Abstract: A tooth-wound coil of a stator or of a stator segment of a dynamo-electric machine having two straight sections spaced apart from each other and running substantially parallel. Two 180° curves are located on the ends thereof, wherein the straight sections have an active part area, the axial extend of which is less than or equal to that of the straight section. The tooth-wound coil has a symmetrical extension plane running in the longitudinal direction. An insulation material is provided around the straight sections of the tooth-wound coil. The material effects groove isolation and/or phase isolation in the stator or stator segment.

Abstract: A magnetically active unit of an electric machine with at least two poles includes a laminated core with slots, and at least one winding for each of the phases. The windings have an electric conductor which forms coil groups in the slots. The coils of the coil groups are formed with at least two sections of the electric conductors of at least one of the windings and are arranged so as to be electrically insulated from each other in the grooves. At least one first coil group of the coil groups of one of the windings has a first number of coils which deviates from a second number of coils of a second coil group of the coil groups of the same winding.

Abstract: A stator segment of a stator of a dynamoelectric machine includes slotted laminations arranged axially one behind the other, such that substantially axially extending slots are formed. Coils are arranged in the slots, wherein one coil side or two coil sides of different coils are arranged in a slot. The laminations have at least one open slot on their outer boundary sides parallel to the slot. The coil sides are fixed in the open slots by an amagnetic fastener on the stator segment.

Abstract: An electrical conductor has two or more sub-conductors which are insulated from each other by virtue of the fact that the sub-conductors have merely one insulation layer with respect to the one or more adjacent sub-conductors. Each sub-conductor or the conductor is surrounded by a bandage of polyester fibers and glass fibers or only glass fibers.

Abstract: An active part of an electric machine includes a plurality of coils, each having a sub-conductor. The coils are formed by windings of the sub-conductors thereof. The windings of a coil each have a predetermined winding length. In addition, the active part has a carrier part, in the grooves of which, the coils are arranged. The coils have a winding head region which projects from an end surface of the carrier part. The coils are also arranged in the form of a tiered winding. At least one of the coils has a V-shaped cross-section in the winding head region, as a result of an arrangement of its sub-conductor.

Abstract: Electric machine has a rotor movable relative to a stator divided into stator segments, each having first and second transition regions and a central region between the transition regions. The stator segment has a yoke extending over the central region and the first transition region. Central groove webs in the central regions and first transition webs in the first transition regions extend from the yoke towards the rotor. The first transition webs end below the central groove webs. The stator segment has in the second transition region a transverse web from which second transition webs extend towards the rotor. The second transition webs end level with the central groove webs. A spacing of the first transition webs from the rotor at least corresponds to a spacing of a lower edge of the transverse web. Transition regions of adjoining stator segments overlap one another and are disposed one above the other.
