Abstract
A case for an electric motor includes a case body provided with an inner case and an outer case together forming a cooling fluid flow path penetratingly formed in an axial direction of the case body, and a circuit component mounting portion protruding from an outer surface of the outer case to mount a circuit component such that the circuit component is cooled by cooling fluid. Case covers are coupled to both end portions of the case body so that the electric motor and the circuit component can be simultaneously cooled by the single cooling fluid flow path. In this way, a separate circuit component case for mounting the circuit component can be excluded, thereby reducing a size and weight of the case.
