How does the tension control system control the torque of the magnetic powder clutch?
The manual tension controller of the Tianji Brand adjusts the excitation current of the magnetic powder clutch or the magnetic powder brake in stages according to the change of the receiving or discharging diameter, thereby obtaining the torque of one arrival.
The most common set of tension control systems can be divided into discharge group, feeding group and receiving group.The tension of the discharge is determined by the manufacturing torque of the magnetic powder brake provided in the discharge group. In order to maintain the fixed tension, the manufacturing torque must be reduced according to the reduction of coil diameter.The feeding group uses a geared motor to feed the long-size material from the left to the right, and determines the conveying speed according to the speed of the speed-reducing motor, but the tension is irrelevant. However, when the tension is large, the output force of the motor is Become bigger.The receiving speed of the receiving group needs to be faster than the line speed to determine the input speed of the magnetic powder clutch.
Since the line speed is determined by the rotor reel, the magnetic powder clutch will slip.The tension of the receiving group is determined by the torque transmitted by the magnetic powder clutch. In order to maintain a constant tension, it is necessary to increase or decrease the transmission torque according to the size of the winding diameter.
