| Abstract |
Sensorless control of Permanent Magnet
Synchronous Machines is popular for several reasons: cost saving
and system reliability. The basis for most low and zero speed
sensorless control is that there exist a difference in the direct and
quaderature inductance of the machines. This difference is also
reefed to as saliency. In this paper the different contributors to
the resulting saliency is modeled. This type of modeling is useful
for several reasons: increased understanding of the fundamentals
of sensorless control, incorporating the combined effects of
leakage and main inductance variations, incorporating the effects
of loading of the machine and finally it gives valuable insight
when the saliency ratio is attempted increased by machine
design.
