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 technically pure copper is being replaced by aluminium as conductive material in electrical transformers for power systems. This evolution brings new manufacturing challenges. One major difficulty is the limited weld ability and non-acceptable residual deformations of the aluminium, when welded by fusion arc welding processes. The Friction Stir Welding (FSW) was selected for evaluation cons...

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...

The voltage control is performed by changing the turns ratio. This is done by provision of taps in the winding. The volts per turn available in large transformers is quite high and hence a change of even one turn on the LV side represents a large percentage change in the voltage. Also the LV currents are normally too large to take out the tapping from the windings. LV winding being the inner wi...

We study supermembranes in the light-cone gauge in eleven flat dimensions with compact directions. The membrane states are subject to only the central charges associated with closed two-branes, which, in this case, are generated by the winding itself. We present arguments why this winding leaves the mass spectrum continuous. The lower bound on the mass spectrum is set by the winding number and ...

To extract critical points from a (3D time-resolved) blood-flow velocity field, we employ a 3D winding number algorithm. Experiments are performed to asses the behavior of the winding number algorithm. First is experimented with artificial data sets, and the robustness of the winding number algorithm is tested, along with the indexation algorithm and the clustering algorithm. Subsequently, some...

We find the exact winding number distribution of Riemann-Liouville fractional Brownian motion for large times in two dimensions using the propagator of a free particle. The distribution is similar to the Brownian motion case and it is of Cauchy type. In addition we find the winding number distribution of fractal time process, i.e., time fractional Fokker-Planck equation, in the presence of fini...

Abstract In coreless filament winding, resin-impregnated fibre filaments are wound around anchor points without an additional mould. The final geometry of the produced part results from interaction fibres in space and is initially undetermined. Therefore, success large-scale composite structures for architectural applications relies on reciprocal collaboration simulation, fabrication, quality e...
