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.
