High Speed Permanent Magnet Generator Material Investigations--Rare Earth Magnets
Abstract
Permanent magnets with room-temperature energy products of approximately equal to 20-30 MGOe were characterized with a view toward their use in airborne electrical machinery. This report presents the results of an evaluation of commercial sintered rare earth-transition metal magnets potentially suitable for such applications. They include SmCo5, (SmPr)Co5, and modified Sm2Co17, produced by 11 companies worldwide. Extensive magnetic, physical, mechanical, and electrical property engineering data, based on statistically significant numbers of test magnets for each measurement, are presented. Testing procedures, range of evaluation, and test considerations relevant to the application are also identified.
