1.
What
is
an
encoder
used
for?
Measure
the
rotational
speed
to
ensure
that
the
rotational
speed
of
a
whole
set
of
motors
is
the
same
and
the
speed
of
the
transferred
workpiece
is
the
same
2.Do
I
need
encoder
motor?
The
characteristic
of
the
Hall
encoder
motor
is
that
it
uses
a
Hall
encoder
motor
to
monitor
the
position
and
speed
of
the
motor,
which
has
high
accuracy,
high
stability,
and
a
wider
range
of
application
scenarios.
If
you
do
not
need
precise
control
of
the
motor's
operating
position
and
speed,
you
can
choose
a
regular
motor
without
a
Hall
encoder.
3.
Are
encoders
AC
or
DC?
The
output
of
the
Hall
encoder
is
generally
a
DC
signal,
and
the
DC
electric
field
signal
is
easier
to
process
and
collect
than
the
AC
electric
field
signal.
4.What
is
12V
DC
motor?
A
12V
DC
motor
is
a
type
of
motor
driven
by
a
DC
power
source,
with
a
voltage
of
12V.
It
is
composed
of
armature,
magnetic
pole,
brush,
bearing,
etc.,
and
can
be
used
in
fields
such
as
automobiles,
household
appliances,
mechanical
equipment,
etc.
According
to
the
power,
speed,
torque
and
other
parameters
of
the
motor,
it
can
be
divided
into
different
types
and
specifications
of
motors.
5.How
to
deliver
the
goods?
we
will
deliver
via
Express
such
as
UPS,FEDEX,DHL,TNT
etc.
It
is
fast
and
safety.If
goods
quantity
is
large,the
shipping
cost
will
be
cost-effective.
