ABSTRACT:
A commutator is disclosed which is adapted to be mounted on a rotor shaft of an electric motor for cooperation with electrical contacts of the motor, the commutator being capable of accommodating two speeds of the motor. The commutator includes a support member formed of electrically insulating material and having a central opening for receiving the rotor shaft, the support member having a surface portion for attachment of commutator segments. A first plurality of circumferentially spaced, electrically conductive commutator segments are attached to the surface portion of the support member and are arranged in a generally circular array and wired to the armature to accommodate at least a first speed of the motor. A second plurality of circumferentially spaced, electrically conductive commutator segments are attached to the surface portion of the support member and are positioned radially outward of the first plurality of spaced commutator segments. The second plurality of segments are also arranged in a generally circular array and wired to the armature to accommodate the second speed of the motor. Hook members are provided to connect the first and second pluralities of commutator segments to the armature windings of the motor. The hook members preferably extend through apertures in the support member. A two speed motor incorporating the commutator is also disclosed. The commutator may also be arranged to be incorporated into motors having more than two speeds.
