            ACTION: 
               
              This clutch is a magnetic close type which engages on when coil 
              is excited. The field is excited then and magnetizes rotor to engage 
              for facing with friction force. When the current is interrupted, 
              magnetizing is disapeared and armature returns back quickly with 
              release spring and then clutch is rereased. Clutch torque can be 
              easely controlled by adjusting current. |
