Wheel axial flux yokeless outrunner electric motor providing cables and cooling internally

An electric motor comprising:

• a stator having a main body and a centrally located hollow protrusion extending therefrom, wherein the main body includes a plurality of windings, and wherein the stator includes an inner chamber and an outer chamber;
• power cables and cooling to the stator routed through the outer chamber of the centrally located hollow protrusion;
• a shaft located within the inner chamber of the centrally located hollow protrusion, wherein the inner chamber of the centrally located hollow protrusion is mounted to the shaft via bearings so the shaft can rotate therewithin;
• a first rotor mounted on an exterior of a first side of the centrally located hollow protrusion and having a plurality of magnets facing the stator;
• a second rotor located on an exterior of a second side of the centrally located hollow protrusion and having a plurality of magnets facing the stator, wherein the first rotor and the second rotor are to rotate around the centrally located hollow protrusion when the stator is powered and direction of rotation is based on direction current flows through the coils;
• and
• a hub coupled to the first rotor, wherein the hub includes a plurality of bolts extending therefrom to mount a rim thereto by placing the bolts through aligned holes in the rim, wherein the hub is mounted to the shaft, and wherein the hub rotates with rotation of the first rotor and the rotation of the hub rotates the shaft.

An electric automobile comprising

• a chassis;
• a plurality of wheel assemblies to receive a plurality of rims and an associated plurality of tires mounted to the rims;
• and
• a plurality of electric motors, wherein an electric motor is housed within each of the plurality of wheel assemblies, wherein the electric motors include:
