1. A method for connecting a housing cover to a housing cup for an electric machine, the housing cup defining an opening and having an opening edge surrounding the opening, the housing cover having a cup shape, and a collar of uninterrupted encircling form is integrally formed on a cup wall of the housing cover in a region of the opening edge, the collar projecting radially outwardly, the method comprising:
at least partially inserting the housing cover into the housing opening such that a channel is formed by mutually opposite regions of a housing cover wall and a housing cup wall; and
at least partially filling the channel with a sealing compound
wherein the at least partial filling of the channel with the sealing compound comprises inserting a dispensing device into the channel, which causes the sealing compound to flow into the channel,
wherein the dispensing device includes a dispensing pipe, and the at least partial filling of the channel further comprises:
circumferentially guiding the dispensing pipe around the housing cover in the channel; and
dispensing the sealing compound into the channel as the dispensing pipe is guided around the housing cover.
