Abstract: A high-torque low-inertia armature for use with an electric motor wherein the armature winding is formed of aluminum conductors, and wherein a copper commutation band is formed on selected aluminum conductors in a manner to mechanically lock each commutator segment to its aluminum conductor, the locking structure being constructed and arranged to continue to function as the motor brush wears away to the top surface of the aluminum conductor.
