Abstract: A conductor bar including a plurality of Roebel-transposed conductor elements is disclosed. At least one of the conductor elements possesses a plurality of conductive strands stacked relative to each other. The strands used to form the at least one conductor element follow a common path within the conductor bar. An insulator electrically insulates the conductor elements from each other. Also provided are a method of manufacturing a conductor bar and an electric machine including a plurality of conductor bars.

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.

Abstract: A stator bar includes a substantially quadrangular conductive element made of a plurality of interwoven strands. The stator bar also includes an electric insulation applied around the conductive element and including a plurality of corners corresponding to corners of the conductive element. The electric insulation includes an inner insulation zone facing the conductive element, and an outer insulation zone surrounding the inner insulation zone. The radius of at least one of the corners is between 1.5-2.5 millimeters. Permittivity at the corners of the electric insulation decreases by 35-45% from the inner insulation zone facing the conductive element towards the outer insulation zone. The insulation includes at least one mica layer, where one of the at least one mica layer includes titanium dioxide (TiO2).

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.
