Electric machine commutator arrangement - leads end of armature coils of wave winding through slots in direction opposing direction of winding

摘要

The number of armature coils, which are necessary for the interconnection of the parallel armature current branches, corresponds to the number of the commutator segments divided by the number of pole pairs. These coils are arranged at the armature such that, respectively the end (3) of the armature coils in the winding form of a wave winding, is led through the armature slots in the opposing direction of the winding direction of the armature winding. The end (3) of the armature coils is arranged at those commutator segments which mutually have an angular distance of two pole pitches. The winding wire for the interconnection of the parallel armature current branches takes part in forming the torque of the motor and represents a positive part of the armature winding. Brushes are arranged corresp. to the brush arrangement of the wave winding to the commutator. USE/ADVANTAGE - Electrical interconnection of parallel armature current paths of loop winding carried out across commutator, without corresp. bridge plates according to main patent.
