A dual stator axial gap DC brushless machine is provided with first and second stators having equal pole counts, a given pole arc, and a given slot arc. A rotor is disposed between the first and second stators, having a pole count greater than the first and second stators. The pole count ratio between each stator and the rotor is six to eight. The second stator has a given degree of angular displacement relative to the first stator less than, 3/4, 1/2 or 1/2 the pole arc of the stators, but not less than the slot arc of the stators. Where the first and second stators each have a pole count of 18 and the rotor has a pole count of 24, the stator pole arc is 20 degrees, the rotor pole arc is 15 degrees, and the given degree of angular displacement is less than 20 degrees, 15 degrees, 10 degrees, or 5 degrees.
