Medium rating PM machines equipped with concentrated armature windings are becoming more and more popular, for their good constructional and operation features. The unusual structure of these machines makes their modelling and design quite special, both concerning the electromagnetic aspects and as regards their thermal questions. This paper analyses some cooling elements and thermal modelling of cylindrical air-gap PM machines, with particular attention to the following elements: cooling circuit, losses computation, thermal network definition, temperature calculation of the thermally vulnerable parts, temperature dependence of the machine performances.

Abstract
Medium rating PM machines equipped with concentrated armature windings are becoming more and more popular, for their good constructional and operation features. The unusual structure of these machines makes their modelling and design quite special, both concerning the electromagnetic aspects and as regards their thermal questions. This paper analyses some cooling elements and thermal modelling of cylindrical air-gap PM machines, with particular attention to the following elements: cooling circuit, losses computation, thermal network definition, temperature calculation of the thermally vulnerable parts, temperature dependence of the machine performances.| File | Dimensione | Formato | |
