The power part and speed regulation part on the cable reels
are borne by the motor, which has unique electrical and mechanical characteristics. The motor has wide speed regulation range and soft mechanical characteristics. When the load changes, the working speed of the motor also changes accordingly, that is, the load increases, the speed decreases, the load decreases and the speed increases. Moreover, the motor can run stably for a long time at any point on the mechanical characteristic curve of torque and speed, so it can ensure that the cable can obtain appropriate winding speed and tension on the corresponding radius of the reel.
The output torque of the cable winding motor is used as the power to drive the reel to collect the cable through the deceleration part.
2. (cable reels)Release the output torque of the cable motor as the blocking force to prevent the cable from rapidly opening the reel and ensure the synchronization of cable laying.
3. (cable reels)
During shutdown, the long-term locked rotor motor is equipped with disc normally closed brake, which can ensure that the cable will not slip from the reel due to gravity when the motor is powered off
