Dissertação (Mestrado em Engenharia Elétrica e da Computação) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/6611The Permanent Magnet Brushless DC Machine has been used increasingly in numerous applications, such as in industry, transportation systems and wind energy conversion. Given this scenario and the need for knowledge of machine parameters for design purposes, performance analysis and operation of systems, this paper aims to present methodologies and the development of a test system. The test system is based on virtual instrumentation and aims to determine phase resistance, inductances, viscous and static friction coefficients, inertia, and electromotive force and torque constants. In many aspects, the test system is a tool that fills a gap in the area. To check the validity of the obtained parameters and to study machine's perfomance, computer simulations and load tests are performed.application/pdfAcesso AbertoInstrumentação virtualMáquinas elétricasÍmã permanenteBrushless DC MotorENGENHARIA ELETRICA::MATERIAIS ELETRICOSDissertação
