The uploaded data file is a part of data used or generated by a model proposed in a paper entitled: “A New Dynamic Stochastic EV Model for Power System Planning Applications”. The proposed model in this paper consists of two sub-models which are the travel behavior and the battery depletion sub-models. The proposed model is taken into consideration the different trip purposes, starting and ending trip times, as well as the corresponding battery depletion. The outcomes from the travel behavior sub-model are the starting times, the ending times and the trips distances.

Thiswork dealswith fractional-slot permanent

magnet synchronous machines (FSPMSMs) equipped with

phasesmade up of one coil parallel branches. These exhibit

attractive potentialities, especially their enhanced opencircuit

fault tolerance capability. Furthermore, these topologies

are suitably-adapted for low-voltage power supply that

makes them viable candidates for possible integration in

the 42V automotive technology. This potentiality is further

highlighted in battery electric vehicleswhere the passenger

The paper is aimed at a class of fractionalslot

permanentmagnet synchronousmachines (FSPMSMs)

equipped with phases made up of one coil parallel

branches, with emphasis on their potential to reject the

harmonic currents circulating in the loops created by the

parallel branches. Following the identification and topological

characterization of this class of machines in Part 1,

the star of slots approach is extended to the analysis of

the back-EMF harmonic content. This makes it possible the

The paper is aimed at an investigation of the effects of the mover eccentricity on the PM eddy current loss of tubular-linear synchronous machines (T-LSMs) equipped with quasi-Halbach magnetized PMs. The study is initiated by an analytical prediction of the no-load spatial repartition of the flux density taking into account the non-coaxiality of the mover and stator, and its validation by a 3D finite element analysis (FEA). Then a special attention is paid to an analytical formulation of the PM eddy current loss in presence of eccentricity.
