The proposed numerical model is used to study the physics of inter-bar currents by investigating the three dimensional field solution. The long-term aim is to get a deeper and more accurate understanding of the physics to be able to further fine tune analytical theories about inter-bar currents. This work is used to verify the model and to get an idea of what can be achieved with it in the future...
An analytical model for the calculation of the steady-state behavior of an inverter-fed electrically excited synchronous motor is presented in this paper. The air-gap field is modulated with a magnetic permeance function. From this, position-dependent inductances can be derived. These inductances are used by the mathematical model of the machine that describes its dynamic behavior, when it is fed...
