Problems solved by technology

This causes a strong bending of the rectangular wire at the transition between the slot insert and the beveled area, but especially in the beveled area, thereby increasing the risk of damage to the lead wire or damage to the electrical insulation surrounding the wire, for example the varnish danger

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...

Abstract

In order to achieve advantages, which have coils wound from rectangular wires, and also for spools of thin conductors in particular, the invention provides a means by which distributed two or even multilayer windings can be produced simply, cost-effectively and precisely, a winding body (100; 121, 122, , 124), intended for winding with and receiving at least one conductor of a stator, which is designed as a magnetic pole and is separated from one another by axial grooves (302) (301) of a stator (300) and / or rotor core (301) having rotor teeth (303) or (100; 121, 122, 123, 124) has two groove sections (101, 102) which are adapted to be inserted into two coils (101, 211, 212, 213, 214) (101, 102) at their axial ends (103, 104, 104) are arranged in a circumferential direction of the stator (300) and / or rotor not immediately successive grooves (302), and two winding head portions (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...
