Axial Flux Permanent Magnet Machines benefit from manufacturing advantages and reduction in end winding length through the use of tooth-concentrated fractional windings but display increased space harmonic content, leading to higher eddy current losses in the rotor iron and permanent magnets. The choice of a double layer tooth-concentrated fractional winding for the modeling and design of a 24 ...

The higher specific torque and power density of a transverse flux permanent magnet (TFPM) machine in comparison to a conventional machine makes it a promising direct-driven wind turbine generator. The new topology presented in this paper is believed to have a better utilization of the available in the nacelle space. This would favor a reduced inactive weight of the generator and thus remove one...

The transverse flux machines (TFM), introduced at the beginning of the 80’s, are possible solutions for diverse applications requiring special electrical machines [1]. The researches have focused until now mainly on rotary TFMs. A new type of permanent magnet linear transverse flux reluctance machine is proposed here. Such machines can be successfully applied for example in conveyor application...

This paper proposes a novel axial flux switching permanent magnet generator for small wind turbine applications. Surface mounted axial flux switching permanent magnet (SMAFSPM) machine is a new type of these machines that is introduced in this paper. One of the most important challenges in optimal designing of this kind of machines, is ease of construction and maintenance. One of the main featu...

In this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3D finite element modeling and experimental tests. The structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

This paper reports the design, fabrication, and testing of a permanent-magnet energy harvester generator for body motion. The described generator was capable to extract up to 117μW of power from walking, employing a non-resonant rotational mechanism. The planar generator proposed is composed of a rotor having multiple NdFeB permanent magnet pole-pairs with an eccentric proof mass. The stator ha...

The conventional linear permanent magnet generator (CLPMG) for direct-drive wave energy conversion (WEC) has experienced many drawbacks that are difficult to overcome such as low power density and bulky system volume. To improve power density, this paper proposes a linear magnetic-geared interior permanent magnet generator (LMGIPMG) with tubular topology, which artfully incorporates a linear ma...
