I28-R145-131_oai2026-02-11 Veyrat Durbex, Alejandro Fabio Nachajon Schwartz, Yaki Tacca, Hernán 2021-06-15 The continuous search for improvement in electromechanical developments requires a clear understanding of the torque measurement required in each application. The decisions made will have a profound impact on the quality and cost of the results. This article presents the principles normally used for sensing mechanical torque on a shaft and the reasons for the widespread use of strain gauges. The importance of differentiation between static and dynamic measurements and the current technologies used in each case are discussed. The relevant factors that define a transducer are described and a comparative analysis between them is carried out, to then examine the possible mounting methods, with their benefits and limitations. Finally, different low-cost solutions are proposed for the design of the torque and speed measurement section without sacrificing system performance, for different test benches for electrical machine controllers, including the necessary signal conditioning electronics. The article aims to be a tutorial compendium of topics to study to successfully implement a test bench without damaging the torque transducer or introducing measurement errors, since the information on these topics is scattered and it is difficult to access knowledge of the selection criteria and project procedures. La continua búsqueda de la mejora en los desarrollos electromecánicos impone una clara comprensión de la medición de par necesaria en cada aplicación. Las decisiones tomadas tendrán un profundo impacto en la calidad y el costo de los resultados. En este artículo se presentan los principios comúnmente empleados para el sensado de par mecánico en un eje y el porqué de la utilización extendida de las galgas extensiométricas. Se discuten la importancia en la diferenciación entre las mediciones estáticas y dinámicas, y las tecnologías actuales utilizadas en cada caso. Se describen los factores relevantes que definen a un transductor y se realiza un análisis comparativo entre ellos, para luego examinar los posibles métodos de montaje, con sus beneficios y limitaciones. Finalmente se proponen distintas soluciones de bajo costo para el diseño de la sección de medición de par y velocidad sin sacrificar el rendimiento del sistema, para diferentes bancos de ensayos para controladores de máquinas eléctricas, incluyendo la electrónica de acondicionamiento de señal necesaria. El articulo pretende ser un compendio tutorial de temas a estudiar para implementar con éxito un banco de ensayos sin dañar al transductor de par ni introducir errores de medición, ya que la información sobre esos temas está dispersa y es difícil acceder al conocimiento de los criterios de selección y procedimientos de proyecto. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/131 10.37537/rev.elektron.5.1.131.2021 eng FIUBA https://elektron.fi.uba.ar/elektron/article/view/131/242 https://elektron.fi.uba.ar/elektron/article/view/131/243 Derechos de autor 2021 Alejandro Fabio Veyrat Durbex Elektron Journal; Vol. 5 No. 1 (2021); 20-31 Revista Elektron; Vol. 5 Núm. 1 (2021); 20-31 Revista Elektron; v. 5 n. 1 (2021); 20-31 2525-0159 2525-0159 Electric machines torque transducer torque measurement Máquinas eléctricas transductor de par medición de par Solutions for Torque and Speed Measurement on Electric Machine Controllers Test Benches Soluciones para la medición de par y velocidad en bancos de ensayos de controladores de máquinas eléctricas info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=131_oai |
