1. IMPLEMENTAÇÃO DE TÉCNICAS DE CONTROLE DE MOTOR DE PASSO EM APLICAÇÕES CNC / IMPLEMENTATION OF CONTROL TECHNIQUES OF STEPPING MOTOR INTO CNC APPLICATIONS
O objetivo deste trabalho é desenvolver uma metodologia de controle de equipamentos acionados por motores de passo, via porta paralela de microcomputadores, com até três eixos programáveis, para utilização em processos de automação. Para implementar o sistema proposto, utilizou-se um ambiente de desenvolvimento de programas computacionais, através d

3. Contribuição ao estudo tribologico dos pares acionadores de motores ultra-sonicos
A tribological study of the potential materials to be employed in linear ultrasonic motors is presented. Different pairs of materiais such as steel/alumina, steel/diamond, alumina/diamond and diamond/diamond have been studied. The diamond samples were obtained by chemical vapor deposition (CVD) and used in the ultrasonic pairs without any previous polishing.

4. Fluctuation analysis of rotational speeds of the bacterial flagellar motor.
We measured the dependence of the variance in the rotation rate of tethered cells of Escherichia coli on the mean rotation rate over a regime in which the motor generates constant torque. This dependence was compared with that of broken motors. In either case, motor torque was augmented with externally applied torque. We show that, in contrast to broken moto
