A plurality of conductors forming the armature windings are arranged in a superimposed stack, with their end faces aligned and located over the respective commutator strip or lamella. An electrode presses the stack against the lamella, another electrode, preferably liquid cooled, is applied to the lamella and solder, for example in form of a ribbon, placed against the end faces of the conductors forming the stack. Upon application of current, the solder will melt and flow between the commutator lamella and the conductor strips forming the armature winding to simultaneously, in one step, secure together the conductors and the commutator lamella. The method is particularly applicable to forming the armature windings in d-c motors for example in electric-car driving motors. |
