Abridgment of additional losses of synchronous machines

Thermographic Measurement and Simulation of Power Losses Due to Interlaminar Contacts in Electrical Sheets

“…In this paper, the loss density due to the galvanic contacts and the It is well known that if a step function of heat generation is applied to a medium under steady state conditions, the instantaneous initial rate of rising of temperature at any point is directly proportional to the heat generated at the point [9]. Based on this principle, the thermal method has been exploited to obtain the core loss of electrical machines [10], [11]. It has been shown in [9] that sufficient accuracy can be obtained if measurements are made over a short period.…”
