Andersen Compact Motor™ electric winches allow you to hoist and trim sails at the push of a button regardless of physical strength, so any crew member can easily and safely trim sails and control lines.
All Compact Motor™ Above Deck winches are supplied with 1 set of 41mm (1 5/8”) terminal extensions. Additional terminal extension kits are available to order to suit longer “U” dimensions.
Ease of installation
The Andersen Compact Motor™ electric winch is available in two formats for either Above Deck or Below Deck motor placement. The motor gearbox and controller are integrated into one compact unit with no extra control box necessary. Simplified electrical installation requires just the connection of positive and negative power cables to the motor terminals and the connection of the push button using the included output cable.
Efficient, variable speed
The Andersen Compact Motor™ is a brushless DC motor carefully matched to a low-profile planetary gearbox which requires less space for installation and draws considerably less current than traditional motor/gearbox configurations. Available in 12-volt and 24-volt models, Compact Motor™ electric winches operate at variable speeds in proportion to the pressure applied to the push button, for smooth and quiet operation.
Illuminated "intelligent" push button
Compact Motor™ winches are supplied with a push button with integrated LED which illuminates when power to the winch system is on. The push button incorporates a hinged safety cover to prevent inadvertent winch operation and is water resistant, rated to IP67. The push button also acts with the controller to flash status codes that assist with troubleshooting in the event of overload or where other system protection intervention occurs. A cable for connection of the push button is included for convenient installation.

Mounting of an Above Deck Compact Motor™ winch on a vertical surface is not recommended, as it increases exposure to potential problems of excessive moisture and water ingress which could lead to damage not covered by warranty. The motor/gearbox unit of any above-deck compact motor electric winch is more exposed to the elements than a below-deck installation which keeps the motor unit and gearbox more protected. It is important to take reasonable precautions to protect the unit from unnecessary exposure and carry out regular seasonal maintenance including the lubrification of the motor shaft seal. On commercial and military vessels, it is common to see exposed equipment with electric motors and gearboxes fitted with covers when not in use or to protect them from heavy spray, etc. Equipment on yachts deserves the same proper care.
