Stepper Motor Driven
Goniometer Stage
|
Three Phase Brushless Servo Motor with Quadrature Incremental
Optical Encoder Driven
Linear Goniometer Stage
|
|

The
AK120-45
Goniometer
Series
features
precision
ground
worm
gears
with
a
296:1
ratio
and
pre-loaded
cross
roller
guides,
and
+/-
45
degrees
of
travel
with
10
kg
of
load.
The
very
high
resolution
of
0.0006
degrees
(2.16
Arcsec.)
is
realized
when
using
the
standard
Two-Phase
Stepper
Motor
driven
by a
10
micro-steps
per
step
micro-stepping
driver
or
with
the
Servo
Motor
options
and
Quadrature
Optical
Encoders.
.
The
AK120-45
Series
of
goniometer
stages
feature
four
motor
options.
The
-01
option
is
Stepper
Motor
driven.
The
-02
option
(pictured)
is
driven
by a
Three-Phase
Brushless
Servo
Motor
with
a
Quadrature
Optical
Encoder,
the
-03
version
is
DC
Brushed
Servo
Motor
Driven
with
a
Quadrature
Optical
Encoder,
and
the
-04
option
is
Stepper
Motor
Driven
with
the
knob
replaced
with
a
Quadrature
Optical
Encoder
for
position
verification.
The
highest
resolutions,
accuracy,
and
travel
speeds
are
achieved
with
the
servo
motor
options
-02
and
-03.
This
AK120-45
Goniometer
Series
of
Stages
has
a
large
104
mm
long
by
90
mm
wide
table
with
a
precision
pattern
of
mounting
holes
for
precise
location
of
fixtures.
The
height
of
rotation
is
40.5
mm
above
the
surface
of
the
table
and
the
radius
of
rotation
is
67
mm
making
them
ideal
for:
Microscopy,
crystallography,
measurement
of
surgical
cutting
blades,
laser
positioning,
light
measurement,
and
inspection
applications.
This stage requires a
Motion Controller
that can be ordered as a complete plug-and-play system with RS-232, USB, joystick, trackball, and keypad control.
