Electrical Drive Engineering
The
electric
direct
drive
motor
solution
with
3
separate
controllers
and
‚intelligent'
startup
software
provides
that
different
kinds
of
energy
storages
can
be
used.
For
example
you
can
select
for
each
motor
segment
not
only
different
battery
types
even
more
than
this:
solar
cells,
fuel
cells
or
electric
power
generator.
In
this
way
there
is
great
variety
of
energy
sources
possible.
We
are
favoring
for
future
technology
a
combination
of
high
power
LiIon
batteries
in
combination
with
reformer
fuel
cell
techniques
consuming
ethanol.
Our
two
blade
folding
propeller
designed
by Jürgen Arnold (scientist at the DLR
Göttingen)
and
produced
by
‚HELIX'
has
am
maximum
efficiency
of
92%
at
cruising
speed
(50
mp/h).
With
the
electric
drive
efficency
of
the
same
amount
we
only
need
a
4
kW
fuel
cell
stack
to
cruise
with
DESiE all day long.
