Abstract
A supercharger for boosting intake manifold pressure in an internal combustion engine and producing electrical energy comprises an input shaft (3), a electric machine (50) including a stator (51) and a rotor (53), a compressor (70) including an impeller (71), and a planetary transmission (30) located between the input shaft (3) and the rotor (53) of the electric machine (50) and the impeller (71) of the compressor (70), all such that the input shaft 3 can drive both the impeller (71) and the rotor (53), or the rotor (53) and input shaft (3) can drive the impeller (71). The planetary transmission (30) includes an outer ring (31) operatively coupled to the input shaft (3), a sun member (39) operatively coupled to the impeller (71), planetary clusters (38) located between the outer ring (31) and sun member (39), and a carrier (37) operatively coupled to the planet clusters (38) and the rotor (53). Each planetary cluster (38) comprises an inner roller (35) and an outer roller (33).
