Carbon
free
Conventional
electric
motors
haven'tchanged
much
in
1
00
years.
Bulky
and
fragile.
The
brushes
wear
down
and
emit
carbon
dust.
The
Dyson
digital
motor
is
different.
Controlled
by
microchip
it spins
up
to
98,000
rpm
-
five-times
faster
than
a
modern
Indy
car
engine.
Because
of
its
speed,
the
digital
motor
is
half
the
size
and
half
the
weight.
With
no
brushes
or
fixed
magnets,
it
doesn't
emit
carbon
either.
