Abstract
A drive device for driving a watercraft is provided. The drive device has a stator and has a rotor which, during operation, rotates relative to the stator about an axis of rotation. The axis of rotation is fixed in position in relation to the stator. The rotor is realized as an internal rotor. The rotor, at least during operation, is supported on the stator in the axial direction by means of a first axial bearing means.
Claims20
A drive device for driving a watercraft, the drive device comprising:
- a stator;
- a rotor which rotates relative to the stator about an axis of rotation that is fixed in position in relation to the stator, and wherein the rotor is an internal rotor supported, at least during operation, on the stator in the axial direction by a first axial bearing means,
- wherein the first axial bearing means has at least one first rotor magnet device arranged on the rotor to realize a first rotor magnetic field, and wherein the first axial bearing has at least one first stator magnet device arranged on the stator to realize a first stator magnetic field, and realizes a first bearing force that, owing to the first rotor magnetic field and the first stator magnetic field, acts between the first rotor magnet device and the first stator magnet device and at least partially in the axial direction.
