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 machines(More)
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)
This paper describes a robust, modular, complete GPU architecture—the Tile-Load-Map (TLM)—designed for the real-time visualization of wide textured terrains created with arbitrary meshes. It extends and completes our previous succinct paper Amara et al. (ISVC 2007, Part 1, Lecture Notes in Computer Science, vol. 4841, pp. 586–597, Springer, Berlin, 2007) by(More)
This paper describes the state of the art of hybrid excitation synchronous machines. Different hybrid excited synchronous structures from scientific and technical literature are described and analysed. Advantages and drawbacks of the different structures are discussed. Different method of classification of these structures will also be discussed. The(More)
In this paper an analytical model for prediction of the no-load magnetic field in axial field flux switching permanent magnet machines (FSPM) is presented. The proposed method is based on an exact 2D analytical solution of Maxwell's equations in low permeability regions (stator/rotor slots, air gap, permanent magnets (PMs) and surrounding air regions),(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 of(More)
