| Resumo: |
Rotating electric machine tests are essential to determine the actual performance, power factor, machine torque, heating regime and its dynamic behavior. Belt mechanical dynamometers are usually used to perform this test, where the electrical characteristics and their working curve are determined. This work has the purpose of presenting, based on the bibliographies and works already done, a brake by Foucault's parasite currents, which uses the concept of circulating currents inside conductive materials that are under the action of constant magnetic fields. Usually treated as a heating source in electric machines and, consequently, losses of its efficiency, the concept of the parasite currents has been used, so that, by means of an electromechanical
device, torque can be applied to the axis of rotating electric machines, thus simulating mechanical loads and making electrical tests possible. Eddy current brake has been constructed and tested to provide reliable, robust and easy-to-use equipment for motor starters up to 2 Hp, designed through information collected from libraries and previously run and researched work. |
