This paper presents a novel configuration of the permanent magnet system for rotating magnetic refrigerator, which consists of stator and rotor. The stator of this system includes two permanent magnets and iron yoke. The rotor includes shaft, iron core and magnetic refrigerant material. When the magnetic refrigerant material is located under the pole of the permanent magnet, it is magnetized by a...
Rotor losses of axial flux permanent magnet (PM) synchronous machines with fractional windings depend on stator magneto-motive force (MMF) harmonics. To reduce rotor losses, a soft magnetic composite rotor can be used. This paper focuses on the comparison between two machines with the same soft magnetic composite stator and different rotor cores: one of solid steel and another of soft magnetic composite...
In this paper the flux linkage between the permanent magnets in the rotor and the stator core of a Transverse Flux machine is investigated, with a special focus on the flux concentrating setup, which allows to utilize the core materials up to their saturation limits. FEM simulations are carried out to find the relation between the flux linkage and the size of the permanent magnets. Finally new design...
