1. A media gap motor for a turbocharger, the media gap motor comprising:
a rotor; and
a stator, surrounding at least a coaxial portion of the rotor, the stator comprising:
multiple stator fins that extend from an inner portion of the stator radially towards the coaxial portion of the rotor in a flow chamber formed between the stator and the coaxial portion of the rotor, wherein the multiple stator fins do not extend as far as the coaxial portion of the rotor, and therefore a gap is formed between an inner end of each of the multiple stator fins and extending circumferentially about the coaxial portion of the rotor, and wherein an internal diameter of each of the multiple stator fins is at least 1.2 times and at most 3 times an external diameter of the coaxial portion of the rotor.
