Abstract
A commutator assembly for a motor has a recessed portion formed to each commutator segment so that coils, which are pressed and deformed by bending the hooks of commutator segments, can be accommodated in the recessed portion. With this arrangement, the commutator assembly can improve the reliability of electric connection of the hook of the commutator segments with a conductive wire.
