No. 1 for clean outboards – Torqeedo.
Superior technology and revolutionary benefits – is
what Torqeedo is dedicated to. And every one of there
products on the market fulfils these requirements. That’s
not just our opinion, but that of independent industry
experts – which is why a range of prizes and awards already
decorate our halls. For the coming season, there are 13
motors from 1 to 15 HP which, by the way, are very quick to
plane. All Torqeedo outboards offer record levels of overall
efficiency; are equipped with integrated on-board computers
including GPS-based range calculation, speed over ground and
battery condition; and are waterproof to IP 67.
The performance of Torqeedo outboards, in relation to their
weight, is as unique as it is excellent – and that applies
across the board from Ultralight and Travel to each of the
Cruise models. In the field of lithium battery technology,
Torqeedo has reached a level with the Power 26-104 that’s currently
unbeatable in terms of intelligence, safety and performance.
Plus, a wide range of well-thought-out accessories – such
as our solar charger 45 W that guarantees independence from
power sockets – round off Torqeedo's range appropriately
Motor technology
» Rare earth magnets
Instead of conventional hexaferrite magnets,
Torqeedo uses rare earth magnets. These may be
considerably more expensive but allow magnetic
field strengths some six times higher than
conventional magnets, thus providing six times
more torque.
In total, the combination of rare
earth magnets and external rotor design
generates about 24 times as much torque (i.e.
2300% more) than a conventional brushed internal
rotor motor with hexaferrite magnets of the same
size. As regards power-to-weight ratio and
torque-to-weight ratio, our motors therefore
continue to be unmatched in the boating sector
and hold world records in all the relevant power
classes.
The outstanding torque of Torqeedo motors is
especially interesting for maritime applications
because it means that efficient high-thrust
propellers can be used.

Electronic commutation
State-of-the-art electric motors now feature
electronic commutation. This means that the
alternating electric field required for the
rotation of the motor is not generated by
sliding contacts, or "brushes", but by
electronic circuits. The main advantages of this
approach are:
-
significantly higher efficiency values,
-
much higher torque values at lower
battery currents,
-
longer service lives, and
-
no maintenance requirements.
By introducing electronically commutated
motors in 2006, Torqeedo not only played a pioneering
role in the maritime sector; Torqeedo Travel and
Cruise models were the first consumer products
in the world to be powered by electronically
commutated motors in the 1 PS class and above.
Nowadays, Torqeedo already use fourth-generation
electronically commutated motors. We both
develop motors, electronic systems and
commutation software ourselves and cooperate on
an exclusive basis with highly reputed motor
producers for the boating segment. As a result,
Torqeedo can always offer the best propulsion solution
for a specific application.

Outrunner Design
Normally, the rotor of an electric motor is
installed internally and surrounded by the
stator. In a design of this type, the magnets
are located inside and the coils used to
generate the electric field are installed
outside. The gap where the torque is generated
is located relatively far inside the motor and
this classical motor design therefore develops
relatively low torque. Torqeedo uses
external rotor motors with the coils positioned
inside. The rotating magnets are installed on a
bell-type structure that rotates externally. The
field where the torque is generated is
positioned as far to the outside of the motor as
possible. As a result, much higher torque is
developed. In addition, the magnet installation
surface on the outside is much larger, allowing
the production of higher kinetic energy, with
additional force in the gap per commutation step
and additional torque
