What is PD IEC/TR 62518 - Rare earth sintered magnets properties at elevated temperature about?
PD IEC/TR 62518 is a technical report on 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 in open circuit flux that 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 PD IEC/TR 62518. The effect of length to diameter ratio (L/D) of the magnet samples and the influence of HcJ on the flux loss was also studied. The results are discussed in PD IEC/TR 62518.
Note: The temperature stability correlated with the complex corrosion behaviour and the spin reorientation phenomena at cryogenic temperatures will not be given in PD IEC/TR 62518.

Why should you use PD IEC/TR 62518 - Rare earth sintered magnets properties at elevated temperature?
SmCo5 was the first sintered rare earth magnet to be developed (1967) [1] 1, followed by Sm2Co17 [2, 3, 4] and Nd-Fe-B [5]. These magnets are used in a wide variety of applications. Recently, these magnets have been used in higher temperature applications such as in heavy duty permanent magnet motors.
Therefore, the subject of PD IEC/TR 62518 will be of considerable interest to the manufacturers of this type of motor and the developers of permanent magnet materials.
Using PD IEC/TR 62518 best practice guidance can increase the credibility of the equipment, quality assurance, durability, and safety.
