Features: core tension produce parts using magnetic hysteresis brake type magnetic powder brake is a bit poor, or performance by low voltage current adjustment, stable tension, LED display.(hysteresis brake consists of rotor and stator poles of two parts. The rotor is made from special material of hysteresis, there is a certain gap in the stator poles, the rotor rotation in the gap. When the coil current, magnetic field is formed in clearance, make the rotor produces hysteresis effect. When the action of external force hysteresis rotor overcome force hysteresis turns, produce the rated torque. Torque is only related to the exciting current size, has nothing to do with speed, realize the non-contact torque transmission.)
Features: magnetic tension control is through the magnetic damping torque, no mechanical friction, so can produce stable tension for a long time, and can effectively guarantee accuracy, suitable for precision generally the use of products, price is cheap, affordable.Working principle: by using non-contact magnetic torque to provide torque.Advantages: magnetic tension control is through the magnetic damping torque, no mechanical friction, so can produce stable tension for a long time, and the precision can be effectivelyGuarantee.The MTA class provides two tension, meet the needs of the coiling time bound feet.Disadvantages: due to the structure limit tensioner, winding large setting when tension only from tension to tension, if you want to turn big tension into small tension, must be in the state by small parking and then cut to the required tension in winding state.
