To provide for precise alignment, with easy assembly of stacks of lamellae which form, for example, the armature of a dynamo electric machine, so that the winding slots will be aligned and the lamellae held together by frictional engagement and interlocking engagement of projections and recesses, the recesses are formed by a deformation process in which, first, holes are punched into the lamella elements at each location where the recesses--projections or bulges are to be placed, the holes being smaller than the recesses or projections and located centrally with respect thereto. The edge zones of the holes are then deformed so that the edge zones will have, along a diametrical line, at least approximately part V or roof shape, thereby forming corresponding projections at the other sides of the strip, the angle of the V or roof-shaped surfaces being about 120.degree.. The height of the projection is at least approximately equal to the thickness of any lamella, and the projection is defined by a ridge which extends radially with respect to the longitudinal axis of the opening from both sides of the opening to the outer surface of the projection.

A blank 1 is removed from a strip of material 2 and placed in a die against which a lower punch and an upper punch are operable. In one step, by moving of the lower punch upwardly, shaped to form the pole core or pole piece, and the upper punch against the blank in the die, the pole piece, pole shoes, and outer pole radii at the end portions are formed. If desired, the pole can be perforated and the perforation formed with a thread, and accurately sized in the subsequent cutting and sizing step.

A thermoswitch is physically located on a portion of the current supply connector between the current source and the exciter winding of the starter motor. The portion, constructed as a simple strip with flaps holding the thermostat, influences the temperature-dependent control portion of the thermoswitch according to heating in the armature, field winding, and brushes of the starter motor. The thermoswitch turns OFF the starter system by interrupting current supply to the kick-in starter relay.
