1. A system for recovering waste heat energy for a motor assisted turbocharger, comprising:
a turbine;
a drive gear, a motor gear drivingly connected to the drive gear, and an output gear drivingly connected to the motor gear;
a first power transmission device connected on a first side to the turbine, and the drive gear disposed about and connected to a second side of the first power transmission device;
a second power transmission device connected on a first side to a side of the drive gear opposite the first power transmission device;
a compressor connected to a second side of the second power transmission device;
a motor generator connected to the motor gear;
a waste heat recovery circuit including an expander, the output gear connected to the expander;
wherein, in a case where the first power transmission device is engaged, engine exhaust gas drives the turbine, and the turbine drives at least one of the compressor and the motor generator.
