1. An axial flux motor comprising:
at least one stator assembly disposed along a motor axis;
a rotor assembly disposed along the motor axis adjacent at least one stator assembly, the rotor assembly comprising a rotor core formed of a rotor hub with a plurality of radially extending, spaced apart fingers defining a magnet pocket between adjacent fingers, the hub, fingers, and pockets together defining a rotor core shape having a rotor core thickness; and
a magnet positioned in a plurality of magnet pockets of the rotor core;
wherein the rotor core is formed of a plurality of individual layers arranged in a stack extending along the motor axis, wherein each of the plurality of individual layers is flat and has the same shape as each other and the rotor core shape.
