More Information
Summary:The invention relates to a module (3) comprising a device (45) for changing the pitch of the vanes (30) about the pitch axes (C) thereof, the device (45) comprising: a hydraulic actuator (46) capable of rotating about the longitudinal axis (X) and configured to rotate the vanes (30) about their pitch axes (C), a pump (54) for supplying fluid to the hydraulic actuator (46), comprising a transmission shaft (54a) and a shell (54b) placed around the transmission shaft (54a) and rotating as one with the drive shaft (32), and an electric machine (55) comprising a rotor (56) rotating as one with the transmission shaft (54a) and a stator (57) rotationally fixed relative to the longitudinal axis (X), the stator (57) being connected to a power supply cable (62) passing through a passage (38a) provided in the third element (38) of the speed reducing gear (33).
