The phenomenological model, examined in this paper, uses mechanically supported magnetic dipoles, which are arranged to a collective on a regular Cartesian grid. In a former work, the authors showed, that the model is capable to re-enact the basic dynamics of a measured hysteresis after a parameter optimization process. One of the main issues of the parameter optimization process is the mechanical...
In this paper, a phenomenological 3D hysteresis model using magnetic dipoles, which are mechanically supported on a 3-dimensional grid, is investigated. The different interactions between these dipoles are based on the equations of micromagnetism. Instead of minimizing the free energy in the system by mathematical optimization methods, each elementary dipole is able to rotate into an individual energetically...
This paper presents the design and implementation of a high speed sensorless brushless DC motor (BLDCM) drive with commutation compensation. The back electromotive force (EMF) detection using three phase terminal voltage is implemented to detect the rotor position, in order to filter the high frequency switching signals, a low pass filter is applied in the back EMF detection circuits, the cut-off...
