AIRCRAFT POWERPLANT WITH ELECTRIC MACHINE SYSTEM

An aircraft powerplant (20) assembly includes a gearbox (102), a first electric machine (90A), a first electric cable (112A), a second electric machine (90B) and a second electric cable (112B). The first electric machine (90A) is mounted to the gearbox (102) at a first side (135A) of the gearbox (102). A first machine terminal (132A) is disposed at a first side (130A) of the first electric machine (90A). The first electric cable (112A) is electrically coupled to the first machine stator (96A) through the first machine terminal (132A). The second electric machine (90B) is mounted to the gearbox (102) at the first side (135) of the gearbox (102). A second machine terminal (132B) is disposed at a second side (130B) of the second electric machine (90B) that faces the first side (130A) of the first electric machine (90A). The second electric cable (112B) is electrically coupled to the second machine stator (96B) through the second machine terminal (132B).
