Diseño de experimentos para modelar las faltas de mayor incidencia en el estator de los motores trifásicos de inducción.

Proyecto de Investigación. Instituto Tecnológico de Costa Rica. Vicerrectoría de Investigación y Extensión (VIE). Escuela de Ingeniería Electromecánica, 2012This paper's main objective is to design experiments to model higher incidence of faults in the stator of the three-phase induction motors, which are propose four experiments, the data obtained allow to know and evaluate effects on the internal temperature of the stator windings when the motor undergoes operation faults such as damaged roles, operated without a fan, voltages higher and lower than the nominal line voltage line and finally increments outside temperature close to 50 ° C. For the development of this project, the description of the background of presents problem solving, a description of the most important literary review related with the solution, the main achievements, conclusions and recommendations. Additionally the materials, equipment and procedure used is presented to construct the bed of the tests that achieve the goals in each experiment, and obtain sufficient data and subsequent analysis allows finding the mathematical model describing behavior to predict, in this case, the temperature internally in the stator windings when the electric motor operates fouls Finally the objectives, equipment, tools, diagrams, procedures are described, safety rules and other information that permits the four experiments proposed, but also data capture is achieved to facilitate orderly later analysis.Instituto Tecnológico de Costa Rica.
