This has the advantage that the rotor can be made very long in relation to its diameter, so that the angle of inclination of the copper conductor to the surface lines is very small.

Das hat zur Folge, daß der größte Teil der entstehenden auslenkenden Kräfte in Umfangsrichtung wirkt und damit zum Nutzmoment beiträgt. Außerdem können auf diese Weise lange Bauformen mit kleinem Durchmesser, wie sie für manche Zwecke vorteilhaft oder erforderlich sind, verwirklicht werden.As a result, most of the resulting deflection Forces acts in the circumferential direction and thus contributes to the useful torque. Also can in this way long designs with a small diameter, as they are for some purposes advantageous or necessary.

Die Erfindung sei an einem in der Zeichnung angegebenen Ausführungsbeispiel näher erläutert. Dabei sind in den Fig. 1 und 2 mit 1 die Rotorwelle,., mit..-2 der . mit 3 die Isolierstoffscheiben, mit denen die Wicklung 4 auf der Rotorwelle 1 abgestützt ist, mit 5 der Erreger- magnet und mit 6 die Lagerstellen, an denen der Erregermagnet 5 drehbar auf der Rotorwelle 1 gelagert ist, bezeichnet. Fig. 1 zeigt einen Rotor in der Ansicht. Darin ist die Wicklung 4 so dargestellt, wie sie sich bei obenbeschriebener Drahtführung ergibt.The invention is based on one indicated in the drawing Embodiment explained in more detail. Thereby are in the Fig. 1 and 2 with 1 the rotor shaft,., With ..- 2 the . with 3 the insulating disks with which the winding 4 is supported on the rotor shaft 1, with 5 the exciter magnet and with 6 the bearing points at which the exciter magnet 5 is rotatably mounted on the rotor shaft 1, denotes. Fig. 1 shows a rotor in the view. The winding 4 is shown therein as it results from the wire guide described above.

Fig. 2 ist eine Schnittdarstellung des Rotors. Die Wicklung 4 ist durch die Stützscheibe 3 fest mit der Rotorwelle 1 verbunden. Innerhalb der Motorwicklung 4 befindet sich der Dauermagnet 5, der mittels der Lager stellen 6 auf der Welle frei drehbar gelagert ist.Fig. 2 is a sectional view of the rotor. The winding 4 is firmly connected to the rotor shaft 1 by the support disk 3. Inside the motor winding 4 is the permanent magnet 5, which is set by means of the bearings 6 on the shaft is freely rotatable.
