Abstract

This article explores the impact of belt looseness on electrical and mechanical quantities of a system driven by an induction motor and a belt-pulley transmission. The effects of this defect, for example the belt slipping or the apparition of spectral signatures in some measurements, are first investigated under steady state operation. Transient state tests are then performed to analyse, in the time domain, the system response to a step of the speed reference. The behaviour of different variables (slip,speed, currents, etc.) is studied for different health conditions and the increase of the belt looseness clearly impact the electric and mechanical variables’ waveforms. The experimental tests carried out in this study, under steady or transient state, show promising results for the diagnosis of belt degradations. Perspectives of this work are therefore detailed at the end of this paper.

Abstract

The different voltage waveforms along with their distribution in the inverter fed motor windings are presented with the help of a specially equipped machine. As a matter of fact, even though a lot has been said on the possible premature failure of such machines, little is known on the internal voltages appearing in the windings or for that matter from a theoretical point of view, the reasons for such voltage distributions. The aim of this paper is to demonstrate that for more accurate picture emerges by taking into account the energy losses in the iron frame. The use of a new mathematical tool called 'diffusive representation' permits to obtain a simple model for time-domain simulations. Such an approach gives very good results as demonstrated in the paper. Index Terms--AC motor, dv/dt, PWM drives, transient effects, voltage stress.

Abstract

International audience; This paper develops a method for analyzing the constant speed steady state of a three phase excited synchronous machine fed with any periodic voltages. The dq Harmonic Balance method is extended to account for back emf – linkage flux – and its time harmonics in current and torque waveform determinations. The method is applied to the case of surface mounted permanent magnet machines and to the case of interior permanent magnet machines with circumferentially magnetized magnets. Comparisons of current and torque waveforms obtained by time resolutions, finite element computations, and experimental measurements are performed and are favorable when the magnetic material linear hypothesis is verified. Moreover, the method is low computation time consuming and so it is suitable for rapid analysis of machines and for iterative optimal design procedures.

Abstract

International audience; Les applications nécessitant des entrainements électriques à haute vitesse impliquent des contraintes de dimensionnement inhabituelles tant au niveau de la machine que de son alimentation. L'approche système conduit à considérer l'ensemble {Onduleur+Machine} et les relations internes entre sous-systèmes dès la phase de conception. Une optimisation de la performance énergétique du système, sur la base de modèles analytiques multi-domaines, multi-physiques, du premier ordre, est menée pour diverses structures d'onduleur. La dépendance de la géométrie des machines optimales – au sens de l'optimalité globale du système – à la topologie de l'alimentation est clairement établie et une structure optimale de système mécatronique répondant au cahier des charges posé est dégagée.
