Increase of electromechanical devices as well as increased electrical energy demand on board, requires novel tools and methods to design and develop such devices, in a complex environment, like automobile is. In electrical engineering, the Finite Element Method (FEM) is a valid tool to examine the magnetic behaviour of these components in order to improve their performances. Moreover, in order to evaluate the impact of such components in their working conditions, a system simulation is often required. Time-stepping magnetic field computations are often used, but this approach requires heavy CPU (Central Processing Unit) loads. In this paper we present a different method in which a FEM code is used to evaluate circuit parameters of electrical devices and a circuit analysis tool is used to study the electrical system in real load conditions. The method is applied to a claw pole alternator and to an ignition coil and the validation with measures is presented.
