Motor-driven fairlead to aid in spooling or unspooling a line from a winch
A fairlead for use with a winch is disclosed. The fairlead includes: a device for detecting a speed at which a line is being spooled or unspooled from the winch, a first and second roller adapted to aid in spooling or unspooling a line, a fairlead motor for driving at least the first roller, and a controller connected to the fairlead motor. The controller is in communication with the device for detecting the speed. The controller is configured to direct the fairlead motor to drive at least the first roller at a speed that maintains tension on the line as it is unspooling or spooling. Alternatively, the device measures current drawn by the fairlead motor and the controller directs the fairlead motor to drive the rollers at a speed that maintains a target current draw.
1. A fairlead for use with a winch comprising:
a sensor for detecting a speed at which a line, adapted to transmit a tensile load, is being spooled or unspooled from the winch
a first and second roller adapted to aid in spooling or unspooling a line;
a fairlead motor and gears for rotating the first and second rollers;
a controller connected to the fairlead motor, and in communication with the sensor for detecting the speed; and
wherein, the controller is configured to direct the fairlead motor to drive both the first roller and the second roller so that each of the first roller and the second roller are rotated by the fairlead motor to pull the line out when the line is being unspooled, and each of the first roller and the second roller are rotated by the fairlead motor to push the line in when the line is being spooled, and the line is pushed or pulled at a speed that maintains tension on the line as it is unspooling or spooling.
2. The invention of claim 1 , wherein the sensor is a tachometer.
3. The invention of claim 1 , wherein the fairlead is integrated into a winch.

5. The invention of claim 4 , wherein the speed at which the motor is driving the roller is configured to be adjusted by a user.
6. The invention of claim 1 , wherein the gears are configured so that the motor will drive the first and second rollers in opposite directions to ensure that each of the first roller and the second roller pull the line out when the line is being unspooled, and each of the first roller and the second roller will push the line in when the line is being spooled.
7. A fairlead for use with a winch comprising:
a first and second roller adapted to aid in spooling or unspooling a line, adapted to transmit a tensile load;
a fairlead motor and gears for driving the first and second rollers;
a sensor to measure the current drawn by the fairlead motor,
a controller connected to the fairlead motor, and in communication with the sensor;
wherein, the controller is configured to direct the fairlead motor to drive both the first roller and the second roller so that each of the first roller and the second roller are rotated by the fairlead motor to pull the line out when the line is being unspooled, and each of the first roller and the second roller are rotated by the fairlead motor to push the line in when the line is being spooled, and the line is pushed or pulled so that the fairlead motor maintains a target current draw.
8. The invention of claim 7 , wherein the sensor is a current sensor.
9. The invention of claim 7 , wherein the controller directs the fairlead motor to decrease the speed at which the rollers rotate as the line is unspooled from a winch drum.
10. The invention of claim 7 , wherein the controller directs the fairlead motor to increase the speed at which the rollers rotate as the line is spooled onto a winch drum.
11. The invention of claim 7 , wherein the controller is adapted to communicate with and receive commands from a remote-control device.
12. The invention of claim 11 , the target current draw is configured to be adjusted by a user with the remote-control device.
13. The invention of claim 7 , wherein the gears are configured so that the motor will drive the first and second rollers in opposite directions to ensure that each of the first roller and the second roller pull the line out when the line is being unspooled, and each of the first roller and the second roller will push the line in when the line is being spooled.
14. A winch comprising:
