Abstract

A fluid cooled motor (1) includes a stator (2), a rotor (4) disposed in the stator (2) rotatably in a circumferential direction, and a stator coil (22) wound on the stator (2), the stator coil (22) having coil ends (23a,23b) extending in an axial direction perpendicular to the circumferential direction. The rotor (4) has a rotor core (3) and annular end plates (10a,10b) fixed to axial ends of the rotor core (3), the annular end plates (10a,10b) opposing to the coil ends (23a,23b) of the stator coil (22) and being rotatable with the rotor (4) in the circumferential direction. Each of the end plates (10a,10b) includes a plurality of flow passages to guide a cooling fluid from an inlet to an outlet thereof in a radially outward direction. Each of the flow passages extends from the inlet to the outlet, and inclines or curves to a direction opposite to a rotation direction of the rotor (4) with respect to a radial direction.
