Onduleur MLI pour servomoteur synchrone: minimisation des pulsations de couple

Les auteurs analysent l'origine des puisations de couple à basse fréquence observées pour des servomoteurs alimentés par un onduleur MLI. Ils en déduisent une méthode de minimisation de ces pulsations et indiquent les résultats obtenus

Low Cost Flux Switching Linear Hybrid Actuator

It's now possible to better satisfy the need for direct linear actuators. In particular, the household applications represent an expanding market. The principal constraints are the cost and the noise. We propose, in this paper, a new electromagnetic…

Influence of Stator Yoke Thickness and Stator Teeth Shape upon Ripple and Average Torque of Switched Reluctance Motors

During the investigation of the Switched Reluctance Motor (SRM), we became interested in two apparently secondary parameters which are: - the thickness of the stator yoke; - the shape of stator teeth. In keeping the other geometrical parameters,…

A New Indirect Rotor Position Sensing with Resonant Method for Switched Reluctance Motor

The paper describes an original method based on the principle of inductance measurement in the unenergized phase. A serie resonant circuit is used with the phase inductance carying with the position. The capacitor value is dertimend for resonance…

Étude des perturbations conduites et rayonnées dans une cellule de commutation

The principles used in static conversion and the rise of the performances of the new switching devices contribue to increase the level of electromagnetic noises emitted by electronic converters. We have studied the way how these perturbations are…

COMPARISON OF SPEED NONLINEAR CONTROL STRATEGIES FOR THE SYNCHRONOUS SERVOMOTOR

ABSTRACT In this paper, several strategies to improve robustness and performances of speed nonlinear control of the synchronous servomotor are proposed and compared. The followed procedure consists in imposing the maximum acceptable motor torque…

Pole Arcs Optimization of Vernier Reluctance Motors Supplied with Square Wave Current

To maximize their performances, it is profitable to supply vernier reluctance motors (VRMs or Switched Reluctance Motors) with square wave current, but the converter has to switch this current successively into each inductive phase. This raises…

Sensorless Rotor Position Analysis using Resonant Method for Switched Reluctance Motor

Discrete position sensors are undesirable in our automotive applications. We are looking for a sensitive,simple, robust and low cost sensing method for the positioning of a rotor in a doubly salient motor. This paper describes an experimental…

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…
