... in the characteristic equations. The analysis takes the salient pole synchronous machine as a general case of study. Then the approaches are extended to undamped and smooth air gap synchronous machines as well as induction machines. The paper aims to discuss these issues. Design/methodology/approach – The present...

...Slawomir Wiak; Bernhard Weilharter; Oszkár Bíró; Siegfried Rainer Purpose The purpose of this paper is to analyse the surface vibrations of an induction machine due to force waves acting on the stator and rotor core. The focus lies on the investigation of the influence of force waves with axial...

...Andrzej Demenko; Dorota Stachowiak The equivalent fixed grid and moving grid models for the finite element (FE) analysis of an induction machine are presented. The discussed transformation is the FE representation of the classical commutator transformation. The obtained fixed grid model takes...

...C. Delmotte‐Delforge; H. Hénao; G. Ekwe; P. Brochet; G‐A. Capolino This paper presents two modeling methods applied to induction machine study in order to construct a tool for diagnosis purpose. The first method is based on permeance networks using finite element analysis to calculate magnetic...

...Jan Rusek Based on Fourier series theory, for almost periodic functions, the general as well as the specific harmonic‐balance model of induction machines is presented together with a brief derivation. Whereas the general model refers to both symmetrical and asymmetrical machines, the specific one...

...Aldo Canova; Marco Ottella; Roger John Hill‐Cottingham Presents the use of a 3D eddy current FE procedure for the analysis and design of two different induction machine structures: a radial and an axial machine. In the first case, attention is devoted to the simulation of locked rotor conditions...

... an experimental device using cut iron sheets of the machine. The second section deals with validating the model by using it to study an induction machine in motor running. The no load and locked rotor tests are simulated and the calculated results are compared to the experimental ones. Likewise, the results...

... element method Induction machines Electromagnetics Motion The classical theory of a balanced three phase induction machine is based on the assumption that the magnetic field has only the rotating component. However, in reality the pulsating field also exists. The saturation harmonics create...
