An electric motor or generator (10) comprising a housing (12) which is substantially cup-shaped and having an end wall (26) and an annular outer wall (28), a fluid flow passage (30) being formed through the end wall, and a fluid flow passage (32) being formed through the outer wall; an inlet (34) connecting with one (30) of the flow passages; an outlet (36) connecting with the other (32) of the flow passages; a stator (14) fixedly secured within the housing; a shaft (16) having a longitudinal axis (A), extending into the housing, and rotatable about the longitudinal axis relative to the housing and the stator; and a rotor coil (18) mounted on the shaft and positioned within the stator; wherein the flow passages are integrally formed in the end wall and the outer wall of the housing and are connected to define a single flow path through the housing between the inlet and the outlet. Improved cooling with reduced risk of blockage. <IMAGE> <IMAGE> |
