Abstract

A fluid compressor device includes a housing and a rotating group supported for rotation within the housing about an axis. The device also includes a compressor stage including a compressor wheel of the rotating group that is supported on a shaft of the rotating group. The device also includes an e-machine stage including an e-machine that is operably coupled to the shaft and that is configured to operate as at least one of a motor and a generator. Additionally, the device includes an integrated controller that extends at least partly over the e-machine stage in a circumferential direction about the axis. The integrated controller includes a coolant core that receives a flow of a coolant therethrough for cooling the integrated controller. The coolant core extends over the e-machine stage in a circumferential direction about the axis.
