Document Type and Number:
Japanese Patent JP7180433
Kind Code:
B2
Abstract:
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.
