ICEMS2017 Keynote Presentation
Development of Switched Reluctance Motors
for Hybrid Electrical Vehicles
In this presentation, the high efficiency automotive drives are reviewed. An example of operations of a hybrid vehicle, Toyota Prius, has been reviewed. The motor specifications and requirements are presented. To reduced or eliminate rare-earth material, in a project of rare-earth-free motors, a switched reluctance machine has been introduced. The problems related to the improvement of torque density and efficiency and reduction of noise and vibration are discussed.
