Abstract

A dynamo electric machine having a wound rotor and a commutator rotatable with the rotor. The conductors of the rotor are in pairs each pair being connected electrically to a respective commutator segment. One end of one conductor of each pair is electrically and physically connected to the other conductor and a projecting portion of said other conductor is electrically connected to the commuator segment.

Claims

1. A dynamo electric machine including a wound rotor and a commutator rotatable with the rotor, the conductors of the rotor being electrically connected in pairs to the segments of the commutator, one end of one conductor of each pair of conductors being electrically and physically connected to the respective commutator segment and the one end of the other conductor of the pair of conductors terminating short of the commutator segment and being electrically and physically connected to said one conductor adjacent the segment, so as to be electrically connected to the segment through said one conductor.

2. A dynamo electric machine as claimed in claim 1 wherein the commutator is a face type commutator.

3. A dynamo electric machine as claimed in claim 1 wherein said other conductor is welded to said one conductor adjacent the end of said one conductor, the end of said one conductor projecting beyond the end of said other conductor.

4. A dynamo electric machine as claimed in claim 1 wherein said one conductor is physically and electrically connected to the respective commutator segment by engaging the end of said one conductor in a slot in said one segment and then hot staking the segment to connect the segment to the conductor.
