Résumé

This paper presents a method to analytically model the self and mutual phase inductances of a brushless dc motor with a Faulhaber winding. The method of images is used to “remove” the motor iron parts in the model in order to analyze the winding completely in the air. The analytical model is verified using 3-D finite-element method simulations and measurements.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings.

Moteur sans balais

Un moteur sans balais, ou « moteur brushless », ou machine synchrone auto-pilotée à aimants permanents, est une machine électrique de la catégorie des machines synchrones, dont le rotor est constitué d'un ou de plusieurs aimants permanents et pourvu d'origine d'un capteur de position rotorique : capteur à effet Hall, synchro-résolver, codeur rotatif (par exemple codeur incrémental), ou tout autre système permettant l'auto-pilotage de la machine. Vu de l'extérieur, il fonctionne en courant continu.

A Reduced Order Model for Domain Decompositions with Non-conforming Interfaces

Alfio Quarteroni, Andrea Manzoni

In this paper, we propose a reduced-order modeling strategy for two-way Dirichlet-Neumann parametric coupled problems solved with domain-decomposition (DD) sub-structuring methods. We split the original coupled differential problem into two sub-problems wi ...

Pseudo-Three-Dimensional Analytical Model of Linear Induction Motors for High-Speed Applications

Mario Paolone, André Hodder, Lucien André Félicien Pierrejean, Simone Rametti

Literature on linear induction motors (LIMs) has proposed several approaches to model the behavior of such devices for different applications. In terms of accuracy and fidelity, field analysis-based models are the most relevant. Closed-form or numerical so ...
