An electrical flux conducting rotor is formed with a stack of sheet metal blanks laminated together, with the blanks extending perpendicular to the axis of rotation. The blanks have similar outline shapes disposed in alignment in the stack. The outline shape of each blank has a symmetry such that any blank in the stack is capable of being stacked in outline alignment with any other blank when displaced in such stacked relation angularly about the axis of rotation of said rotor a plurality of equal angular divisions of 360 DEG . Each blank has a predetermined orientation based upon being similarly blanked from the same metal sheet. The blanks of the stack are arranged preferably in one group which contains four successive blank sections, each blank section containing an equal number of blanks. The blanks of the outer two blank sections are displaced angularly 180 DEG with respect to the predetermined orientation relative to the inner two blank sections, so as to statically and dynamically balance the orientation of the blanks of the blank sections about the axis of rotation of the rotor.
