Output
  • Post processing process to find the optimal design to balance three target criteria: Material Cost, Efficiency and NVH
