The

is

a

DC

electronic

motor.

The

electro-mechanical

commutation

normally

carried

out

on

mo-

tors

by

the

commutator

is

electronically

controlled

in

the

case

of

the

Dual

EDS

by

two

Hall

generators.

These

Hall

genera-

tors

-

dependent

-

control

four

The

cyclic

switching

of

the

field

coils

exerts

rotating

magnetic

field

on

the

eight-pole

annular

magnet

of

the

rotor.

The

field

coils

are

located

in

the

air

gap

between

the

annu-

lar

magnet

and

the

return

path

plate

which

form

the

magnetic

return

path.

The

speed

is

controlled

by

a

frequency

generator

which

is

coupled

to

the

rotor

rigidly.

A

fixed

flat

coil

is

located

in

a

magnetic

circle

which

is

formed

by

a

200

pole

permanent

annular

magnet,

a

toothed

disk

and

a

return

path

cup.

The

toothed

disk

rotates

with

the

rotor

and

generates

a

frequency

in

the

coil

which

is

proportional

to

the

speed.

Any

error

which

might

be

caused

by

eccentricity

between

the

permanent

magnet

and

toothed

disk

is

compensated

thus

generating

a

fre-

quency

of

high

uniformity

which

controls

the

regulating

circuit.

This

frequency

is

transformed

by

a

special

electronic

circuit

into

a

DC

voltage

which

is

proportional

to

speed

(digital/analog

transformation).

The

voltage

thus

generated

is

compared

to

a

highly

stabilized

reference

voltage

and

used

to

control

current

of

the

direct

drive.

The

The

rotates

with

a

toothed

disk

having

200

teeth.

A

magnetic

tape

is

cemented

round

the

motor

flange.

On

one

side

the

tape

has

200

north

poles

on

the

other

side

200

south

poles.

The

north

poles

are

arranged

directly

opposite

the

rotor

center.

A

coil

is

mounted

in

the

vicinity

of

the

magnetic

tape

and

the

toothed

disk.

A

changing

magnetic

field

is

produced

by

the

rotating

toothed

disk.

This

magnetic

field

induces

in

the

coil

a

voltage

with

the

corresponding

frequency.

This

fre-

quency

is

a

rotational

The

5

(via

which,

together

with

The

The

For

forward

(I)

lift

cam

(184)

rotates.

The

slide

bar

(211)

con-

nected

to

it

transmits

this

movement

to

the

lift

(201)

(via

the

compensating

cam

(207)

which

then

raises

the

tonearm.

As

a

result,

the

cue

control

permits

setdown

of

the

tonearm

at

any

desired

point.

The

lever

(183)

is

released

by

moving

the

cue

control

lever

rearwards

(1).

As

a

result

of

the

action

of

compression

spring

(203)

the

lift

(201)

is

brought

back

to

its

normal

position

and

the

tonearm

lowered

slow-

ly.

Lowering

of

the

tonearm

is

damped

by

si-

licone

oil

in

the

lift

tube.

The

height

of

the

stylus

above

the

record

can

be

varied

by

turning

the

adjustment

The

distance

should

be

approximately

5

Turning

the

tonearm

ing

motor

(18)

and

rotating.

The

shut—off

cycle

after

placing

a

record

is

initated

by

the

dog

(M)

of

the

platter

(4)

and

shut—off

lever

(163).

The

shut—off

lever

(163)

is

guided

onto

the

dog

by

the

movement

of

the

tonearm

when

play—

the

record

with

the

aid

of

the

shut—off

bar

(164)

proportionate

to

the

groove

The

eccentrically—mounted

dog

forces

the

shut—off

lever

(163)

back

with

each

revolution

as

long

as

the

advance

of

the

tonearm

only

amounts

to

the

width

of

one

groove.

Only

the

run—out

groove

with

its

increased

lead

guides

the

shut—off

lever

(163)

onto

the

dog

at

a

higher

rate

so

that

the

shut—

off

lever

is

picked

up

and

moved

along

(Fig.

As

a

result

the

shift

arm

is

brought

into

its

neutral

position

inter—

rupting

the

Simultaneously,

the

the

unit

is

equipped

with

a

muting

switch.

When

moving

the

tonearm

(48)

inwards

the

con-

tact

springs

are

actuated

by

pivoted

lauer

(179)

(139)

on

the

con-

trol

After

playing

a

the

contacts

are

clos-

returned

to

its

rest,

the

contacts

are

reopened.

Points:

a)

The
