Methods, systems, and apparatuses for passive end-turn cooling for an electric motor using gravity

A vehicle apparatus comprising:

• a gravity drive to distribute coolant oil flow from a nozzle over an exterior surface of an electric motor;
• a connector coupled to the nozzle that enables the nozzle to sway in response to external forces encountered by a vehicle operation and to distribute coolant oil over the exterior surface of the electric motor;
• and
• a counterweight that is coupled to the nozzle that provides a countermeasure to the external forces encountered by the vehicle operation to cause the nozzle to sway in a manner that enables the coolant oil to be distributed evenly across the exterior surface of the electric motor.

A method to distribute coolant oil evenly across an exterior surface of an electric motor of an apparatus, comprising:

• directing a flow of coolant oil by a nozzle using a gravity drive over the exterior surface of the electric motor;
• coupling the nozzle to a rubber connector that enables the nozzle to sway in response to external forces encountered by a movement of the apparatus and to distribute coolant oil over the exterior surface of the electric motor wherein the external forces are resultant from gradients and apparatus accelerations;
• and
• coupling a counterweight to the nozzle to provide a countermeasure to the external forces to cause the nozzle to sway in a manner that enables the coolant oil to be distributed evenly across the exterior surface of the electric motor.
