Beschreibung
Zusammenfassung:	A system and apparatus for compression of an incoming feed air stream using at least two variable speed compressor direct drive assemblies controlled in tandem is provided. The first variable speed driver assembly directly drives at least one compression stage in the lower pressure compressor while the second variable speed driver assembly directly drives higher pressure compression stage disposed either in the common air compression train or the split functional compression train of the air separation plant. The first and second variable speed driver assemblies are preferably high speed, variable speed electric motor assemblies each having a motor body, a motor housing, and a motor shaft with one or more impellers directly and rigidly coupled to the motor shaft via a sacrificial rigid shaft coupling.
