The Jefa linear drive is an extremely strong and compact autopilot drive and much more efficient than existing hydraulic and electro-mechanical autopilot drive units. With a thrust of 400 Kgs on 250 mm centers it's much stronger than a human being (the max. output torque of 100 KgM is equivalent to 100 Kg force on the end of a 1 meter sailboat steering handle extension) and is build for 24 hours per day continuous operation with a total weight of only 6,6 Kgs. The combination of the flat wound (pancake) marine electric motor with the ultra efficient planetary gearbox results in an extremely efficient drive unit to keep the battery for boat charging time to the minimum. The drive can be used on sports boats from 20 to 40 foot l.o.a. (or up to 100 Kgm rudder torque) equipped with a mechanical steering system that can be back driven.
The Jefa linear drive is compatible with all mayor autopilot course marine computers like Raymarine, Simrad, B&G, Silva, Furuno, NKA,etc.
