Robust commutator bar anchoring configuration with dove-tailed features

摘要

A commutator bar ( 10 ) includes a body and first and second anchors disposed in spaced relation with each anchor and coupled to a proximal end of the body. A free end of the first anchor ( 13 ) extends in a direction towards the proximal end H of the body, and a free end of the second anchor ( 12 ) extends in a direction towards a distal end ( 0 ) of the body. Third and fourth anchors ( 17 ) and ( 18 ), are disposed in spaced relation and each have one end coupled to a distal end of the body and a free end extending in a direction towards the proximal end of the body. Fifth and sixth anchors ( 15 ) and ( 16 ) each have one end coupled to the body at a location between the proximal and distal ends. A free end of the fifth anchor extends toward one side of the body and a free end of the sixth anchor extends toward the other side of body.
