The interest in electrical machines is spread in
a large area of applications.
For this reason the purpose of this project
is to investigate the nonlinear phenomenon
in buried permanent magnet synchronous ma-
There is a dierence in the direct and quadra-
ture inductance of the machines. The induc-
tance variation is investigated to observe the
saliency which is based on the inductance in
the d and q axis of machine. The d-axis in-
ductance and q-axis inductance and torque are
determined from a static test.
A model of the IPMSM whitch include satura-
tion is done. The model is based on laboratory
data. Field Oriented Control was implemented
and tested on the IPMSM.
For validating the control, the laboratory and
simulations results are compared.
