Embodiment Construction

[0025] figure 1 A part of an annular stator core 10 for an electrical machine not shown is shown. The stator core 10 has a large number of first teeth 11 and second teeth 12 which are arranged alternately on the inner side of the annular stator core 10 . In other words, the first and second teeth 11 , 12 protrude on the inner side of the stator core 10 . In this case, the first teeth 11 are narrower on the inner side of the annular stator core 10 than at the bottom of the stator teeth 11 , where the first teeth 11 are connected to the stator core 10 . connected. In contrast, the second teeth 12 are equally wide not only on the inner side of the stator core 10 but also on its base.

[0026] exist figure 1 A coil 20 with a coil holder 30 having a first and a second coil holder 31 , 32 has been mounted on two of the second teeth 12 . as in figure 1 A further coil 20 wound on a further coil holder 30 can be arranged on the first tooth 11 of the stator core 10 , as indicated ...

Abstract

The invention relates to a coil holding member for holding a motor coil and a method for manufacturing a motor stator. A coil holding member (30) for holding a coil (20) for a motor and a method for manufacturing a stator for the motor are provided. The coil holding member (30) comprises first and second cold racks (31, 32) for being installed on a stator section (12) in this manner, and the first and second cold racks (31, 32) are used to hold the coil (20) on the stator section (12) and configured to separate the coil (20) and the stator section (12).

Description

technical field [0001] The invention relates to a coil holder for holding a coil for an electric machine and a method for producing a stator for an electric machine. Background technique [0002] Currently, the coils are mounted on the ring-shaped stator core having at least one stator tooth with an insulating sheath made of a composite material, also known as insulating paper. [0003] EP 0 938 181 A1 shows a three-phase AC motor with a stator having segmented partial plate packs in the circumferential direction of the motor and / or in its axial direction, the The segmented partial plate pack then has at least one stator tooth and means for fastening in a receptacle with a cylindrical or polygonal inner contour. [0004] The stator of the electric machine, which is wound with windings or coils, has a thermal resistance which is decisively determined by the insulating material used. Insulation materials used today generally have thermal conductivity in the order of 0.25 W / (...
