| Summary: | This paper looks in detail at a fault tolerant machine
for direct drive application. The machine considered is a high pole
number, concentrated wound machine developed for a safety
critical aerospace application. The machine is designed to have a
high p.u. inductance to limit short circuit current and negligible
mutual inductance to have decoupled phase windings. Single and
double layer winding configurations are compared. The machine
has a heavy magnetic loading as its most onerous requirement is
to hold a static load. High resulting air gap harmonics however
induce substantial eddy current losses in the magnets and the
solid rotor core. Due to the high thermal resistance path to these
losses, the magnets may reach limiting temperatures during
dynamic operation. This paper is set to analyze and compare two
winding configurations and employ analytical modeling methods
to evaluate the induced eddy current loss in the rotor. |
