ABSTRACT:
A wire tensioner, for feeding wire from a wire source to a wire handling machine such as a coil winding machine, comprising a tension pulley coupled with an output shaft of a motor via a clutch such as an electromagnetic powder clutch with a variable torque transmission capability. Wire is passed around the tension pulley which is turned by the motor in the direction opposite to the feeding direction of the wire. By controlling the torque transmission ratio of the clutch, the tension of the wire is controlled with a fast response. This tensioner can be advantageously used for a motor coil winding machine to removing any slacking in the coil wire and improving the wire density of the motor coils.
