Abstract (en)
[origin: WO2018141492A1] The invention relates to a stator for an electric machine, comprising an annular laminated core (2) with a longitudinal axis (3) and multiple grooves (4), each of which extends along the longitudinal axis (3). The coil of the stator comprises at least three phases (U, V, W) with two respective sub-sections (13), said phases being distributed into multiple rings (20, 21, 22) in the radial direction. Coil wires (5) connected in series form a sub-section (13). Multiple wires (5) which are arranged in adjacent positions of the grooves (4) and form rings (20, 21, 22) form a power connection (9) for electrically connecting the stator (1). Each of the wires (5) is connected in pairs to an adjacent position in contacting regions (6) on the axial laminated core (2) end face, which is referred to as the contacting side (8). The power connections (9) are likewise arranged on said contacting side (8). The wires (5) have a hairpin shape for example, whereby the wires are closed on the ring side (11) opposite the contacting side (8).
