Abstract

A rotary electromechanical actuator, EMA, comprising: a first EMA part (1) comprising a first electric motor (12) and a first rotary shaft (S1) extending along an axis and arranged to be rotated about the axis by the first electric motor, and a first 1st stage gearbox (10) providing a geared transmission from the first electric motor to the first output shaft, and a first brake assembly (14) for applying a braking force to the first output shaft; the EMA further comprising: a second EMA part (2) comprising a second electric motor (22) and a second rotary shaft (S2) extending along the axis and arranged to be rotated about the axis by the second electric motor, and a second 1st stage gearbox (20) providing a geared transmission from the second electric motor to the second output shaft, and a second brake assembly (24) for applying a braking force to the second output shaft; and the EMA further comprising an output (40) arranged to rotate with rotation of the first shaft and the second shaft; the EMA further comprising a common stage gearbox (30) providing a geared transmission between the first and second shafts and the output (40), the common stage gearbox being located between the first and second 1st stage gearboxes; wherein the common stage gearbox comprises: a first sun gear (32) in engagement with and driven by the first shaft (S1) and a second sun gear (34) in engagement with and driven by the second shaft (S1); a first intermediate gear (33) driven by the first sun gear; a second intermediate gear (35) driven by the second sun gear; and an outer gear structure (36) arranged to engage with the first and the second intermediate gears; wherein the outer gear structure comprises: a first outer gear part (37) that extends across and engages both the first intermediate gear and the second intermediate gear; and a second outer gear part (38) that meshes with the first intermediate gear and is engaged with and drives the output (40).
