Abstract:
A combined armature and commutator assembly for an electric motor, which comprises:a) an armature core having armature windings positioned around said armature core; andb) a commutator adapted for contact by electrically conductive brushes of the motor for conducting electrical current to said armature windings, said commutator having at least two opposed annular shaped surface portions, each having an annular array of commutator segments in concentric relation, a first inner array being associated with a lower motor speed and a second outer array being associated with a higher motor speed, said second outer array including at least twice the number of commutator segments as said inner array, said commutator being attached directly to said armature core to rotatably support said armature core on the rotor shaft of the electric motor.
