Abstract
(EN)
This electric motor system (2) is provided with: a drive shaft (30) rotatable about the axial center; a first electric motor (60) and a second electric motor (70) each rotationally driving the drive shaft (30); a first inverter (91) for supplying power for generating torque to the first electric motor (60); a second inverter (92) for supplying power for generating torque to the second electric motor (70); and a control unit (80) configured so as to control the first inverter (91) and the second inverter (92) and be able to change the ratio between the output torque of the first electric motor (60) and the output torque of the second electric motor (70).
(FR)
