1. An analysis on electric and magnetic behaviour on an induction planar actuator
The induction planar actuator, i.e. IPA, proposed in this study presents an electromagnetic structure formed by a static ferromagnetic core with an aluminium plate that corresponds to the secondary, and a mover, also called primary. The latter comprehends two three-phase windings, mounted in an armature core, which are orthogonal to each other. When they are

2. Application of neodymuim-iron-boron permanent magnets on the assembling of a novel planar actuator
This paper depicts a new planar actuator, with novel structure and construction features. It includes a slotless stationary plane armature and a mover with two permanent magnets. By using NdFeB permanent magnets with high-energy product, it became possible to develop a planar motor with a novel topology. The planar actuator develops movement over a plane sur

3. Analytical method to predict the static performance of a planar actuator
An analytical method for predicting the three-dimensional (3-D) magnetic flux density distribution in the air gap produced by permanent magnets of an electromagnetic planar actuator, was developed. The analytical 3-D model was validated by means of a finite-element model and by measurements. It allowed the understanding of the behavior of the flux density in

4. Evaluation of the normal force of a planar actuator
This paper describes a method to compute the normal force that acts on the mover of an electromagnetic planar actuator. The method is based on the Maxwell Stress Tensor and depends on the resulting magnetic field. The actuator has a mover with two permanent magnets and a ferromagnetic stator covered by two orthogonal armature coils. The mover is hold by a su

5. Estudo e desenvolvimento de um atuador planar com enrolamentos planificados e núcleo de material ferromagnético compósito
O presente trabalho trata do estudo, análise, construção e teste de uma nova configuração para um atuador planar. O dispositivo é composto de um núcleo de armadura ferromagnético plano, estático e sem ranhuras sobre o qual são montados dois conjuntos de enrolamentos planares, ortogonais entre si, com quatro bobinas cada, eletricamente independentes

6. Projeto de atuadores piezelétricos flextensionais usando o método de otimização topológica. / Design of flextensional piezoelectric actuator using the topology optimization method.
Flextensional Piezoelectric Actuators consist of a flexible structure actuated by piezoelectric ceramics (or a stack of piezoceramics). The flexible structure connected to the piezoceramic must generate displacements and forces in different specified points of the domain, according to a specific direction. These actuators are applied to precision mechanic ap
