An example compressor arrangement includes a first compressor portion configured to compress a fluid and a second compressor portion configured to compress the fluid more than the first compressor portion. The compressor arrangement also includes a motor disposed between the first compressor portion and the second compressor portion. The first compressor portion is configured to communicate the fluid to the second compressor portion along a primary flow path. The second compressor portion is configured to divert at least some of the fluid from the primary flow path, communicating the diverted fluid back to the first compressor portion along a secondary flow path.
