Zusammenfassung:	Disclosed in the present invention is a fluid pump (10) and, especially, an oil pump, for supplying a clutch actuator, a gearbox actuator, a lubrication system and/or cooling system of a drive train including an electric drive unit having a stator (22) and a rotor (24). According to the present invention, the rotor (24) is arranged inside the stator (22), and an inner wall (30) defining a stator chamber (22a) radially inwardly includes at least one wall portion (30a) that engages an assigned radial depression portion (22c) of the stator (22) existing between two circumferentially adjacent stator segments (22b). Furthermore, a method for manufacturing the fluid pump (10) is proposed. 고정자(22) 및 회전자(24)를 갖는 전기 구동 유닛(18)을 갖는, 구동 트레인의 클러치 액추에이터, 기어박스 액추에이터, 윤활 시스템 및/또는 냉각 시스템에 공급하기 위한 유체 펌프(10) 특히, 오일 펌프가 설명된다. 회전자(24)는 고정자(22) 내부에 배열되고, 고정자 챔버(22a)를 방사상으로 내측으로 한정하는 내벽(30)은 두 개의 원주 방향으로 인접한 고정자 세그먼트들(22b) 사이에 존재하는 고정자(22)의 할당된 방사상 함몰부(22c)에 맞물리는 적어도 하나의 벽 부분(30a)을 갖는다. 나아가, 유체 펌프(10)를 제조하는 방법이 제안된다.
