Magnetic Hysteresis Type Cable Drum

Magnetic hysteresis type cable drum realizes coiling up and spooling off cables through magnetic field transmitting the torque of motor. It adopts magnetic hysteresis plate of difference ring device, it can be in synchronous operation with the mobile electric apparatus to coil up or spool off the cables. It features compact, small structure, invariable of tension, widely used in supply power of the electric apparatus on large-scale mobile devices.
