Abstract The compensation ferrometer is an instrument for the measurement of open specimen soft magnetic materials parameters at AC magnetization based on the magnetomotive force compensation method. New magnetizing process regulator that controls voltage induced in measuring winding (magnetic flux density waveform) and the voltage induced across Rogowski-Chattock potentiometer (compensation) was developed recently. This paper deals with a new compensation ferrometer design that allows taking the full advantage of the new regulator. New ferrometer based on STEMlab platform improves precision and speed of the measurement.

Energetic Characterization

In recent years, innovative magnetic materials have been introduced in the field of electrical machines. In the ambit of soft magnetic materials, laminated steels guarantee good robustness and high magnetic performance but, in some high-frequency applications, can be replaced by Soft Magnetic Composite (SMC) materials. SMC materials allow us to reduce the eddy currents and to design innovative 3D magnetic circuits. In general, SMCs are characterized at room temperature, but as electrical machines operate at high temperature (around 100 °C), an investigation analysis of the temperature effect has been carried out on these materials; in particular, three SMC samples with different binder percentages and process parameters have been considered for magnetic and energetic characterization.
