Definitions
- the portion with which the insulating coating is in contact to generate the circumferentially acting force F is also the insulating coating of the adjacent stator module.
- the insulating coating of each stator module is identical. That Each stator module has an insulating coating, which extends beyond the side surfaces of the pole piece to the same extent circumferentially. As a result, the end sections of both insulating coatings of adjacent stator modules meet approximately in the middle of the slot gap A. Both insulating coatings then form an elastic compression in the circumferential direction, from which the circumferentially acting force F results. But it is also conceivable that an insulating coatings of adjacent stator modules project beyond the side surfaces of the pole pieces at different distances.
- Figure 2 shows the area around the slot gap A as an enlarged section.
- the end sections 10 of the insulating coatings 5 applied on the back of the pole shoes 7 protrude in the circumferential direction approximately by the same amount over the side surfaces 8 of the respective pole shoes 7 in the case of two adjacent stator modules 2 (FIG. 1).
- the end portions 10 of the insulating coatings 5 abut each other in the circumferential direction and it forms in the assembled state of the stator in both end portions 10 a compression S from.
- This compression causes due to the elasticity of the material of the insulating coating 5, a force F, which acts in the circumferential direction of the pole teeth.

Abstract
L'invention concerne un stator (1) composé de plusieurs modules de stator (2) se trouvant en connexion, formant des rainures d'enroulement (3) dans lesquelles des enroulements de stator (4) sont logés. Un revêtement électro-isolant (5) se trouve dans les rainures d'enroulement (3), entre les modules de stator (2) et les enroulements de stator (4). Les cornes polaires (7) comportent des surfaces latérales (8) présentant un espace de rainure (A) dans la direction périphérique, par rapport aux surfaces latérales opposées (8) des cornes polaires (7) de modules de stator voisins (2). Le revêtement électro-isolant (5) d'au moins un module de stator (2) fait saillie par rapport à au moins une surface latérale (8) de la corne polaire (7) dans la direction périphérique et se trouve en contact avec une section du module de stator (2) voisin à l'état monté du stator (1), de manière à produire une force (F) agissant sur les dents polaires (9). L'invention concerne également un procédé de réduction des vibrations des dents polaires (9) d'un stator du fait que les revêtements isolants (5) des modules de stator (2) produisent une force (F) sur les dents polaires (9) de modules de stator (2) voisins.
