The stator of an axial gap dynamoelectric machine has at least one substantially planar coil arrays formed by joining two or more sub-coils. Each sub-coil has a serpentine path about the stator perimeter that includes radial segments disposed to generate a Lorenz force with respect to the rotor magnets. The radial segments of the serpentine path joined by alternating inner and outer tangential segments. Each sub-coil starts with a proximal end at an outer tangential segments and a distal end about or within an inner perimeter of the inner tangential segments. Each sub-coil is joined at the distal end with another sub-coil to form the winding coil such that the proximal ends of the sub-coils constitute the two terminals of the planar coil array. This arrangement conveniently places both terminals of the planar coil array at the outer perimeter of the stator while also raising the winding inductance to a level more compatible with conventional motor power supplies.
