    Abstract: An arrangement is disclosed for supplying propulsion power to a contra rotating propellers (CRP) propulsion system in a marine vessel, which arrangement can include a first propeller driven by a rotating power unit, and a second propeller driven by an AC motor. The second propeller can be rotated in an opposite direction relative to the first propeller, wherein an AC generator is driven by the rotating power unit and the AC generator is electrically connected to the AC motor. The rotation speed of the second propeller is between for example 95% and 150% of the rotation speed of the first propeller. The AC motor and the AC generator have the same electrical frequency. The pole number of the AC generator is from for example 2 to 40 and the pole number of the AC motor is from for example 2 to 40.

    Abstract: A stator winding is disclosed for a multiple-phase alternating current machine with several parallel winding groups (U1, V1, W1; U2, V2, W2; U3, V3, W3), each of which can be supplied with separate power sources. Locations of the winding groups can be cyclically shifted when moving from one pole to another. The number of parallel winding groups (U1, V1, W1; U2, V2 ,W2 ;U3 ,V3 , W3) can be higher than two, and the number of poles of the alternating current machine can be an even figure that is a multiple of the number of winding groups.
