Disclosed is a Segmented Coil Array ("SCA") for use in rotary electromotive devices, such as motors and generators, which employ multiple coils operating within an axial gap magnetic structure. Individual conductor coils have offset circumferentially extending portions so as to allow interlocking of adjacent coils radially extending portions to form a circular array in which all of the coils' working conductors, which are those in the axial magnetic field, can be oriented in the same plane. This construction allows minimum magnet gap spacing, thus, maximizing the available magnetic flux. The resulting SCA may easily be commuted as a three-phase motor, actuator, or generator. The invention also provides a structure whereby multiple coil arrays and associated magnetic rotors may be alternately stacked in layers so as to further increase the total coil working area within a motor or generator of a given diameter.

[ What is claimed is:] [1.] A segmented coil array for use in rotary electromotive devices with one or two magnet rotors, such as motors and generators, of the type which employ an axial gap magnetic structure, composed of an even multiple of individual wire-wound coils, each coil having substantially the same structure and size and comprising circumferentially extending base portions and radially extending side portions, the radially extending side portions and circumferentially extending base portions joined at their respective ends to define a generally trapezoidal shape: the coil array formed into a ring of partially overlapped alternating coils such that the radially extending side portions of each coil are coplanar.
