Electric motor vehicle fluid pump

The invention relates to an electric motor vehicle fluid pump (10), in particular to an electric water pump for the supply of a motor vehicle cooling circuit. An electric motor vehicle fluid pump (10) according to the invention comprises a stationary spacer tank (22) fluidly separating a motor rotor (32) and a motor stator (34) of an electric motor (30) driving a pump rotor (16) from one another; and a stationary rotor shaft (14) on which a motor rotor (32) of the electric motor (30), which drives the pump rotor (16), is rotatably mounted, the rotor shaft (14) being mounted indirectly or directly in a force-fitting manner in the spacer tank (22) by means of a conical seat connection (20). This allows for a relatively cost-effective production of the spacer tank (22) and further for a particularly simple and cost-effective installation of the rotor shaft (14). 本发明涉及一种电动的机动车辆流体泵(10)，特别地，本发明涉及一种用于机动车辆冷却循环供应的电动水泵。根据本发明的电动的机动车辆流体泵(10)包括固定的间隔罐(22)，其将驱动泵转子(16)的电动机(30)的电机转子(32)和电机定子(34)相互流体地分离；以及固定的转子轴(14)，电动机(30)的驱动
