To ensure reliable drive with an induction machine requires deep insight in electro-mechanical dynamics during its operation. The flexible multibody modeling technique enables the simulation of dynamic loads on all drive components. This paper focuses on complex modeling of machine's behavior in case of eccentrically placed rotor. The life time of machine's bearing becomes very important issue of...
This paper deeply discusses the effect of eccentricity, including static, dynamic and mixed eccentricity on the performance of FSCW SPM servo motor analytically and using finite element analysis (FEA) to validation. The effect of different kinds of eccentricity on magnetic field including magnet field and armature reaction field is described with three factor called modulation factor. The frequency...
We report an investigation of saturation effects on the unbalanced magnetic pull in a hydroelectric generator with 20% static eccentricity. We determine the magnetic pull force by the finite-element method in parallel with a simple analytical model for various no-load voltages and loads. Saturation significantly affects the magnitude of the unbalanced magnetic pull for high voltages and large loads.
