Abstract
In some examples, at least one connecting ring may connect a plurality of stator coils of the same phase. For instance, the at least one connecting ring may include at least one linear conductor formed in a ring-like shape. The linear conductor may include a plurality of terminal sections, each terminal section including an open groove extending perpendicular to a plane formed by the ring-like shape. The open grooves may be positioned around a circumference of the connecting ring for receiving respective wire ends of respective stator coils inserted into the open grooves for forming an electrical connection between the respective wire ends and the connecting ring at the respective terminal sections.
