Abstract
A reel device may include a stator and a rotor rotationally coupled with the stator. The rotor may include a drum for spooling a cable. The reel device may also include a biasing mechanism configured to rotate the rotor to spool the cable onto the drum, and a magnet connected to one of the stator or the rotor. The other of the stator or the rotor may include a conductive material that interfaces with the magnet when the rotor is turned to slow spooling of the cable onto the drum.
Claims20
A reel device comprising:
- a stator;
- a rotor rotationally coupled with the stator, the rotor comprising a drum for spooling a cable;
- a biasing mechanism configured to rotate the rotor to spool the cable onto the drum;
- a frame fixedly attached to one of the stator or the rotor, the frame including a magnet;
- a conductive material fixedly attached to the other of the stator or the rotor, the conductive material to interface with the magnet when the rotor is turned to generate eddy current and slow spooling of the cable onto the drum, the conductive material including a first conductive material housing on a first side of the frame and a second conductive material housing on a second side of the frame;
- and
- a spacer ring positioned around the frame and between the first conductive material housing and the second conductive material housing for spacing the first conductive material housing and the second conductive material housing apart from one another and from the frame.
