The present invention relates to a spoke rotor for an electric machine, having a main body which extends concentrically around an axis of rotation and which has a plurality of pole shoes, between which permanent magnets are arranged in holders, wherein there is provided for each permanent magnet in its holder in each case at least one first clamping element and one second clamping element, which fixes said permanent magnet in the holder, wherein the first clamping element fixes the permanent magnet in a radial direction relative to the axis of rotation and the second clamping element fixes it in a tangential direction relative to the axis of rotation, and wherein in each case a movement clearance is provided for each second clamping element. The present invention also relates to a clamping lamella, in particular for such a spoke rotor. The present invention also relates to an electric machine comprising such a spoke rotor. The present invention also relates to a device, in particular a hand-held power tool, an adjustment drive for a motor vehicle, a power steering system, a servo motor, an electromechanical brake booster or a vehicle drive, comprising such an electric machine.

Es wird ein als Stator oder Rotor eingesetztes Hauptelement einer elektrischen Maschine angegeben, das ein aus SMC-Material hergestelltes Rückschlussjoch (11) und damit einstückige, am Rückschlussjoch um gleiche Umfangswinkel gegeneinander versetzte Zähne (12) aufweist. Jeder Zahn (12) besitzt einen vom Rückschlussjoch (11) radial abstehenden Zahnschaft (13) und einen am jochfernen Ende des Zahnschaftes (13) allseits über diesen überstehenden Zahnschuh (14). Zur Erzielung eines minimalen Rastmoments des Motors bei Sicherstellung einer einfachen Fertigung und Montage des Hauptelements sind die Zahnschuhe (14) als identische, gleichschenklige Trapeze ausgeformt, die an aufeinanderfolgenden Zähnen (12) so ausgerichtet sind, dass einander zugekehrte Trapezschenkel mit Spaltabstand parallel zueinander verlaufen (Fig. 1).

The invention relates to a strip transmission line (6) for producing a tooth-wound coil (1) for an electric machine, said strip transmission line (6) comprising at least one section (A2), in the longitudinal direction, in which the strip transmission line (6) is widened in the direction of a width (b) of the strip transmission line (6), defining two edges (11, 12), only one of said edges (12) having a bulge for widening the strip transmission line (6). The invention also relates to a tooth-wound coil (1) comprising a winding of the above-mentioned strip transmission line (6), such that the winding surrounds a winding axle with at least one turn in a winding position, the direction of the width of the strip transmission line (6) being oriented, in a winding plane, perpendicularly to the winding axle of the tooth-wound coil (1).
