Abstract

An electric motor (1) comprising a rotor (2) rotatably arranged about a central axis (A) of the electric motor (1) and a stator (3) coaxial with the rotor (2). The stator (3) comprises a stator core (4) having a radially outer surface (10) comprising a plurality of ribs (8, 8') distributed circumferentially and extending longitudinally between axial ends (4a, 4b) of the stator core (4). The electric motor (1) further comprises a housing (12) arranged radially outside the stator (3) such that a substantially annular gap (14) is formed between the outer surface (10) of the stator core (4) and an inner wall of the housing (12). Moreover, the electric motor (1) comprises a cooling system (20) configured to create a circumferential flow (F) of a cooling liquid in the substantially annular gap (14). A vehicle (100) comprising the electric motor (1) is also disclosed.
