MINITRON the Ultimate in Wire Constant Tension Feeding.

MINITRON is one of the latest results from BTSR INTERNATIONAL, a worldwide leading company in the design of high tech solutions and innovation develpment in a wide variety of industrial sectors.   

MINITRON represents a revolutionary new generation Wire Constant Tension Feeding device, unique in terms of functionality and performance, capable of adjusting with utmost accuracy the tension of the wired in motor and coil winding processes.

An innovative Solution based on the BTSR Dual-Drive Feeding System, Tension Profiler Function and Double Loop Control System bringing new and unique measurable benefits in terms of TOP Quality Control and Production Efficiency in coil winding processes.


  • TOP Quality Standards Goal is ensured by the highest coil winding quality and repeatability, thanks to BTSR ‘Double Closed Loop’ Technology guaranteeing the most accurate and precise wire tension control.
  • TOP Versatility is guaranteed by Fully programmable parameters according to the wire requirements and possibility to dynamically modify the wire control tension according to the operating stage (‘Tension Profiler’ Function).
  • TOP Process Production Efficiency is enhanced by dramatic reduction of wire breakages
  • TOP Productivity is guaranteed by the capability to work at the maximum possible process speed.
  • Minimized Labour Costs is possible thanks to the user-friendly programming options.
  • A wide application range is possible thanks to the wide wire tension and diameter range of MINITRON
  • Centralized programming and monitoring is possible thanks to MATRIX TOUCH COIL controller which will allow to program and control MINITRON units and monitoring the whole process production status also in graphical form.
