We are developing a Permanent Magnetic
Synchronous Machine (PMSM) for being used
inside a cryostat. This environment is characterized
by ultra high vacuum (UHV) and operating
temperatures down to 80 K. In order to optimize our
current design, we have been performing a design
study about the key parameters of the machine. One
of the challenges that we were confronted with is the
analysis of thermal behavior during operation of the
motor. Its power consumption will generate heat and
thermal gradients within the motor might change the
performance. Therefore, the temperature profile
inside the machine generated during operation has
been analyzed and the results are shown in this
paper. The objective is to find an ideal configuration
for the PMSM with respect to heat generation and
cooling during operation. A design optimization
methodology has been developed using the
COMSOL Multiphysics® Joule Heating physics. For
a parametric study, electromagnetic properties are
calculated in MATLAB® and implemented into the
model using the respective LiveLink™.
