An improved dynamo-electric machine such as an electric motor is disclosed including a novel commutator configuration and novel means for aligning a first machine housing relative to a second machine housing. The commutator includes an insulating member having a first and a second end with an outwardly extending member having a plurality of apertures therein extending from the first end of the insulating member. A recess extends partially through the insulating member from the second end of the insulating member. A plurality of electrically conducting members each having a first and a second mounting portion are established about a substantially cylindrical surface of the insulating member with the first mounting portions of the electrically conducting members extending through the apertures in the insulating member. The remaining portions of the first mounting members are bent radially outwardly to provide mounting terminals for connection with the rotor coils. The second mounting portions of the electrically conducting members are bent radially inwardly to engage the recess in the second end of the insulating member to secure the electrically conducting members to the insulating member. The machine includes a permanent magnet having a substantially cylindrical outer surface which is in frictional engagement with the internal diameter of the first machine housing with a portion of the permanent magnet extending from the first machine housing. The second machine housing is aligned relative to the first machine housing by a frictional engagement with the portion of the permanent magnet extending from the first machine housing. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
