DR Italia motorized cable reels are suitable for every application needing to feed electrical power to a moving machinery. The length variations of the electric cable are allowed thanks to the winding/unwinding of the cable on a motorized spool. The electric slipring ensures the electric continuity between the rotating winded cable and the fixed
DR Italia outfits its motorized cable reels with “torque” motors (or “high slip” motors or three phase engings with or without inverter).
The “torque” motor is a special electric motor which can stay blocked in place or forced to counter-rotate for an endless time, providing a constant torque for different speeds of rotation or counterrotation.
Its typical application is just on the cable or hose reels. In fact, these equipments must be able to wind or unwind the cable/hose while maintaining a constant tension on the cable same performances obtained with an asychronous three phase motor managed by inverter, obtaining high malleability and management in real time of the device.
Due to its special application, the “torque” motor can reach high surface temperatures (up to 90 °C), therefore, they are servoventilated by an auxiliary electric fan that generates a constant air flow independent on the rotational speed of the main motor and ensures optimal cooling in any working condition.
