Method for producing a component provided with at least one electrically conductive conductor body, wherein the conductor body is surrounded at least in portions, in particular largely, in an integrally bonded and/or interlocking fashion by an injection-molded body formed from an injection-molding material. The method includes receiving the conductor body at least in portions in or on a receiving region of a carrier body, the receiving region delimiting a receiving space. The method also includes encapsulating the carrier body, provided with the conductor body, at least in portions with the injection-molding material to form a component comprising at least the conductor body, the carrier body and the injection-molded body.

A method of manufacturing a coil for a torque sensor includes: holding a bobbin with a jig, the bobbin being formed in a cylindrical shape and provided with first inclined grooves and second inclined grooves on a cylindrical outer peripheral surface of the bobbin, the first inclined grooves being inclined at a preset specified angle with respect to an axial direction of the cylindrical shape, and the second inclined grooves being inclined at the specified angle with respect to the axial direction in a direction opposite to the first inclined grooves; and rotating the bobbin while simultaneously supplying insulated wires from nozzles arranged to surround the bobbin, and driving the nozzles in a direction orthogonal to a rotation direction of the bobbin so as to wind the insulated wires around the bobbin along the first inclined grooves or the second inclined grooves.

An apparatus for winding coils onto a spherical body includes a frame, a feeder spool, a first hemispherical bobbin, a second hemispherical bobbin, a first spring-loaded pin, a second spring-loaded pin, and a motor arrangement. The feeder spool is rotationally mounted on the frame, has first and second wires wound thereon, and is configured to rotate about a first rotational axis. The first and second hemispherical bobbins are rotationally mounted on the frame and configured to rotate about a second rotational axis that is parallel to the first rotational axis. The bobbins are spaced apart from each other to define a wire-feeder gap through which the first and second wires may be fed. The motor arrangement is coupled to the first and second hemispherical bobbins and is configured to cause the first and second hemispherical bobbins to rotate in opposite directions about the second rotational axis.

A winding device includes a winding core configured to take up a wire, wherein the winding core includes an inner winding core configured to be rotated by a rotating part and an outer winding core configured to surround the inner winding core and rotate together with the inner winding core.

A method of manufacturing a high-density coil formed by press working a coil to cope with the manufacture of high-density coils having various cross-sectional shapes. The method includes: a step of setting the coil at a predetermined press working position in a press working machine; and a step of sequential press working the coil, which is set at the predetermined press working position, in a plurality of directions sequentially with a time lag.

A viscous clutch includes an input member, an output member, a working chamber defined between the input member and the output member, a reservoir to hold a supply of a shear fluid, a valve that controls a flow of the shear fluid between the reservoir and the working chamber along a fluid circuit that fluidically connects the reservoir and the working chamber, a bearing, and an electromagnetic coil supported by the bearing. The electromagnetic coil includes a coil housing and a winding that forms multiple turns within an interior volume of the coil housing, wherein the coil housing has a stepped configuration to at least partially accommodate the bearing within a first step. Selective energization of the electromagnetic coil actuates the valve.

A choke includes a single-piece core entirely made of a same material, the single-piece core having two boards and a pillar located between the two boards, a winding space being located among the two boards and the pillar, wherein the pillar has a non-circular and non-rectangular cross section along a direction substantially perpendicular to an axial direction of the pillar, the cross section of the pillar has a first axis and a second axis intersecting with each other at a center of the cross section of the pillar and are substantially perpendicular with each other, the first axis is longer than the second axis, and the cross section of the pillar is substantially symmetrical to both of the first axis and the second axis.

A method of fabricating an electromagnet includes obtaining a first flexible PCB that includes one or more first conductive coiled traces and obtaining a second flexible PCB that includes one or more second conductive coiled traces. The first flexible PCB is bent into a shape having at least one curve or corner. With the first flexible PCB having been bent into the shape, the second flexible PCB is then bent into the shape: the second flexible PCB is positioned adjacent to the first flexible PCB to conform with the first flexible PCB. The second flexible PCB may substantially surround the first flexible PCB. An electrostatic deflector may be disposed concentrically with the first and second flexible PCBs.
