  • Patent number: 9216804
    Abstract: Pod drive which can be fitted to a vessel and which is provided with an electric motor which drives a propeller shaft which is likewise provided in the housing of the pod drive and is connected to a propeller which is situated outside the latter. It is proposed to use a fast-rotating electric motor in combination with a reduction gearing for driving the propeller shaft. The mounting of the propeller shaft is made particularly stable by mounting it on both sides of the electric motor. The reduction gearing may include a planetary system. The electric motor may be fitted next to the hollow propeller shaft. In this case, several electric motors can be arranged around the central propeller shaft. It is also possible to make the rotor of the electric motor hollow and to fit the propeller shaft inside the latter.

  • Publication number: 20150158568
    Abstract: A vessel and a method for driving a vessel. The vessel is provided with a pod arranged at the rear side thereof which is arranged rotatably with respect to the vessel. Rotation is effected about an axis which deviates slightly from the vertical. The axis of the propeller shaft forms an angle which is smaller than 90° with the axis of rotation of the pod. As a result of this combined positioning of the rotation shaft of the pod and the positioning of the propeller shaft, the axis of the propeller shaft with respect to the horizontal will vary when the pod is rotated depending on the rotation position of the pod. This permits optimum adaptation to the various operating conditions of the propeller position.
