Electromechanical stabilizers are one of the major trends in boating. Their purpose is to provide owners and guests with unparalleled comfort on board. This is achieved through damping, up to almost total cancellation, of the oscillatory movements of the hull while cruising and at anchor.   

WITTENSTEIN offers for this type of solution, extremely silent and compact gearboxes which guarantee maximum comfort for passengers and minimizing overall dimensions. The range embraces planetary gearboxes, hypoid bevel gearboxes and the zero-backlash servo gearbox Galaxie^®, our top-of-the-line solution in terms of power density. Their compact design makes them particularly attractive for both original equipment solutions and retrofits. When the technical solution involves a linear drive, cyber^® force actuators are the ideal solution when compactness and responsiveness are key targets. 
 

If you are searching for a solution which allows you to hybridize a large boat or a yacht to drive fully electric into harbors and to reduce fuel consumption, or if you are trying to upgrade your propulsion system to fully electric, then WITTENSTEN cyber motor offers the development and production of technologically advanced servo motors from frameless to fully housed electric motor solutions. On top of that the high-performance drive electronics as well as complete mechatronic drive systems from WITTENSTEIN cyber motor are providing maximum power density & efficiency. This will allow you to downsize other parts of your electric or hybrid system such as costly battery packs.

Another innovative aspect that goes hand in hand with the introduction of electric motors is the concept of reducing transmission noise. The bevel gears normally used in internal combustion engines are not the optimum choice for electric motors. WITTENSTEIN designs and manufactures ground Gleason bevel gears which ensure quiet operation through optimization of the microgeometry and enhance the benefits of electric propulsion. 
In addition, coaxial gearboxes can also be designed for off-board propulsion units.

Foils, interceptors or any aerodynamic additions which are intended to regulate the trim of vessels while reducing fuel consumption are driven by servo units or actuators. WITTENSTEIN planetary gearboxes as well as cyber^® force linear actuators take up less space and ensure high dynamics and reliable operation.

Thrusters are propellers that help to steer a vessel transversely during docking or mooring.  In their most common form, they are located below the waterline at the bow to push the bow of the vessel sideways. They are usually driven by an electric motor while the transmission is provided by a bevel gear.  

Taking advantage of the experience and know-how gained in the production of series bevel gearboxes, WITTENSTEIN designs and manufactures Gleason bevel gears according to the customer´s specifications, either with lapped or ground finishing, to ensure noiselessness compactness, and reliability.

For every need of electrification on modern yachts such as gangways, roofs, sunshields, door and window systems, automated furniture, balconies and garage opening solutions, cranes or boarding ladders, WITTENSTEIN offers small servo drive system from the cyber^® kit line small series and highly integrated motor gearboxes that make it possible to replace hydraulic actuators for greater simplicity, quiet operation, sustainability and eliminating oil leaks from hydraulic systems.

Saving energy, sustainability and on-board comfort are gradually becoming more and more important for fishing vessels too. Replacing hydraulic systems with electric or electromechanics solutions make it possible to reduce fuel consumption and noise on board. 
One example application is the electric hauling system. An Actuator from the TPM⁺ / premo^® series can provide responsive and accurate tension control of the line during hauling despite the oscillations of the boat, thus reducing fish losses and line breakage.

For rotation and elevation handling of any type of radar or antenna, WITTENSTEIN offers compact servo rotary actuators. Their high uniformity of rotation, torsional rigidity and precision also allows direct connection, without intermediate mechanical transmission parts.
