Coil winding machine parts Magnetic Tensioner(tension control) is used on coil winding machine by using permanent magnet, tension is generated to the damp wheel. The non-contact mechanism design provides stable, consistence and precision tension to the wire. Excellence for both high and normal speed winding. Coil winding machine parts magnetic tensioner.
