1. A motor of an electrical propulsion system, the motor comprising:
an output shaft;
a case enclosing a sealed environment;
a rotor inside the case, the rotor being configured to rotate the output shaft; and
a stator inside the case,
a rotor hub having a first plurality of fins extending from an inner circumferential surface of the rotor hub;
an endplate disposed along an inside surface of the case, the endplate having a second plurality of fins;
wherein the motor comprises a first side and a second side, the first side being closer to the output shaft than the second side, and the rotor is configured to create an air movement with the first plurality of fins and the second plurality of fins inside the sealed environment from the first side towards the second side to provide a cooling effect to one or more components on the second side outside the case.
