La prueba electrica que se hace a motores electricos para medir su velocidad, corriente y Torque se ha realizado historicamente mediante el uso de Dynamometros, este libro propone un metodo alternativo para realizar la prueba a los motores electricos por medio de la inercia de la armadura (ILT) y usando como unico elemento sensitivo un sensor de corriente del tipo shunt. Por medio de la medicion de la corriente se caracteriza en velocidad, corriente y Torque al motor bajo prueba en menos de dos segundos, calculando su Torque y midiendo su velocidad por medio de los pulsos de conmutacion. Las...

This edited volume explores the multifaceted nature of teacher emotions, presenting current research from different approaches and perspectives, focused towards the second language classroom.

These days, numerous studies document and advocate the potential effectiveness of the CLIL approach, which is viewed as a real revolution in second language pedagogy.
