Abstract
A POD drive unit for a marine vessel has a housing, a first axial flux motor connected with a first shaft so as to rotate with a first rotation speed, a second axial flux motor connected with a second shaft so as to rotate with a second rotation speed. The first and second axial flux motors are arranged inside the housing. The first shaft and the second shaft are connected with a pitchable propeller. A coupling is arranged between the first shaft, the second shaft and the pitchable propeller for changing a pitch angle of the pitchable propeller when the first rotation speed and/or second rotation speed vary in relation to the other.
