摘要： An electric machine has grooves and windings, divided into strands, of electrical conductors. At least one strand has a number s of coils connected in series and arranged in the grooves. Each coil has sub-conductors connected in parallel and arranged in bundles. Each bundle is arranged in a groove at a bundle position relative to a deepest possible bundle position in the groove. The positions of all bundles in all coils define a number b of possible bundle positions of the strand. The bundles are interchanged between the coils such that each bundle is arranged in the grooves at least n times and at most n′ times at each possible bundle position, wherein n is the integer quotient in regard to the quotient of the number s and the number b, wherein n′=n if s is divisible by b and n′=n+1 if s is not divisible by b.

摘要： The invention relates to a fluid-cooled active part (1) for an electric machine (38), wherein the active part (1) is substantially cylindrical or hollow cylindrical, having axially extending grooves (2), at least one electrical conductor (3), which is arranged in the associated groove (2) at least in some sections and which is composed of a plurality of partial conductors (4), one or more main insulators (5), each arranged between the associated conductor (3) and the associated groove (2), and partial-conductor insulators (6), each surrounding the associated partial conductor (4). The invention further relates to an electric machine (38), having such a fluid-cooled active part (1) designed as a stator (39) and/or such a fluid-cooled active part (1) designed as a rotatably mounted rotor (40), wherein the electric machine (38) can be operated with a voltage in the range of at least a few kilovolts, preferably a few tens of kilovolts. Finally, the invention relates to a drive System (41), having such an electric machine (38) and a fluid energy machine (42) for the fluid, wherein the fluid energy machine (42) is designed as a compressor, in particular for process gas, or as a pump, in particular for a process liquid. In order to provide, among other things, a high-performance fluid-cooled active part that is compact and, in particular, resistant in the environment of the fluid or of a process fluid, it is proposed, among other things, that the active part (1) has one or more cooling Channels (7) for conducting the fluid, in particular a process fluid, wherein each cooling Channel (7) is arranged between the associated main insulator (5) and the respective partial-conductor insulators (6).

摘要： An electric machine has grooves and windings, divided into strands, of electrical conductors. At least one strand has a number s of coils connected in series and arranged in the grooves. Each coil has sub-conductors connected in parallel and arranged in bundles. Each bundle is arranged in a groove at a bundle position relative to a deepest possible bundle position in the groove. The positions of all bundles in all coils define a number b of possible bundle positions of the strand. The bundles are interchanged between the coils such that each bundle is arranged in the grooves at least n times and at most n′ times at each possible bundle position, wherein n is the integer quotient in regard to the quotient of the number s and the number b, wherein n′=n if s is divisible by b and n′=n+1 if s is not divisible by b.

摘要： An active part of an electric machine includes at least two teeth, each having a magnetically permeable material and protruding from a lateral surface of the active part in a radial direction. Each tooth has an open recess in a plane spanned by a substantially radial direction and a direction substantially along an axis of rotation. A winding groove is arranged between the two teeth substantially along an axis of rotation of the active part for receiving an electrical winding. Arranged at least partially in the open recess is a thermally conductive element having a thermally conductive material with a thermal conductivity which is greater than a thermal conductivity of the magnetically permeable material.
