Staged modelling A methodology for developing real-life electrical systems applied to the transient behaviour of a permanent magnet servo motor

This paper presents a methodology to achieve a global dynamic model of an electrical system that consists of a battery, an inverter, a permanent magnet servo motor and a turbine. The stress is placed on the fact that a classical finite element model would not be able to provide a satisfactory representation of the transient behaviour of the whole system. A staged modelling is proposed instead, which succeeds in providing a complete picture of the system and relies on numerous finite element computations.
