Abstract

Temperature degrading of magnet material is of mayor interest in many applications. Segmented rare earth Halbach arrays are subject to an augmented temperature degrading effect due to local demagnetisation. This paper presents results using a parameter-based material demagnetisation model. Measurement results of high temperature Halbach arrays are validated with 2D FEA.
