The model of asynchronous induction machines

Proceedings. International Conference on Power System Technology, 2003
A new method to obtain the new model of asynchronous machines is presented in the article. The new model can be used when the parameters of the machine's stator are unbalance. The simulation and experiment results show that in the scope suited to Park model, the new model has the exactly same behavior as the Park model. When there are unbalanced stator

Dynamic model of asynchronous machine

2017 18th International Scientific Conference on Electric Power Engineering (EPE), 2017
This paper deals the mathematical description of an asynchronous machine. Differential equations are then used to create a dynamic model of asynchronous machine. For the possibility of evaluation the quality of the created model are created at the conclusion the basic characteristics of representing the asynchronous machine.

Emptiness Is Decidable for Asynchronous Cellular Machines

2000
We resume the investigation of asynchronous cellular automata. Originally, these devices were considered in the context of Mazurkiewicz traces, and later generalized to run on arbitrary pomsets without autoconcurrency by Droste and Gastin [3]. While the universality of the accepted language is known to be undecidable [11], we show here that the ...

Handbook of Asynchronous Machine with Variable Speed

2013
This handbook deals with the asynchronous machine in its close environment. It was born from a reflection on this electromagnetic converter whose integration in industrial environments takes a wide part. Previously this type of motor operated at fixed speed, from now on it has been integrated more and more in processes at variable speed.

Simulation of an asynchronized synchronous machine

Mathematics and Computers in Simulation, 1973
This paper describes a detailed analogue computer simulation of an asynchronized synchronous machine, which is suitable for investigating both steady-state and transient performance. A simple method is presented for simulating asynchronous operating conditions, and developed to provide the required excitation control.

Machine asynchrone

1995
Le contrôle de toute machine est basé sur un modèle caractérisé par un ensemble de paramètres. Dans ce travail on propose et on compare différentes méthodes d'identification des modèles de la machine asynchrone. Le problème principal consiste à choisir un modèle et à en identifier les paramètres pour traduire au mieux les comportements de la machine ...

Machines asynchrones - Régimes quelconques

Conversion de l'énergie électrique, 2000
Les developpements mathematiques de l’article « Machines asynchrones. Regime permanent » ne sont naturellement pas valables si les tensions d’alimentation ne sont pas sinusoidales permanentes et/ou si la vitesse n’est pas constante. Nous allons donc les reprendre en levant ces deux restrictions.

Machines asynchrones - Régime permanent

Conversion de l'énergie électrique, 1998
Plus de la moitie de l’energie electrique produite dans les pays industrialises est transformee en energie mecanique, par des moteurs. La plupart de ceux-ci appartiennent a l’un des types suivants : a courant continu, asynchrone, synchrone, a courant alternatif a collecteur.

Fault detection experiments for asynchronous sequential machines

11th Annual Symposium on Switching and Automata Theory (swat 1970), 1970
A new flow table for describing normal-fundamental-mode (NFM) asynchronous machines, the ADSE table, is introduced. Although the structure of this table has several ramifications in the area of circuit realization, this paper emphasizes its utility in generating checking experiments for NFM asynchronous machines.
