Abstract: 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.

Abstract: Embodiments of the present invention relate to a winding of a rotor for use in rotating electrical machines. More particularly, embodiments of the present invention relate to innovative half-coils used for the winding of the rotor. Moreover, embodiments of the invention pertain to a method for winding a rotor body of an electrical machine. According to embodiments of the invention, half-coils, instead of being manufactured as double hollow conductors, are provided in the form of two single hollow conductors, which are adjacently embedded within a respective slot of the rotor body.

Abstract: A stator winding of a directly cooled turbogenerator comprises directly gas cooled double Roebel bars is arranged as active parts in slots of a stator body. Each double Roebel bar has two single Roebel bars, which includes each a stack of a plurality of transposed individual strands, and are separated by an intermediate stack of cooling tubes. Mounting space is saved by constructing, for the compensation of stray field voltages, at least one double Roebel bar as a cross-over bar with the strands being transposed over the stack of cooling tubes in the middle in order to change the sides of the single Roebel bars along the active part.
