Zusammenfassung:An electric generator may include a housing having a housing casing running around in a circumferential direction and front and rear side walls, a radially outer stator rotatably arranged on the housing about an axis of rotation, and a radially inner rotor arranged on the housing in a rotationally fixed manner. The generator may also have an axially outer impeller wheel arranged on an outer side of the front side wall and arranged in a rotationally fixed fashion on the rotor. The generator may further have a primary air inlet having inlet openings formed in the rear side wall, a secondary air inlet having secondary inlet openings formed in the housing casing, an air outlet having a plurality of outlet openings formed in the front side wall, a primary air path from the primary air inlet to the air outlet, and a secondary air path from the secondary air inlet to the air outlet. During operation, the impeller wheel may rotate with the rotor and generate a partial vacuum that generates a primary air flow, which enters the primary air inlet, follows the primary air path, and exits through the air outlet, and a secondary air flow, which enters through the secondary air inlet, follows the secondary air path, and exits through the air outlet.
