Unique systems, methods, techniques and apparatuses of exciterless synchronous machines are disclosed. One exemplary embodiment is a fractional slot synchronous machine comprising a rotor including a first pole pair including a first pole including a first plurality of slots having a first center point and arranged on a first outer surface in a slot pattern; a second pole pair including a second pole including a second plurality of slots having a second center point and arranged on a second outer surface in the slot pattern; energy harvest windings arranged in a winding pattern within a portion of the first plurality of slots and arranged in the same winding pattern within a portion of the second plurality of slots, the energy harvest winding being structured to receive a harmonic power from the stator; and a rectifier structured to receive the harmonic power from the energy harvest winding.
