Abstract
In this paper an innovative thermal model for
the determination of the temperatures of the permanent
magnets and stator windings is presented. This model relies
on one temperature sensor located in the stator core of
the machine. The estimated stator winding and permanent
magnet temperatures are determined by a simplified
thermal lumped element network model with only two
time constants. Due to the structure of the model and the
measured stator core temperature the proposed thermal
model is very robust. Distortion of the cooling circuit
are inherently sensed such that the model can be used
for the online prediction of temperatures. Experimental
results based on an interior permanent magnet synchronous
machine are presented to validate the presented model.
