- this has a brake for braking the drive shaft.
- the brake can then be used to re ⁇ duz réelle a speed or as a parking brake.
- the auxiliary machine can be switched off with active brake.
- the auxiliary machine can also be used as a brake himself ⁇ the. With a speed setpoint of 0, the auxiliary machine can also serve as a parking brake.
- the brake, or a braking ⁇ device allows to keep occurring moments at any desired position.
- the ship propulsion in particular of the electric ship propulsion, there is an external energy supply connection for the auxiliary engine.
- the Hilfsma ⁇ machine is a motor, which is fed, for example via the power ⁇ network in a shipyard or a port. So you do not need to connect the engine with the electrical system of the ship. During docking times, the ship's power supply may not operate or may not operate properly.
- the external power supply which is therefore not fed by the island grid of the vessel, the Pro ⁇ pellerwelle can gymnastics using external auxiliary means (overall rotates) are.

- a power supply terminal 26 serves to supply the auxiliary machine 8 and / or the controller 20 with electrical energy.
- This electrical energy can, for example, in the ship associated with the ship propulsion be generated or taken from an electrical supply network in the port or dock. If the electrical energy comes from the ship, you are independent of a shore connection, ie independent of an electrical network in a harbor or a dock. If the electrical energy for the auxiliary machine 8 comes from outside, ie from a network or from an external generator unit with an internal combustion engine, then one is independent of the operating state of the ship. This can be advantageous, for example, if the generation of electrical energy on the ship is shut down for maintenance work.
- FIG. 2 shows, similar to FIG. 1, an electric ship drive 2 with a drive machine 4, which is constructed like the drive machine 3 according to FIG.
- the prime mover 4 is located in the POD 13, which is rotatably mounted on the shaft 29 on a hull 23.
- the shaft 29 is hollow and can, for example ⁇ record electrical supply lines.
- the housing opening 15 is positioned laterally. This facilitates the handling when the distance to the ground is low in a Tro ⁇ ckendock.
- the auxiliary machine is not shown in FIG 2, but the pulley or sprocket 16 is visible.
- FIG. 3 shows a ship in a dry dock 24 27.
- the auxiliary engine 8 can be supplied via an external Ener ⁇ gietrays 28 with electrical energy. So one is independent of the operating state of the power generators in the ship 27th
