Abstract: A surface insulating material includes three or more individual layers that are stacked on top of one another. The surface insulating material has a longitudinal extent, a transverse extent and a radial extent, in such a way that the individual layers have different dimensions at least in the transverse extent.

Abstract: In a method for mounting a prefabricated form-wound coil or tooth-wound coil on a layered laminated core to form a stator segment or stator, the form-wound coil or tooth-wound coil is insulated with insulation. Laminates are punched and stacked to form partial laminated cores and/or a laminated core, with the partial laminated cores being spaced apart from one another by spacers and forming substantially axially extending open slots of the laminated core. The form-wound coil or tooth-wound coil are radially inserted into the slots such as to embrace a tooth of the laminated core, and a removable auxiliary element is placed at an axial end face of the laminated core to protect the insulation of the form-wound coil or tooth-wound coil as the form-wound coil or tooth-wound coil is radially inserted into the slots. The auxiliary element is radially removed and repositioned on a further tooth of the laminated core.

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.
