Comparison of stator core lamination material and powder magnetic material for use in automotive alternators

摘要

The purpose of this study was to conduct a comparison between typical stator core lamination material and power magnetic material. Extensive laboratory testing has been conducted for different frequencies and applied field current levels. Theinduced flux density and field strength characteristics of the two magnet materials were then compared at various field current and rotor speed. In this paper, for alternative alternator technologies are also discussed.
