<p>The present invention provides in a reciprocating electric motor of the type in which a magnetically permeable armature is disposed to axially reciprocate within an air-gap of a fixed electromagnetic circuit, the method of forming a magnetic core for said fixed electromagnetic circuit comprising the steps of spirally winding first and second inner convoluted loops of magnetic strip material, placing said first and second inner loops on a common plane perpendicular to the axis of reciprocation of said armature such that adjacent sides of said inner loops are in flatwise abutment on a plane perpendicular to said common plane, clamping said abutting inner loops tightly together and forming said air-gap in the area of abutment of said inner loops, the central axis of said air-gap being coaxial with said axis of reciprocation and perpendicular to said common plane.</p> |
