The arrangement of an electric machine, a connecting system and a converter, includes the connecting system connected between the electric machine and the converter. The connecting system has an enclosure that houses non-shielded conductors each non-shielded conductor is connected between a phase of the electric machine and the inner side of the converter. The non-shielded conductors of the connecting system that are connected to an operating phase of the electric machine are adjacent to conductors of the connecting system that are not connected to operating phases of the electric machine.

Connecting system for connection of an electric machine to a converter

Apparatus for producing electrical power from mechanical power, includes an electric generator with a rotor and with a stator. The electric generator is configured for conversion of mechanical power into a polyphase alternating current. The polyphase alternating current has more than three phases. The stator has a stator core with a stator bore. The stator core provides a plurality of stator slots arranged at a distance from one another. A plurality of coil portions are inserted in the stator slots, and the coil portions are connected to form coils. The coils include a plurality of Z-shaped portions and are laid out in a wave pattern.

The electrical connection of a sealed electrical machine is provided and includes a casing containing lead conductors each connected to a bushing via an electrical connector. The casing has at least an inlet and an outlet for a cooling fluid. The electrical connector includes at least a permeable element defining a chamber such that during operation the cooling fluid, passing through the chamber and the permeable element, cools the permeable element. A method is also provided for cooling an electrical connection.

A horizontal-axis electrical machine has an built-in stator concentrically surrounded by a number of parallel retaining rings that spaced apart from one another in the axial direction and are connected on their outer circumference on opposing sides in each case by means of retaining structures to a base frame which extends in the axial direction. A horizontally acting spring, which has the form of a perpendicular, longitudinal plate, is fixed on the one hand with its ends to the associated retaining ring, and is firmly connected on the other hand with its freely flexible central part to the base frame by means of connecting elements, being provided within each of the retaining structures. Improved oscillation isolation between the built-in stator and the base frame is achieved in such an electrical machine by vertically acting spring elements disposed between the ends of the spring and the associated retaining ring.
