Abstract: A rotor for an electrical machine includes a first shaft part and a second shaft part, which is arranged separately from the first shaft part. A first supporting element is connected in a manner fixed against rotation to the first shaft part, and a second supporting element is connected in a manner fixed against rotation to the second shaft part. The rotor has a yoke which connects the first supporting element to the second supporting element and includes a plurality of laminates arranged one behind the other, and which has cutouts extending in the direction of the axis of rotation in the interior of the yoke, and permanent magnets arranged in the cutouts. The yoke has holes extending in the direction of the axis of rotation, with tensioning pins extending through the holes in the yoke to brace the laminates.

Abstract: In order to allow a rotating electrical machine, which uses a permanent-magnet rotor with a flux-concentration construction for a rated power of more than 100 kW, to be assembled as easily as possible, two mutually adjacent half-yokes of two poles as well as magnets arranged between them in each case form a pole element which can be fixed on its own on the rotor body.

Abstract: In a rotating electrical machine having a permanent-magnet rotor, the tubular, highly thermally conductive supporting body of the stator forms a thermal bridge to a cooling means. In order to allow the end windings of the stator windings to be cooled effectively as well, the end windings also each have an associated thermal bridge, which completely fills the space between the end windings and the supporting body of the stator. This thermal bridge is of solid construction having a solid ring, which is connected to the supporting body of the stator with a force fit, and a cast-resin body which is cast into this solid ring. The cast-resin body has a thermal conductivity of more than 1.6 W/mK and, for this purpose, contains a powdery, highly thermally conductive filler making up a proportion of 50 to 90% by weight, preferably an aluminum nitride coated with silicon dioxide.

Abstract: An electric propulsion pod for a ship having a electric propulsion pod heat rejection member. The electric propulsion pod is attached below the ship by a hollow ship access shaft. The electric propulsion pod contains an electric motor for producing a water propulsion. The electric motor generates an amount of heat that is conducted and subsequently released into the water through the electric propulsion pod and ship access shaft surfaces. The heat rejection member is fitted for increasing the conduction and subsequent release of the electric motor heat.

Abstract: In an electromotive drive system in an improved form of a propeller motor for a ship, the cooling of the motor in a simple manner is provided. For re-cooling a circulating coolant, an annular duct is provided, which is arranged inside a shaft-like supporting part on its wall. With the assistance of this supporting part, the propeller motor is arranged, gondola-like, on the lower side of the ship.
