Abstract
An axial flux machine (AFM) includes: a rotor assembly configured to rotate about an axis. The rotor assembly includes a first rotor core and second rotor core. Each of the first rotor core and the second rotor core have a plurality of permanent magnets attached thereto, and each of the first rotor core and the second rotor core are spaced apart and parallel to one another and perpendicular to the axis. The AFM also includes a stator assembly having a PCB located between the first rotor core and the second rotor core and parallel thereto. The PCB defines a stator winding configured to generate a magnetic flux in an axial direction through each of the first rotor core and the second rotor core to cause the AFM to generate a torque. A steer-by-wire system includes a handwheel actuator including the AFM coupled to apply a torque to a steering wheel.
