  • Abstract
    Assuming knowledge of the flux density distribution due to field and armature windings in the air gap of a large synchronous machine, it is possible to calculate the impact that inter-bar resistance and skew have on the amortisseur winding currents. A theoretical approach to predict amortisseur currents is developed and then the effect on open circuit voltage harmonics is investigated. Developing theory to predict the losses in the core of the machine, the impact of skew and inter-bar resistance on the predicted core loss is also investigated.
