  • Patent number: 10857609
    Abstract: The present invention provides a non-contact wire array tension control device for controlling a plurality of tension respectively corresponding to a plurality of electrical discharge wires, including delivering spools and electromagnets. The delivering spool has a magnetic end and a wire outputting end, the wire outputting end is coupled with an electrical discharge wire for outputting the electrical discharge wire. A plurality of electromagnets are coupled to the corresponding magnetic end for controlling a spin rate of the corresponding delivering spool, wherein the spin rate of the corresponding delivering spool is controlled by adjusting a magnetic force generated by the electromagnet. Moreover, a magnetic direction of the electromagnet is parallel to an axial direction of the delivering spool. The invention uses the electromagnets to control the magnetic damping force of the delivering spools for simultaneously controlling the tension of the electrical discharge wires by non-contact method.
