Cost and performance trends of permanent magnets in automotive applications

The author discusses the cost and performance comparisons of permanent magnets covering BHmax (e.g. for sensors and loudspeakers), figure of merit (e.g. for motors), influence of Chinese production on cost and new permanent magnet materials. The author discusses the following automotive applications: effect of temperature, dual voltage, PM motors, modular systems, X-by-Wire, and alternator design. (26 pages)
