Stator of an electrical machine

摘要

Stator of an electrical machine includes a stator lamination stack, having coil forms fastened thereto which each include an electrical coil. The coil forms are each pressed onto a tooth of the stator lamination stack. For the fastening of the coil forms to the teeth of the stator lamination stack, at least one fastening element is provided at the two end faces of the stator lamination stack, which fastening element includes a fastening arrangement which cooperate in a form-locking manner and/or force-locking with coil forms.

主权项

1. A stator of an electrical machine, comprising:
a stator lamination stack that forms a plurality of teeth arranged side-by-side in a ring, wherein, with respect to each of the teeth, the respective tooth includes (a) two side faces that each faces a side face of another one of the teeth that is adjacent to the respective tooth, (b) a top face, and (c) a bottom face, wherein the top faces of all the teeth together form a flat plane defining a top end face of the stator lamination stack, and the bottom faces of all the teeth together form a flat plane defining a bottom end face of the—stator lamination stack; coil bobbins fastened to the teeth of the stator lamination stack, wherein each coil bobbin includes an inner surface surrounding one of the teeth and an outer surface onto which an electrical coil is wound; and at least one fastening element provided at each of the top and bottom end faces of the stator lamination stack, wherein the at least one fastening element includes radially inwardly projecting lugs, which each (a) includes a latching spring or a locking hook, and (b) cooperates in at least one of a form-locking manner and a force-locking manner with the inner surface of one of the coil bobbins.
