Generally, accurate modelling of electrical machines requires the use of finite-element method. However, FE analysis is too time consuming, especially at firsts design stages, from the point of view of engineers working in R&D departments in the electrical machine industry. To reduce pre-design stages duration, analytical models are often preferred. Two(More)
—In this paper, the suitability of a class of electric machines for vehicle traction applications is discussed. These machines, which are known as hybrid excitation synchronous machines , combine permanent-magnet (PM) excitation with wound field excitation. The goal behind the principle of hybrid excitation is to combine the advantages of PM excited(More)
The aim of this paper is to present a method and a tool to extract the full set of information from an animated character designed in Maya (animatable body only). The Maya plug-in generates the appropriate data as specified in the MPEG-4 FBA standard [2]. The result is composed of three different data sets: the BDP (Body Definition Parameters) describing(More)
—This paper deals with the computation of vibrations and noise of electromagnetic origin for 'U'-shaped stator core flux switching permanent magnet (FSPM) machines. The investigation concerns a family of FSPM stator/rotor configurations with 12 slots and 10, 11, 13, and 14 rotor poles. More precisely, the study focuses on the influence of different number(More)
In this work we present two approaches to improve the " Collision Avoidance " mechanism of the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol. Our first approach : the " Uniform Law with Doubling Interval CSMA/CA (ULDI_CSMA/CA) " uses a uniform law in an interval of values I=[a, b] to calculate the random starting time when(More)
