Zusammenfassung:	A fan assembly 30 includes a fan 26, 28, 32 and a fan drive 46. The fan includes a fan hub 34 located at a fan central axis 36, and a plurality of fan blades 38 extending outwardly from the fan hub 34. The fan hub 34 has a fan hub opening 48 at the fan central axis 36. The fan hub opening 48 is at least partially defined by a plurality of nodes 52 extending radially inwardly toward the fan central axis 36 from the fan hub 34. The fan drive 46 is installed in the fan hub opening 48 via an interference fit between the plurality of nodes 52 and an outer surface of the fan drive 46, thus centering the fan drive 46 in the fan hub opening 48.
