Title: DRONE FOR TRIGGERING SEA MINES
Abstract:
A drone for triggering sea mines by means of an external magnetic field (Bext) is specified, - wherein the drone (1) comprises a drive with an electric motor (3) for propagating in water, - wherein the electric motor (3) comprises a stator (11) and a rotor (9) that is rotatably mounted on a rotor shaft (7), - wherein the stator (11) has at least one stator winding (17) which is arranged on a first carrier (19), - wherein the rotor (9) has at least one magnetic or electromagnetic element (15a, 15b, 15c) which can electromagnetically interact with the at least one stator winding (17) in such a way that, during operation of the electric motor (3), a superordinate magnetic field (B) is formed - and wherein the electric motor (3) is configured in such a way that, during the operation thereof, the external magnetic field (Bext) that is formed outside of the electric motor (3) has, in at least a portion thereof, a magnetic flux density of at least 0.5 mT at said location.
