Abstract: In this paper, we present a methodology of design and modeling of the controlling parameters of synchronous motor with wound rotor, based on the analytical method. This methodology ensures a wide operating speed range of electric vehicles. It takes into account several physical and technological constraints. The model is highly parameterized and quickly helps to provide the dimensions and power train controlling parameters values by varying the mechanical characteristics of the vehicle. It is compatible with all brands of electric vehicle power with single motor. The analytical modeling approach is validated entirely by the finite element method.

Abstract: In this paper, we present a methodology for electrothermal characterization of two configurations: permanent magnet motor and its equivalent to wound rotor. This modeling approach is in the aim to evaluating the different temperatures in different active parts of the two configurations, to choose the type and characteristics of the cooling system to use. A comparative study between the two solutions is presented.

Abstract: In this paper, we present a systemic trapezoidal control methodology of a coiled rotor axial flux synchronous motor dedicated to electric traction, taking into account of several constraints such as the speed limit, the energy saving, the cost of the power chain and the reliability of the whole system. Indeed the control law developed allows to impose the electromotive forces in phase with the phase currents, which reduces vehicle consumption. Also based on the technique of overfluxing during periods of high acceleration to reduce the phase current of the motor and then the vehicle consumption. This optimization technique is based on the increase of the excitation current for a given torque, thereby increasing the electric motor constant. Therefore, the phase current is lowered leading to a reduction in consumption. During the phases of constant speed operation and high decelerations, the value of the excitation current is calculated iteratively to minimize the consummation. Finally, the results obtained are with good level which encourages the electronic integration phase of this control law.

Abstract: This paper describes the electric parameters determination for Synchronous Motor with Dual Excitation, using the joined method analytic/finite elements. Indeed several models of mutual and principal inductances and electric motor constant are developed analytically and validated by the finite elements method. These models are fortunately parameterized allowing to the formulation of several optimization problems such as the motor ripple torque.

Abstract: This paper describes the choice and the design of electric vehicles power train structure reducing considerably the energy consumption. Indeed The converter feeding the motor is naturally with IGBTs leading on the one hand to important losses and on the other hand to many control problems. This structure is replaced by another with electromagnetic switch leading to a strong reduction of the losses and to an increase of the electric motor control reliability. The power train contains an energy recuperation system during the deceleration phases, where the motor functions in generator. The motor is controlled by vector control method maintaining the current Id equal to zero, leading to the maintain of the current in phase with electromotive force, what also leads to the reduction of the energy consumption. A supper-capacity is added in parallel with the energy accumulator leads to an increase of the storage energy capacity. All these factors lead to the increase of the autonomy for a known stocked energy.

Abstract: In this paper, we present an analytic model of the whole motor converter taking in account of several systemic and physical constraints. Being couple to a model of the losses of the power chain and to a model of the mass of the motor, this analytic model puts a problem of conjoined optimization of the consumption and the cost of the motor. This problem is solved by genetic algorithms method.
