Abstract

Rare-earth permanent magnets (REPMs) are central to the electromagnetic energy conversion process in permanent-magnet synchronous and flux-switching machines. To design the magnetic circuit and a magnetizing circuit for post-assembly magnetization, it is indispensable to describe the magnetization behavior of the REPMs accurately. Commonly, simplified models are used that are often not capable to replicate the non-linearity, magnetic hysteresis, and magnetic anisotropy. In this paper, four different REPMs are methodologically characterized by using a pulsed-field magnetometer. Their first-order return curves and magnetization behavior, starting from the virgin state, are recorded and used to parameterize and validate two different pragmatic hysteresis models.
