The efficiency of a ship propulsion
system depends on the shaft speed
and the correct selection of the used
propeller. Because of the superior
torque curve of an electric motor
compared to a gasoline engine,
larger 2 - and 3-blade propeller can
be used at low shaft speed. Because
of this principle, a very high
thrust is developed even with small
drives. Both the AC and the GP
engine are available with either a
fixed or folding propeller. Kräutler
AC drives are also completely
maintenance-free
