This paper presents a new scheme for parallel hybrid power filter with variable passive part. The proposed model uses a current variable inductor in passive part designed by the software of finite elements method (FEM). The aim of this scheme is reducing power rating of active part of hybrid power filter. To evaluate its performance, this method is simulated by using MATLAB Simulink power system toolbox...
Switched reluctance motors (SRM) is gaining wider popularity for variable speed drives. These motors have been developed for electric propulsion, fan, pump and even as starter/alternator for aerospace applications. This paper gives the step-by-step design procedure of a 16/12 switched reluctance motor for a spacecraft actuator. Machine design has been started with analytical method to fix the major...
In the recent designs of electrical rotating machines, the emphasis are to have high capacity and electrical loading without comparable increase in size. Therefore the end-winding support structure becomes more significant to withstand with large stress developed due to electromagnetic forces. The end winding support structure of large rotating machine is designed to ensure that the stress in copper...
In this paper, the performance analyses of the three phase induction motors have been done by finite element method (FEM) using time harmonic and transient with motion solvers. If there is no saturation in the ferrous portion of the mutual-flux path, the flux wave in the motor approaches a sine-wave shape, but some amount of saturation always exists in a typical three phase induction motor that has...
During the past few decades, the numerical computation of magnetic fields has gradually become a standard in electrical machine design. Finite element method (FEM) has the advantage over previous design calculation procedures in that geometric variations and irregularities, saturation and eddy current effects can be modeled with a high degree of accuracy. Besides these advantages, the method does...
