Embodiment Construction

[0023] figure 1 The boat 102 shown in has four Magnus rotors 110 on deck 114 as propulsion means. In addition to the Magnus rotor 110 , the ship optionally has a nacelle 130 on deck 114 as well as cranes 105 and 103 . The boat additionally has a propeller 150 on the stern of the boat 102 as a further propulsion device. The boat propeller 150 can be connected via the shaft 111 to the two electric motors 108 , 109 . The electric motors 108 , 109 are fed via two converter cabinets 115 , 116 . A ceiling 172 is arranged above the electric motors 108 , 109 and the converter cabinets 115 , 116 , which closes the motor compartment preferably gas-tight from the cargo compartment. Large-volume electric motors with a low rotational speed, for example synchronous machines, are preferably used as electric motors 108 , 109 , so that a transmission does not have to be provided in the entire drive train. Furthermore, it is preferable to be able to selectively operate the motor. In order ...

Abstract

The invention relates to a ship (102) comprising at least one electric motor (8, 108, 109) for driving the ship (102), and a cooling device (1) for cooling the at least one electric motor (8, 108, 109) by means of at least one coolant. The invention also provides that the cooling device (1) has a heat exchanger (2, 3), which is designed for cooling the at least one coolant by means of seawater (16, 17).

Description

technical field [0001] The invention relates to a boat having at least one electric motor for driving the boat and a cooling device for cooling the at least one motor by means of at least one coolant. Furthermore, the invention relates to a cooling device for a ship having at least one electric motor. Background technique [0002] Until now, ships have been driven mainly by means of internal combustion engines. In smaller boats, for example in amusement parks, electric drives are also often used. More recently, attempts have also been made to drive larger ships, such as cargo ships or container ships, by means of electric drives. The climate at sea is a problem for drives which often have complex and complex electronics. In particular, the cooling of such electric drives for cargo ships is a hitherto insufficiently solved problem. Contents of the invention [0003] The object of the present invention helps to solve this problem, in particular to provide an electric mot...
