The present invention relates to an electric machine (1) having a rotor (3) and a stator (2), wherein the stator (2) and/or the rotor (3) has an electrical plug-in winding (4), which comprises a plurality of rigid insulated electrical conductor elements (5); the conductor elements (5) are arranged in grooves of the stator or of the rotor and their conductor ends (17) project out of the grooves; the conductor ends of the conductor elements (5) are each connected to conductor ends of other conductor elements (5) in order to form the electrical plug-in winding (4); the conductor elements (5) have an electrically insulating insulation sheath (9); characterized in that each conductor element (5) has a multiplicity of flexible fibres (8), in particular of a conductor strand of flexible fibres (8), made of carbon nanotubes or graphene and in that the insulation sheath (9) surrounds the multiplicity of fibres (8) like a hose and is designed in such a way that it gives the electrical conductor element (5) a rigid form.

A device and a method for manufacturing the device for driving a compressor, in particular an electric motor, with a rotor and a stator with a stator core, which are arranged along a longitudinal axis. The stator exhibits connecting cables produced as sections of conducting wires of coils, and connection lines, that are arranged on a first end face of the stator, one insulation element whose wall that is produced essentially with a hollow-cylinder shape projects beyond the stator core on the first end face of the stator in the axial direction, as well as one cover element with mounting elements with connection passages for mounting plug-in connectors, which each are fully enclosed by a wall. A volume enclosed by the stator core, the cover element and the wall of the insulation element which projects beyond the stator core is filled at least zonally with potting compound.

A stator is improved in work efficiency of mounting to a stator core is provided. The stator includes insulators sandwiching the stator core therebetween. The stator core includes a plurality of teeth that radially projects. Each of the insulators includes a plurality of tooth covering portions that radially projects. The tooth covering portions cover the teeth. In a facing portion of one of the insulators facing the stator core, a peripheral portion projects more than a center portion. In a facing portion of the other of the insulators facing the stator core, a center portion projects more than a peripheral portion.
