An improved airgap armature for use in brushless rotary electrical machines is constructed with multiple phase windings comprised of wires that are wound onto and bonded to a supporting form constructed from nonmagnetic and electrically nonconductive material. The form has two ends, each with features for holding end turns of the multiple phase windings. The multiple phase windings have active lengths and end turns, with the active lengths being located on one side of the form and the end turns located on the opposite side of the form. The active lengths, which are located in the armature airgap of the electrical machine, lie flat against the form for minimal thickness, and the airgap armature can achieve maximum winding density. The form provides an easy method for winding as well as increased structural integrity in the final armature to enable it to transfer torque between the rotor and stationary housing.
