Rare earth sintered magnets - Stability of the magnetic properties at elevated temperatures

PUBLISH DATE 2009

Rare earth sintered magnets are crucial for various high-performance applications due to their strong magnetic properties.

Stability of the magnetic properties at elevated temperatures is a key factor in determining their reliability and effectiveness in demanding environments.

IEC/TR 62518:2009(E) describes the temperature behaviour of rare earth sintered magnets in detail for use in designing magnetic circuits exposed to elevated temperatures. The temperature behaviour of SmCo5, Sm2Co17 and Nd-Fe-B sintered magnets is described.

The various changes of open circuit flux which can occur due to temperature are discussed in Clause 4. The long term stability of the magnets is discussed in Clause 5. The experimental procedures are described in Clause 6.

Results of the measurements of the flux loss occurring at the ambient temperature after heating isothermally at 50 ¦C, 75 ¦C, 100 ¦C, 125 ¦C, 150 ¦C and 200 ¦C for up to 1000 h are given in Clause 7. The effect of length to diameter ratio (L/D) of the magnet samples and the influence of HcJ on the flux loss were also studied. The results are discussed in Clause 8.

The data in this technical report was provided by the Institute of Electrical Engineers of Japan (IEEJ) and its subcommittees. This data has been gathered from the members of these sub-committees.

The temperature stability correlated with the complex corrosion behaviour and the spin re-orientation phenomena at cryogenic temperatures will not be given in this technical report.
