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.

Dependent claims

A case for an electric motor, the case comprising:

a case body including:
an inner case, the inner case having a stator accommodating space located therein, the stator accommodating space extending in an axial direction of the inner case;
an outer case disposed outwardly of the inner case, the outer case being spaced apart from the inner case to form a cooling fluid flow path between the inner case and the outer case;
and
a circuit component mounting portion provided on the outer case;
a first case cover coupled to a first end portion of the case body, and a second case cover coupled to a second end portion of the case body, the first case cover and the second case cover being configured to cover the stator accommodating space, the first case cover and the second case cover being connected with the cooling fluid flow path;
and
a circuit component provided on the circuit component mounting portion,
whereby the circuit component is cooled by cooling fluid provided within the cooling fluid flow path.
