Electromagnetic Calculation of an Inductor Generator with a Unipolar Field Winding on the Stator
The magnetic field created in an inductor generator equipped with a unipolar field winding placed in the central zone between the stator core stacks has a complicated 3D pattern. Although modern computer programs based on the finite-element method make it possible to calculate this 3D field, they require considerable computational resources. A method for calculating the magnetic circuit is proposed that allows a 2D finite-element method to be applied, thereby reducing considerably the computation time, while preserving the possibility of taking the saturation of steel into account
