Jefa 200 Nm autopilot drive unit
The Jefa transmission drive is one of the most compact autopilot drives in the world. It's as strong as a human being (the max. output torque of 200 Nm is equivalent to 40 Kg on the rim of a 1 meter wheel) and is build for 24 hours per day continuous operation with a total weight of only 6 Kgs. The combination of the specially designed electric motor with the ultra efficient 3 stage planetary gearbox results in an extremely efficient drive unit to keep the battery charging time to the minimum. The drive can be used on boats from 30 to 60 foot (or with a rudder torque up to 525 KgM) equipped with a Jefa transmission steering system and is available in three different speeds: 3.5, 6, and 8 revolutions per minute. The speed choice depends on the reduction of the steering system.
