Pre tension device tension controller of magnetic damper safety belt tightening device? Electronic tension device Characteristics: the core tension generating component adopts the electromagnetic hysteresis brake or function is a bit poor magnetic powder type brake, after a low voltage current conditioning, tension stability, LED display. (hysteresis brake rotor and stator magnetic pole is composed of two parts. The rotor is composed of magnetic hysteresis data special made, a certain gap stator magnetic pole, a rolling rotor in the space. When the coil is energized, the occurrence of magnetic gap, make rotor hysteresis effect. When the hysteresis of rotor under the action of external force to overcome the hysteresis force rolling, occurrence of rated torque. Torque only and excitation current size, has nothing to do with speed, realize non torque transmission touch.) Magnetic tension device Characteristics: the magnetic tension device is the result of magnetic torque generating damping, no mechanical conflict, so long-term stable tension can occur, and the precision can be useful to ensure appropriate precision, the general requirements of the use of the product, low price! Economic type! Working principle: the use of non touch type magnetic torque supply torque. Advantages: the magnetic tension device is the result of magnetic torque generating damping, no mechanical conflict, so long-term stable tension can occur, and the precision can be useful Guarantee. The MTA class will supply two section tension, winding time bound feet need to meet. Defect: because the tension device structure itself limits, in the winding set tension can only from tension adjustable to high tension, if the high tension adjustable tension must be cut into small, small and then cut to the required tension in winding state in the parking state, the preferred Jincheng industrial!
