Embodiment Construction
[0042] figure 1 In , an example for a bobbin equipped according to the invention is indicated with reference numeral 100 , onto which bobbin a coil 200 according to the invention is wound. by figure 2The first perspective view in the first viewing direction illustrated by the arrow indicated by A shows the coil 200 and the coil former 100 . The viewing direction A largely approximates the radial direction of the machine, which is intended to be equipped with the coil, but is rotated by approximately 20 to 30 degrees in each case in the axial direction and in the circumferential direction of the machine. Here, the viewing direction A points outwards from the axis of rotation of the machine.
[0043] The bobbin 100 includes a linearly extending first slot section 101 and a linearly extending second slot section 102 . The first groove section 101 has a first axial end 103 and a second axial end 104 . In the same way, the second groove section 102 has a first axial end 105 an...

In order to realize the advantages of coils wound with rectangular conductors also for coils consisting of thinner conductors and in particular to provide a device by which distributed circuits can be produced in a simple, cost-effective and precise manner. Two-layer winding or multi-layer winding, a coil former (100; 121, 122, 123, 124) is proposed, which is intended for distributed coils (200; 211, 212) in the configuration of the electric machine as plug-in coils , 213, 214) to wind and accommodate at least one conductor, the plug coil is formed for insertion into the magnetic pole, and the plug coil defines the stator (300) or rotor having a through-axis The stator core and / or the rotor core (301) have stator teeth or rotor teeth (303) separated from each other by slots (302), wherein the coil former (100; 121; 122; 123; 124) has two slot sections ( 101, 102) and two winding head sections (107, 108), two slot sections constructed and determined for insertion into two non-contiguously located circumferential directions of the stator (300) and / or the rotor. In a continuous groove (302), two wrapping head sections connect the groove sections (101, 102) to each other at their axial ends (103, 104, 105, 106).
Description
technical field [0001] The invention relates to a bobbin for a motor coil. Furthermore, the invention relates to a coil with such a former. The invention also relates to stators, rotors and electrical machines with such coils. Background technique [0002] A coil, a stator of a rotating electrical machine and a method for producing the coil are known from DE 10 2012 201 698 A1, wherein the coil is arranged in the stator and the stator has a plurality of slots arranged in the circumferential direction. The coil has a first winding section which is formed by edge-winding an electrically conductive rectangular wire into a hexagonal shape. The first winding section has two first slot inserts which are respectively arranged in two first slots spaced apart from each other in the circumferential direction. The first winding section also has two first coil end pieces, which are connected to the two first slot inserts. The first slot is included in the plurality of slots of the s...
