An Approach for the BH Curve Identification of Magnetic Core of Synchronous Reluctance Machines

A method for BH curve identification of the magnetic core synchronous reluctance machines is presented. It starts from knowledge machine torque or phase voltages measured at normal operation with ac balanced currents obtained dedicated experiments proposed identification. The formulated as an inverse optimization problem where experimental data based on appropriate serve inputs and parameters represented a closed-form expression variables. influence different types measurements identified process discussed compared. Moreover, impact geometrical uncertainties due to manufacturing tolerances investigated addressed. Virtual finite-element simulations are used study. shown that can identify good accuracy.
