Robust commutator bar anchoring configuration with dove-tailed features

A commutator comprising:

• a base having a periphery, and
• a plurality of commutator bars coupled to the periphery of the base, each commutator bar having a body including a top surface and a bottom surface, a proximal end, a distal end and two opposing sides, the top surface being constructed and arranged to contact brushes of a motor, each commutator bar having at least one pair anchors, each anchor having one end coupled to the body at a location between the proximal and distal ends, a free end of one anchor extending beyond one side of the body and a free end of the other anchor extending beyond the other side of body, the anchors engaging the base, and the commutator bars being arranged about the periphery of the base such that anchors of one commutator bar overlap a domain of an adjacent commutator bar without electrical contact between adjacent commutator bars.
