direct
drive
system
The
newly
developed
direct
drive
system
of
the
CS
731
Q
turn-
table
is
a
successful
synthesis
of
our
well-known
motor
principle
and
a
highly
sensitive
electronic
system
which
receives
its
accu-
racy
from
a
quartz
crystal.
The
drive
motor
is
a
DC
motor
with
no
commutator
in
which
commutation
is
carried
out
by
two
Hall
generators
which
detect
the
position
of
the
rotor
equipped
with
an
8
-pole
ring
magnet
and
which
also
actuate
the
corresponding
windings
of
the
rigid
flat
coils.
The
synchronously
rotating
mag-
netic
return
circuit
plate
and
the
ring
magnet
enclose
with
a
small
air
gap
the
non-ferrous
coil
arrangement
so
that,
on
the
one
hand,
the
drive
system
displays
an
extremely
uniform
running
characteristic
without
pole
sensitivity
and
which
displays,
on
the
other
hand,
a
high
torque
in
spite
of
the
economical
energy
supply.
After
the
nominal
speed
has
been
attained,
the
energy
supply
required
for
maintenance
of
rotation
is
less
than
50
mW.

Description
of
function
At
a
motor
speed
of
33
1/3
rpm,
the
200
-pole
frequency
genera-
tor
rigidly
coupled
to
the
motor
delivers
a
frequency
of
111
Hz
which
is
amplified
in
the
input
amplifier
and
prepared
in
the
cam
form.
This
Signal
is
applied
as
an
actual
value
to
the
PLL
circuit.
An
oscillation
frequency
of
4.608
MHz,
which
is
control
led
by
a
highly
precise
quartz
crystal,
is
generated
in
the
quartz
oscillator.
The
actual
reference
frequency
—
that
is
to
say,
the
set
value
—
is
derived
from
the
oscillator
frequency
by
a
multi-stage
divider.
In
the
PLL
circuit,
the
actual
value
and
set
value
are
compared
with
one
another
as
regards
amount
and
phase.
In
the
case
of
the
slightest
deviation,
a
control
pulse
is
applied
to
the
digital/analog
converter
which
obtains
from
this
an
analog
control
signal
which
is
converted
into
a
current
alteration
in
the
subsequently
connec-
ted
motor
control
circuit.
In
the
drive
motor,
this
current
altera-
tion
causes
spontaneous
stabilization
of
the
minimal
speed
devia-
tion.

The
set
value
necessary
for
the
45
rpm
speed
is
generated
in
the
voltage
divider
by
alteration
of
the
divider
ratio.
For
pitch
control,
a
continuously
variable
control
signal
,
with
which
the
control
loop
is
fed,
is
obtained
by
means
of
a
complicated
division
pro-
cess.
Thus
the
complete
control
range,
like
the
nominal
speeds,
is
coupled
in
a
locked-phase
relation
to
the
quartz
oscillator.
The
speed
accuracy
in
the
pitch
range
is
practically
the
same
as
in
the
case
of
nominal
speed.
The
speed
deviation
preselected
with
both
pitch
controls
is
maintained
even
if
the
pitch
switch
is
operated
or
if
the
unit
is
seitched
off.
In
the
speed
logic,
the
display
unit
of
the
CS
731
0
obtains
from
the
actual
speed
the
basic
information
as
to
whether
the
actual
speed
of
the
nominal
speed
is
faster
or
slower.
A
further
logic
sy-
stem
activates
the
plus
or
minus
sign
of
the
display
unit.
Both
signals
are
dark
at
rated
speed.
From
the
digital
information
on
the
actual
speed,
a
further
digital/analog
converter
receives
relative
and
analog
information
which
is
transformed
in
the
cascade
switch
to
an
activation
voltage
for
the
13
digital
displays.
In
the
display
itself
the
information
is
still
completely
analog
as
the
individual
digits
are
activated
with
differentiated
voltages
and
light
up
accordingly.
This
display
is
as
accurate
as
it
is
practical.
The
power
section
supplies
the
various
partial
circuits
with
carefully
filtered
and
stable
operating
voltages.

each
of
the
two
rated
speeds,
33
1/3
and
45
rpm,
can
be
varied
by
±
5.5
%.
With
the
seesaw
switch
(16)
at
"ON"
position,
each
nominal
speed
can
be
altered
by
means
of
a
separate
potentiometer
(14).
At
the
same
time,
the
optoelectronic
display
scale
(35)
indicates
the
percentage
deviation
from
the
nominal
speed.
I
ndependently
of
the
potentiometer
setting
(14),
the
speed
cor-
responds
with
quartz
precision
to
the
respectively
switched

The
stroboscope
markings
on
the
turntable
edge
are
flashed
from
the
diode
plate
(148)
by
means
of
quartz

Tonearm
and
tonearm
suspension
The
light,
torsion-resistant
all-metal
tonearm
is
twingimbal
mounted.
Suspension
is
by
means
of
four
hardened
and
precision
polished
steel
points
which
rest
in
precision
ball
bearings.
The
tonearm
bearing
friction
is
thus
reduced
to
a
minimum.

force
corresponding
to
the
built-in
pick
-up
cartridge
the
tonearm
is
balanced
at
0
position
of
the

is
carried
out
by
moving
the
weight
with
stem
(60)
subsequent
fine

The
balance
weight
is
designed
so
that
pick
-up
cartridges
having
a
dead
weight
(including
fitting
material)
of
2
—

g
can
be
balanced.
The
tracking
force
is
produced
by
tensioning
the
coil
spring
fitted
in
the
spring
housing
(74).
The
rotary

Lubricating
instructions
All
bearing
and
friction
points
of
the
unit
are
adequately
lubricated
at
the
factory.
Replenishment
of
oil
and
grease
is
only
necessary
after
approx.
2
years
of
normal
use
as
the
most
important
bearing
points
have
sintered
metal
bushes.
The
motor
bearings
have
long-life
sintered
metal
bushings
and
thus
should
not
be
lubricated.
Bearing
points
and
friction
faces
should
be
lubricated
sparingly
rather
than
generously.
When
using
dif-
ferent
lubricants,
chemical
de-
composition
can
often
take
place.
To
prevent
lubrication
failure,
we
recommend
using
the
original
lubricants
shown
below.
