Modelling of Eddy-current Losses in a Surface-mounted Ndfeb Permanent-magnet Generator
In a surface-mounted sintered NdFeB permanent-magnet generator, the magnets are usually thin (typically 4 mm), and hence the armature reaction, due to the time harmonics in the stator currents, is high. NdFeB magnets are conducting (resistivity typically 1.6 μΩm) and experience eddy-current losses. Therefore, the combined eddy-current losses in the NdFeB magnets and a solid iron rotor may becom...
متن کاملField Diffusion Equation in High-speed Surface-mounted Permanent Magnet Motors, Parasitic Eddy-current Losses
The authors present a general computation of the time-varying magnetic flux density distribution of high-speed surface mounted permanent magnet (PM) motors (SMPMM). It deals with an analytical model (AM) which is based on a two-dimensional (2-D) analysis in polar co-ordinates and solves the governing Helmholtz/Laplace field equation in the airgap/magnet/rotor yoke regions, with due account of t...
متن کاملModeling and analysis of eddy current losses in permanent magnet machines with multi-stranded bundle conductors
This paper investigates the influence of eddy current losses in multi-stranded bundle conductors employed in outrunner permanent magnet machines, by adopting an analytical model. The analytical model is based on a sub-domain field model that solves the two-dimensional magnetostatic problem using the separation of variables technique for each of the non-magnetically permeable machine sub-domains...
متن کامل3D Calculation of the Eddy-Current Losses in the Beam Tube of the SIS100 Dipole Magnet
The eddy-current losses in a simplified model of the SIS100 dipole magnet (Fig. 1a) comprising the elliptical beam tube are calculated. The standard 3D Finite Element (FE) formulation is augmented by a shell element representation of the thin beam tube. Using this approach, the mesh construction can be restricted to the beam tube surface and the outer parts, avoiding the construction of element...
متن کاملModeling of Eddy Current Loss and temperature of the magnets in Permanent magnet Machines
The eddy current loss in the magnets of permanent magnet (PM) motors in a hybrid electric vehicle (HEV) and plug-in HEV is usually not taken into consideration in traditional motor design and analysis. However, due to the high conductivity of the rare-earth magnet, neodymium-iron-boron (NdFeB), and slot/tooth harmonics, there is eddy current loss generated inside the magnets. This loss may not ...
