Electric Winch Components – Parts Diagram 1Motor – In a typical setup, the winch motor runs off your vehicle’s battery. This battery power transfers from the winch motor to the gear train (also known as the drive train), which in turn causes the winch drum to rotate and the steel cable to spool in and out.
Solenoid (also known as Contactor) – The solenoid controls the direction that the drum will rotate. The solenoid receives power from your vehicle’s battery and protects the motor from overheating.
Steel Cable – The steel cable is wrapped around the winch drum and fed through the roller fairlead on the front of the winch. Synthetic rope is an alternative winch cable preferred by some offroaders for its ease of handling and safety.
Roller Fairlead – The fairlead guides the steel cable during the winching process and prevents the cable from getting snagged in moving winch parts. An aluminum fairlead is recommended for use with synthetic cable.
Electric Winch Components – Parts Diagram 2Winch Drum – The winch drum is the spool wrapped with steel cable that rotates during the winching process and winds the cable in or out.
Internal Brake – The brake is the mechanism located inside the winch drum that keeps the load from slipping.
Gear Train (also known as Drive Train) – The gear train converts the power from the winch motor into a pulling force. The gear ratio is a major factor in the line speed.
Freespool Clutch – The freespool clutch allows you to engage or disengage the drum from the gear train. The freespool (disengaged) position allows you to freely spool out the cable by hand. The engaged position allows you to power out the cable.
