ABSTRACT:
A method for assembling a high current commutator and winding to form an armature includes positioning end portions of pairs of conductors against a connection portion of a segment on the commutator. A support member is engaged with the connection portion while a connection member, such as an electrode or sonotrode, applies energy to fuse together the stack formed by the connection portion and the conductor ends together. The connection member and the support member are then disengaged from the stack after the stack is fused together. The apparatus for assembling the armature includes connection member and the support member. The support member confines the securing energies to the stack thus allowing the commutator segments, connection portions and a core of the commutator to be made lighter.
