This contribution introduces a vector interpretation to unify the description of torque development in rotating electrical machines. The motivation behind this attempt is necessity applying different physical and calculation methods, such as Lorentz force, Maxwell stress tensor, co-energy methods etc., for predicting estimating components, e.g. synchronous torque, oscillating cogging reluctance...

Network based conductivity reconstruction method is introduced using the third Maxwell’s equation, or Faraday’s law, for a static case. The usual choice in electrical impedance tomography is the divergence free equation of the electrical current density. However, if the electrical current density is given, the curl free equation of the electrical field gives a direct relation between the curren...

In order to develop a software that aims at helping reducing the electrical energy consumption in the domestic sector of the European Union, it becomes necessary to model the electrical energy consumption of the main home appliances as a function of their features such as energy class, capacity and operating set-ups. This paper focuses on the modeling of electrical energy consumption of the was...

The ever-increasing demand for higher-power dense electrical machines has resulted in different electrical, mechanical, and thermal stresses, which can eventually cause machine failure. For this reason, the management of stresses losses must be thoughtfully investigated to have a highly reliable machine. literature agrees that winding are dominant loss mechanism many machines. However, statemen...

Performing fast and accurate methods for modeling the electrical machines has been the subject of several studies and many authors proposed different procedures to attain this aim. Beside the accuracy, the speed of the method is of great concern. On the other hand, the capability of the method to be changed according to the need is another important issue. Finite Element method provides relativ...
