ABSTRACT:
An electrical commutator of the type which is formed by bending a strip of conducting material having outwardly extending and spaced apart tangs along one side into a cylindrical sleeve so that the tangs extend outwardly from one axial end of the sleeve. The strip includes at least one, and preferably two, recessed portions in the space between adjacent tangs so that these recessed portions protrude radially inwardly once the strip is formed into the cylindrical sleeve. Anchoring portions on the inner surface of the sleeve, as well as the recessed portions, are then encapsulated in an insulating material, such as phenolic resin. Thereafter, axially extending and circumferentially spaced slots are machined in the outer periphery of the sleeve and these slots extend to a midpoint in the space between adjacent tangs. The machined slots thus separate the conductive strip into circumferentially adjacent commutator segments and the tangs are thereafter bent back to form a connection point for the coil windings of the motor. In practice, the recessed portions of the sleeve between adjacent tangs, together with their encapsulation in the insulating material, serve to reinforce the tangs against outward deflection during rotation of the commutator.
