Abstract :
After presenting, based on Cherry rule, the classical deduction of the electric equivalent network of a transformer magnetic circuit, the authors introduce the extension of this topological approach when hysteresis losses are present. Specific considerations related to the matrix properties associated to the use of ideal transformers are also given. The method can be extended to the rotating machinery analysis. This allows to deduce the hysteresis torque
