Desenvolvimento de uma bancada para ensaio de máquinas elétricas contendo um freio por correntes de Foucault

Abstract

This work describes the process of developing a test bench for an eddy current brake, which had a prototype previously built in another work. Although the prototype worked as expected, the need arose to measure the torque developed by the brake without having to know the engine parameters. Then, an alternative was sought, based on the operation of a dynamometer, to make it possible to measure the conjugate generated by it. However, due to the dubious mechanical strength of the structure and vibration problems in the workbench, the need arose to design a new workbench, this time performing a prior analysis using finite element software to preventing it from experiencing resonance problems which, in addition to causing interference with measurements, can lead to hostile operating situations from a vibration standpoint.
