A rotary dynamoelectric machine includes a single- or multi-phase winding system, which is arranged in a stator and has winding connection lines which are guided into a terminal box for contacting external connection lines. The terminal box is located in a region of an end side of the stator, is recessed in a housing of the stator, and is arranged axially between the stator and an end shield.

A connection device for connecting at least two electric cables to an electric machine in a vehicle includes a housing and at least two contact elements. At least two openings, each allowing the passage of one of the cables, are located in the housing wall in such a way that only one of the cables that are fed in a direction through the openings in the housing and that continue to run in a straight line in the direction inside the housing makes direct contact with precisely one of the contact elements and can be electrically connected to this contact. All the other cables can be connected to a respective element of the remaining contact elements using a respective conductor bar.

The aim of the invention is to optimize cooling of a rotor using simple means. A rotor is provided, comprising rotor pressure rings () such that at least one of the two rotor pressure rings () is configured in order to enable targeted guiding of the coolant through the axial bores (') in the rotor. In a special embodiment, the rotor pressure ring () can be formed in such a manner that it produces, in several bores (&#x2032;) in the rotor sheet stack (), a flow of coolant in a first direction and in other bores (), a flow of coolant in the other direction. An even, opposite flow cooling can be exclusively obtained by the contour of the rotor pressure ring ().
