Abstract

The invention provides a pump system and a manufacturing method thereof, and further provides a vehicle. The pump system includes a housing having a pump for pumping a liquid and an electric motor therein. A stator of an electric motor has a stack of laminations mounted between a first motor housing part and a second motor housing part. The second motor housing portion is attached to the stack of laminations, and the first motor housing portion comprises an integrated inner frame shaped to receive the stack of laminations and components of the stator therein, the first motor housing portion forming part of a motor housing for the electric motor. The integrated inner frame and the first motor housing portion may be formed as a unitary continuous part, such as molded from plastic.
