...Prof. Norio Takahashi; Zhao Haisen; Liu Xiaofang; Cui Xueshen; Luo Yingli Purpose – The purpose of the paper is to study the influence of rotational flux on local core losses of the motors, which is difficult to distinguish the iron losses caused by rotational flux in certain electric machines...

...A. Tenhunen; T.P. Holopainen; A. Arkkio There is an unbalanced magnetic pull between the rotor and stator of the cage induction motor when the rotor is not concentric with the stator. These forces depend on the position and motion of the centre point of the rotor. In this paper, the linearity...

...Lieven Vandevelde; Johan J.C. Gyselinck; Francis Bokose; Jan A.A. Melkebeek Vibrations and acoustic noise are some of the fundamental problems in the design and exploitation of switched reluctance motors (SRMs). Adequate experimental and analysis methods may help to resolve these problems...

...S. Poullain; J.L. Thomas; A. Benchaib This paper proposes a new discrete‐time formulation of state‐space model for voltage source inverter (VSI) fed AC motors, introducing the free evolution of the motor state and characterized by both the simplification of torque and flux output equations...

...Irma Hajdarevic; Hansjörg Köfler Switched reluctance motors are promising candidates for a wide variety of drive applications. The theoretical description of such motors is often reduced to the rather simple, but clear concept of ΨI‐characteristics. In contrast to this, the machine itself is a real...

...R. Felicetti; I. Ramesohl This paper describes a thermal and electrical model, used at Robert Bosch GmbH for the design of an innovative motor for a water‐pump. In addition, it offers an example of a highly integrated mechatronic system. A bonded‐ferrite inner rotor has been developed...

...M. Kaiserseder; J. Schmid; W. Amrhein; V. Scheef A torque ripple minimization technique for switched reluctance motors is shown in this paper. Precalculated current shapes are applied to reduce torque ripple and to raise the degrees of freedom of the application in the commutation region...

...Marian Lukaniszyn; Mariusz Jagiela; Rafal Wrobel A brushless, permanent magnet, three‐phase disc‐type salient‐pole DC motor with co‐axial flux in the stator is considered. Electromechanical properties of a basic eight‐pole motor are compared with those for a 16‐pole one of the same volume, in order...

...Marian Lukaniszyn; Rafal Wrobe; Mariusz Jagiela This paper presents the field‐circuit analysis of a disc‐type torus DC motor with permanent magnets. Calculations of the magnetic field are carried out using the finite element method (FEM) in the 3D space. The integral quantities like the ripple...

...K. Wiak Discusses the 27 papers in ISEF 1999 Proceedings on the subject of electromagnetisms. States the groups of papers cover such subjects within the discipline as: induction machines; reluctance motors; PM motors; transformers and reactors; and special problems and applications. Debates all...
