Manganese-based Permanent Magnets
There is a significant gap between the energy product, BH, where B is the magnetic flux density and H is the magnetic field strength, of both the traditional ferrite and AlNiCo permanent magnets of less than 10 MGOe and that of the rare earth magnets of ...

Development of a torsional vibration suppression device using permanent magnets
Dual mass flywheel (DMF) dampers are conventionally used for torsional vibration suppression in automobile powertrains. The torsional vibration in powertrains has increased in recent years owing to the widespread downsizing of internal combustion engines

Characterization of Permanent Magnet Magnetization [PDF]
The performances of electrical machines highly depend on the behavior of materials, such as steel, copper, and permanent magnet. This paper focuses on permanent magnets whose magnetization must be precisely known. Thus a non-destructive approach which includes a combination of experiments and inverse problem, using the magnetostatic moment method, is ...

Hysteresis Loss in NdFeB Permanent Magnets in a Permanent Magnet Synchronous Machine
Most permanent magnet (PM) loss studies consider only eddy current loss and neglect hysteresis. In this article, the hysteresis behavior of two NdFeB PM grades with different magnetic properties is assessed when applied in a PMSM. Data from vibrating sample magnetometer measurements and hysteresis modeling are used as a base.
