Motor
and
Drive
Turntable
and
mechanism
are
driven
by
the
motor
130.
This
shaded-pole
motor
runs
vibration-free
in
radially
elastic
'mounts
and
has
extremely
lovv
magnetic
leakage.
The
motor
speed
is
independent
of
voltage,temperature,
and
load
variation.
lt
can
only
fluctuate
with
the
mains
frequency.
Two
motor
pulleys
permitadaptation
to
the
mains
frequency
of
either
50
or
60
Hz;
one
pulley
116
is
showin
in
both
Fig.
2
and
Fig.
3.
For
50
Hz
use
the
pulley
part
na.
261
938,
for
60
Hz
use
the
pulley
part
na.
261
939.
The
driving
force
is
transmitted
to
the
turntable
14
by
belt
17.
Speed
Selection
To
adjust
the
turntable
speed
to
either
33
1/3
or
45
rpm,
the
belt
17
is
shifted
to
the
one
step
of
pulley
116
with
the
associated
diameter
(see
Fig.

This
is
achieved
when
you
adjust
the
speed
lever

move
the
change-over
lever
into
the
desired

or
45
rpm)
posi-
tion.
When
the
record
player
is
turned
off,
,
the
changeover
lever
is
blocked
by
the
blocking
bar
and
the
speed
is
just
preselected.
Only
when
the
turntable
14
starts
running,
the
blocking
bar
8
will
release
the
change-over
lever.
The
latter
will
then
shift
the
belt
17
to
that
step
of
motor
pulley
116
which
corresponds
to
the
desired
speed.
