The motor-driven cable reel is mainly composed of a rotatable cable reel and a driving motor. Under the drive of the motor, the drum can rotate in a specific direction to store and release cables. This type of cable reel is usually equipped with a control system that can adjust the speed and direction of the motor as needed to precisely control the winding and releasing speed of the cable. In addition, some advanced electric cable reels also have tension control function, which can maintain the constant tension of the cable during winding and releasing process, preventing the cable from being damaged due to excessive relaxation or excessive tension. Structurally speaking, the design of cable reels varies to meet the needs of different application scenarios. For example, in some situations where frequent movement and winding of cables are required, cable reels with hydraulic couplings or variable frequency control drive devices can be used to improve their response speed and operational stability.
