Abstract
To separate cooling fluid, such as water, from the commutator space of a dynamo electric machine, typically a motor for battery-energized vehicle, a disc (18) of insulating material is fitted on the commutator (5), terminating at its end portion in a slinger structure (20, 21) which is positioned in intergaging relation with respect to a labyrinth (21, 22) secured to the housing of the machine. Cooling fluid is admitted to the space within which all the electrical windings (3, 9) are located, so that the cooling fluid, for example water, can fill the space (28) of the housing, while being separated from the space (57) within which the commutator (5) and commutator brush holder (7) is located.
