Prof. Akira Chiba – Recent Developments of Switched Reluctance Motors for Hybrid Electrical Vehicles

August 16 @ 2:10 pm - 3:00 pm

Abstract:

This seminar explains how switched reluctance machines are a promising alternative to permanent magnet machines for hybrid electric vehicles. It begins by describing recent developments in hybrid electric vehicles and explaining their principles of operation.  Rare-earth permanent magnet (PM) machines are commonly used in hybrid vehicles however the cost of magnets has seen considerable fluctuation in recent years. The characteristics of rare-earth PM electrical motors and generators of a leading hybrid vehicle are presented. The key criteria for switched reluctance motors to be competitive to rare-earth PM motors are then discussed. Some possible breakthrough solutions are presented. In addition, a novel method to reduce vibration and acoustic noise is presented. The generator operation and its loss reduction by switched reluctance machines are also presented.

Speaker:

Prof. Akira Chiba, Tokyo Institute of Technology, Japan, is a leading international expert on electric machines.  His research includes magnetically suspended bearingless ac motors, super high-speed motor drives and rare-earth-free-motors for hybrid and pure electrical vehicles.  He has published nearly 1,000 technical papers.  He has won numerous prize paper awards and has been actively involved in the IEEE in many roles over the years.
