The low frequency electromagnetic emission from permanent magnet synchronous motors is studied. The main objective is to provide safety regions for humans in the vicinity of these motors, especially that, these motors are now being used widely in humans' existence areas, where high flux densities are expected. In this study, a new equivalent magnetic circuit is proposed to estimate the stray fields...
Prediction of hybrid stepping motor performance is made possible using an analytical model based on the motor's equivalent magnetic circuit. The motor's static torque behaviour can be determined by drawing the energy balance of the magnetic circuit. Circuit elements consist of magnetomotive forces induced by the permanent magnet and the stator's windings as well as permeances for iron parts and air...
Due to their simplicity, robustness, high performances and reduced cost, the variable reluctance machines (VRM) occupy today a place of choice in the electromechanical conversion of energy. Hence the growing interest for the study and the design of a new structures more successful and better adapted to the new requirements. The purpose of this paper is to propose a useful and comprehensive design...
