Abstract: A wire tension control device including a bobbin and a magnetic moment generator is provided. The bobbin is configured to provide a wire. The magnetic moment generator includes a stator and a rotor relatively rotatable with respect to the stator. The rotor is connected to the bobbin. When the bobbin drives the rotor to rotate, the magnetic moment generator generates a tension on the wire.
