Abstract
This paper presents a comprehensive computational
fluid dynamics (CFD) model of a radial flux permanent magnet
synchronous machine with interior magnets. In the CFD model,
the water jacket cooling and a simplified model of the topology
of the distributed stator winding are considered. The heat sources
of the CFD model are determined from a finite-element analysis of
the machine. The numerically determined temperature distributions
of the machine are compared with measurement results from
sensors located both in the stator and rotor. The particular focus
of this paper is the analysis of the temperatures and the heat flow
in the air gap and from the stator winding heads and the rotor to
the inner air. Different operating conditions and two particular
rotor designs with different inner air flow configurations are
investigated. The potential of improving the thermal utilization of
a rotor design with fan blades attached to the mounting plates of
the rotor is shown.
