1. Thermodynamics of electromechanical systems

1.1 Postulates and working hypotheses

The thermodynamic point of view provides a powerful and generic basis for formalizing the problem of electromechanical energy conversion. Thus, in accordance with the diagram shown in figure 1 , the converters studied will be considered, in general terms, as closed systems capable of transferring energy between electrical and mechanical generators and receivers, by exploiting one or more electro-magnetic-mechanical interaction phenomena. In the context of classical thermodynamics, such a system is characterized by a set of macro-scopic parameters (of scalar, vector or tensor nature), among which we can distinguish external parameters,...
