Abstract:
1. A motor comprising: a stator core having an exposed outer surface and defining a cavity having a first open end and a second open end; a rotor core positioned at least partially within the stator core; a quantity of coolant, at least a portion of which is positioned between the rotor core and the stator core; a first encasement member completely enveloping the entire stator core to inhibit direct contact between the stator core and the coolant, the first encasement member covering the first open end and being in direct contact with substantially the entire exposed outer surface of the stator core; a second encasement member coupled to the rotor core to inhibit direct contact between the rotor core and the coolant; and a cap coupled to the first encasement such that the cap substantially covers the second open end to substantially seal the quantity of coolant within the first encasement member.
