Comparaison de deux moteurs électriques autopilotés : le moteur synchrone à aimants permanents et le moteur à réluctance variable à double saillance

Dans cet article, nous effectuons une analyse paramétrique dimensionnelle du couple moyen et des pertes Joule dans le cas de deux moteurs autopilotés. Ces moteurs sont, d'une part, le moteur synchrone, à aimants montés en surface de type ferrite ou…

Performances Comparison of Permanent Magnet Brushless DC and Doubly Salient Reluctance Motors for an Urban Electric Vehicle

In this paper, we carried out a dimensional parametric analysis of average torque and copper losses in the case of two synchronous brushless motors. These motors were, on the one hand, a Permanent-Magnet Brushless DC (PMBLDC) motor supplied by quasi…

Current Feeding of Switched Reluctance Motor. Optimization of the Current Waveform to Minimize the Torque Ripple

The torque ripple remains one of the main problem linked to the use of switched reluctance motor. In order to use these drives in low speed application, we have imagined a current control, with optimized waveforms allowing torque ripple minimization…

Comparison of Electromagnetic Perturbations and Commutation Losses between Self-Switching and PWM Mode of Current Control in a Switched Reluctance Motor.

In a previous paper we have shown the interest of the bilifilar winding in SRM feed by low voltage (automotive application). The interest is the minimization of switche number and of silicon area. In this paper, we propose to continue the study of a…

Variable Reluctance Rotating Shaft Sensor for DC Brushless Vernier Reluctance Motor

In this paper, a variable Reluctance Rotating Shaft Sensor made with a stack of magnetic sheet a Switched Reluctance Motor is studied. The magnetic coupling are taken into eaccount and an 3D FE modelization is used. Synchronous demodulation is used…

Influence de l'entrefer sur les performances et le dimensionnement d'un moteur à réluctance variable à double saillance et de son onduleur

A switched reluctance motor drive has been chosen for mass production of a low cost application. This motor run in a speed rande from 1000 to 3000 rpm, the rated average torque is 0.1 N.m at maximum speed. A bifilar winding permit to reduce power…

Commande non linéaire en vitesse d'un servomoteur synchrone avec calcul de trajectoire et estimation du couple résistant

Dans cet article, une méthode est proposée pour améliorer robustesse et performances de la commande non linéaire du servomoteur synchrone. La méthode consiste à calculer en temps réel un trajectoire asymptotique pour la vitesse, engendrant un couple…

A robust total compensation algorithm for the torque control of a synchronous servomotor

In this paper, we present a performing torque controller for a synchronous servomotor. As we will see, this controller, called the total compensation controller, brings a new solution to the defects of the well known proportional integral controller…

Modelling complex systems via the analysis of qualitative data

Modelling problems are concerned with the relationships between input and output variables. When both sets of variables are qualitative ones, data analysis can be used to construct a model of the system expressed by a set of rules, on the basis of…

Learning a qualitative model of a complex system via data analysis

The contingency table of X and Y, is used to construct rules under the form : X=a ==> Y belongs to B(a). According to the nature of the data (ordered or not ordered), the simplification of these rules is performed, via the clustering of certain…
