...Leysmir Adriana Millan Mirabal; Oualid Messal; Abdelkader Benabou; Yvonnick Le Menach; Loic Chevallier; Jean-Yves Roger; Jean-Pierre Ducreux Purpose The purpose of this study is to explore the effect of the demagnetizing field in the Epstein characterization of grain-oriented electrical steels...

...Farshid Mahmouditabar; Abolfazl Vahedi; Pourya Ojaghlu; Noureddine Takorabet Purpose This paper aims to present a modified MEC algorithm for demagnetization modeling of the PM motor. One of the major issues that the designers of the permanent magnet (PM) motors are faced...

.../methodology/approach A novel rotor structure with rectangular PMs is discussed with respect to the demagnetization of ferrite magnets and mechanical strength. Some electromagnetic characteristics including torque, output power, loss and efficiency are calculated by 2D finite element analysis. Findings...

.../methodology/approach – Based on 2D finite element analysis (FEA), the thermal performances, such as temperature distribution, the optimization of water flow rate and the influence of demagnetization, are investigated under the condition of continuous duty. Then the maximum current density and average thrust...

... It has been found that the introduced DTC strategy offers higher performance than the Takahashi one. Of particular interest are: the reduction of both torque ripple and commutation frequency; the eradication of the demagnetization problem which is a vital requirement in position control applications...
