A synchronous axial flux PM machine d,q axes model which takes into account iron losses, saturation and temperature effects on the windings and the permanent magnets

Abstract

Electrical machine models in which non linear and other second order effects of various nature aren't considered have a limited validity and scope. Adherence to actual machine behaviour is of utmost importance when such models are used to improve design predictions or when they are used in sensitive control applications, such as sensorless control. This paper proposes an evaluation criterion of the most important of these effects in AFPMs and a machine model that takes them into account in order to obtain a better faithfulness to actual machine operation
