A conductor assembly and method for making an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one series of embodiments the assembly comprises a spiral configuration, positioned along paths in a series of concentric cylindrical planes, with a continuous series of connected turns, each turn including a first arc, a second arc and first and second straight segments connected to one another by the first arc. Each of the first and second straight segments in a turn is spaced apart from an adjacent straight segment in an adjoining turn.

According to an embodiment, a scanning coil includes a bobbin, a conducting wire, and a resin for fixing the conducting wire. The bobbin includes a main body having a truncated conical cylindrical outer shape in an integrated or assembled state and made of an electrically insulating material, a wire-laying path which is formed in the main body and in which a conducting wire is installed, and a plurality of holding parts formed along the wire-laying path on an inner peripheral surface side of the main body and with axial intervals therebetween.

An MRIS gradient coil sub-assembly comprising a first coil layer comprising a first conducting coil portion, a second coil layer comprising a second conductive coil portion electrically connected with the first conductive coil portion so that the first and second conductive coil portions act together as one coil, and a B-stage material consolidation layer sandwiched between the first and second coil layers. A method including laminating a first punched sheet metal conductive saddle coil portion and a second punched sheet metal conductive saddle coil portion together by bonding the first and second punched sheet metal conductive saddle coil portions on opposing sides of a B-stage material insulation layer, and electrically connecting the first punched sheet metal conductive saddle coil portion to the second punched sheet metal conductive saddle coil portion in parallel so that the first and second conductive saddle coil portions act together as one saddle coil.

Systems and methods include using a magnetic core winder to install a powerline-mounted device with a non-gapped magnetic core, therefore reducing the weight of the powerline-mounted device while still harvesting equal or more power than a large cross-sectional and gapped magnetic cores. In particular, the methods include installing bobbin(s) and a core housing on a powerline and winding strip/ribbon core material onto the core housing. The bobbins may be wound axially opposed to on a toroid winder, which improves the accuracy of turns count of the magnetic core. The improved accuracy of turns count may increase the accuracy and/or tolerance of magnetic component(s) of the powerline-mounted device.

The invention relates to saddle coil winding apparatus, methods of manufacturing saddle coils, and saddle coils produced using the winding apparatus and/or manufacturing methods. The saddle coil winding apparatus and methods of manufacturing beneficially reduce or eliminate the stretching of electrical wires, and do not cause the electrical wires to slide past each other. The saddle coils produced using the winding apparatus and/or manufacturing methods may have electrical leads provided on the outside of the coil.
