The power and speed control parts on the cable reel are borne by the motor, which has unique electrical and mechanical characteristics. The motor has a wide speed regulation range and relatively soft mechanical characteristics. When the load changes, the working speed of the motor also changes accordingly, that is, as the load increases, the speed decreases, and when the load decreases, the speed increases.
Moreover, the motor can operate stably for a long time at any point on its mechanical characteristic curve of torque and speed, ensuring that the cable can obtain appropriate winding speed and tension at the corresponding radius of the reel.
1. The output torque of the cable winding motor is used as the power, and the deceleration part drives the reel to collect the cable.
2. Releasing the output torque of the cable motor as an obstruction force prevents the cable from quickly pulling out the reel, ensuring the synchronization of cable release.
3. During shutdown, the motor is equipped with a disc type normally closed brake to ensure that the cable will not slide off the reel due to gravity when the motor is powered off.
Cable reel is a cable winding device that provides power, control power, or control signals for large mobile devices. It is widely used in heavy machinery equipment such as port gantry cranes, container cranes, ship loaders, tower cranes, and other similar working conditions.
