Abstract
The method of making a joint connection between exciter poles and the pole housing of an electrical machine includes positively displacing material of the pole housing (10) pointwise by means of the joining tool into a recess (22) provided in each of the exciter poles (12) at respective joining points to make a form- and force-locking connection of the exciter poles with the pole housing.
Claims10
A method of making a joint connection between exciter poles and a pole housing of an electrical machine by means of a joining tool, said method comprising the steps of:
- a) providing an exciter pole (12) having a recess (22) at a joining point on a pole housing (10);
- and
- b) positively displacing material of the pole housing (10) and of the exciter pole (12) pointwise by means of joining tool (20) into said recess (22) of said exciter pole (12) at said joining point to make a form- and force-locking connection of the exciter pole (12) with the pole housing (10).

- and
- b) positively displacing material of the pole housing (10) and of the exciter pole (12) pointwise by means of joining tool (20) into said recess (22) of said exciter pole (12) at said joining point to make a form- and force-locking connection of the exciter pole (12) with the pole housing (10), so that a rivet (34) is displaced into said recess (22) from the pole housing (10) and an edge (32) of the recess (22) is displaced into a recess (24) during a joining process, and also an undercut (33) of the rivet (34) is produced.
