Abstract
A magnetic core assembly and method of assembling a magnetic core assembly. The core assembly includes laminated magnetic core tightly clamped together by a pair of unitized flanged clamps. Each unitized flanged clamp has a generally flat surface and a peripheral flange. The generally flat surface defines at least one opening for receiving a coil and a number of holes adjacent the opening for receiving assembly hardware. The core is assembled by placing a first one of the two unitized flanged clamps, flange down on a generally horizontal work surface. Alignment pins are placed in one or more of the assembly hardware apertures adjacent the coil opening. The segments of the first core lamination are slidably placed on the alignment pins such that they lie on the flat surface of the first unitized flange clamp. The segments of each remaining core lamination are slidably placed on the alignment pins until the required number of laminations have been installed. After the final lamination is installed, the second of the two unitized flanged clamps is placed on the final core lamination, flat surface down, the alignment pins are removed and assembly hardware is installed and tightened.
