Compact Motor™ Electric Winches - Below Deck

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.

Ease of installation
The Andersen Compact Motor™ electric winch is available in two formats for either Above Deck or Below Deck motor placement. 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 speed 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 trouble shooting 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.

Built-in protection

  • Integrated overload protection - The controller is pre-set to stop the winch if the maximum pull load is exceeded. Operation can resume withina few seconds when the load returns below the limit.
  • Thermal overload protection - The motor is fitted with a thermal cutout that disables the motor in case of overheating; it automatically resets after the temperature returns to normal.

The Power Rib™

Andersen winch drums incorporate the distinctive Power Rib™ which ensures a controlled grip on the line at all times, whether trimming or easing. The highly polished stainless steel surface minimises vertical friction and allows the loaded rope turns to slide easily upward as the drum rotates, without the shuddering and excessive rope wear seen on winches that rely on a rough surface finish for grip.

Stainless steel roller bearings and ball bearings carry the highest drum loads to the centre stem of the winch, minimising efficiency losses due to friction.

The self tailing arm can be rotated through 360 degrees for optimum positioning (40ST and larger). Stainless steel self tailing jaws adjust automatically to suit various rope sizes.
Andersen winches are designed for simple, straightforward installation and maintenance. Servicing is only required every two years or so under normal use.

It’s all about protecting your investment. With ANDERSEN Winches, this protection is guaranteed, as the drum maintains its grip year after year. Keeping wear and tear to a minimum also helps maintain resale value, and our 3-year warranty and instant service in more than 30 countries worldwide amount to a benchmark standard. Low maintenance is a key — and with ANDERSEN Winches, you can take it for granted. Our winches require less maintenance, since all pawls and springs are captive, and the design of the winch allows you to easily strip it down for service and greasing.
