          Abstract

          Resumen: Se utiliza el núcleo del estator de una máquina eléctrica para aplicaciones docentes, con 12 dientes y ranuras abiertas, y se construye un rotor, de material magnético sinterizado, para configurar un alternador inductor heteropolar trifásico, con inversión de flujo. La optimización del diseño del rotor consiste en obtener el mejor número de dientes que proporcione una forma de onda de la tensión de salida más próxima a una función sinusoidal y con un mayor valor eficaz (rms). Se presenta un modelo analítico que permite establecer una comparación de los valores de las permeancias, según sea el número de dientes del rotor. Los resultados se contrastan con valores de simulación, utilizando un programa de elementos finitos. Se concluye que siete es el número idóneo de dientes y ranuras del rotor.

          Abstract: The stator core of an electric machine for teaching applications, with 12 teeth and open slots, is used and a rotor, of sintered magnetic material, is constructed to configure a flux switching three-phase heteropolar inductor alternator. The optimization of the rotor design consists of obtaining the best number of teeth that provides a waveform of the output voltage closest to a sinusoidal function and with a higher effective value (rms). An analytical model is presented, allowing to establish a comparison of the values of the permeances, depending on the number of teeth of the rotor. Results are compared with simulation values, using a finite element program. The conclusion reached is that seven is the ideal number of teeth and slots of the rotor.
