During the block stage, the motor can be either not supplied (long block), or being supplied along the winding direction (short block) allowing the system to slip.
During the unwinding phase, the motor is supplied along the cable winding direction, and the cable is unwound trough traction by the operating machine.3– Winding
Phase3– Winding Phase
During the winding phase, the motor is supplied along winding.The torque motor can operate on a continuous basis (100%) without being damaged, since it can resist temperatures of 100°C and above.

MCR MOTOR CABLE REEL
Motor Driven Cable Reel is specially designed and manufactured for mobile feeding power systems. The feeding is realized by low voltage electrical cables.
The mobile systems are generally overhead cranes or translating working machines, used in all kinds of environment, such as ports, steelworks, constructions, lift and transports plants. This means that this machine has always to be integrated with other machines as a complement. For this reason it is normally controlled by the machine it is integrated with; rarely, it is equipped with an independent control panel .
