“…Se introducirá también al par eléctrico un término de par resistente provocado por las pérdidas de potencia en el núcleo magnético. Estas pérdidas se consideran como la suma de las pérdidas por histéresis, pérdidas por corrientes de Eddy y pérdidas anómalas [5] [4]. Estasúltimas se suelen despreciar, resultando la potencia perdida como:…”

Este artículo trata el modelado de una planta de micro-generación destinada al abastecimiento eléctrico de regiones aisladas en países en vías de desarrollo. El objetivo del modelo es caracterizar fielmente el comportamiento de estas microcentrales ante acciones externas como la actuación sobre la válvula de admisión y la conexión o desconexión repentina de cargas. Este modelo permitirá el desarrollo de estrategias de control eficientes, robustas y sencillas, adaptadas al contexto de precariedad de este tipo de instalaciones.

“…The resulting values of flux density magnitude and frequency f (Hz) are used to calculate the iron loss qfe (W/m 3 ) in the tooth over the speed and current range using the Steinmetz formula (5), [8]. Values of flux density, and subsequently loss, in the back iron are scaled from the values predicted in the tooth.…”

Hybrid modules have been adopted by vehicle manufacturers to create hybrid variants of existing models. This paper presents the potential performance of an axial flux permanent magnet machine against typical hybrid module design requirements. A multi physics analytical model is implemented and validated experimentally. This is followed by a parametric design study showing that the axial flux topology provides its maximum specific torques and powers within the available package space. Based on the hybrid module design requirements a design is identified for further development and its performance is confirmed through 3D finite element analysis. It is found that in a package space of 300mm diameter and 90mm length (including casings and water jacket) the axial flux topology offers 390Nm and 98kW for lOs, and 159Nm and 66kW continuously. Future work will include full mechanical design and prototyping of the concept.

“…The eddy current losses can be written as reported in (2). In (1) and (2) "a" and "b" are material parameters depending on the flux density and frequency, as shown in [24], [25]. In order to simplify the computational approach in the proposed method "a" and "b" are kept constant.…”

In this paper an easy method for the iron loss prediction in PWM inverter fed induction motors is presented. The method was initially proposed and validated for the prediction of the iron losses in non-oriented soft magnetic material with PWM supply. Starting from the iron losses measured with sinusoidal supply and the PWM waveform characteristics, a fast and reliable prediction of the iron losses in the motor can be obtained too. The method requires the separation of the iron losses in the hysteresis and eddy current components with sinusoidal supply, plus the average rectified and RMS values of the applied PWM voltage. The proposed method has been proved on an induction motor prototype able to provide a good accuracy in the iron losses measurement. The comparison between the measured and predicted iron losses with PWM supply have shown an excellent agreement with an error lower then the 5%, confirming the method validity.
