DRIVE

MOTOR

There

is

no

"wow

"

or

"flut

t

er"

caused

by

_

There is no

vibration

because

this

motor

has

no

mechanism.

The

is

extremely

low.

~ELECTRONIC

COMMUTATOR BRUSHLESS DC MOTOR

The

DC

motor

is

not

affected

by

fluctuations

of

the

power

supply

frequency

.

Starting

rotation

power

is large,

with

complete

stability

of speed reached

withi

n

one

-

half

r

otation

at

33-1/3

r_p.m_ Since there

is

no

electro-magnetic

hum,

the

signal

to

noi

se

ratio

(rumbl

e)

is

ex-

cellent.

And,

because the

motor

includes

an

electronic

commutator,

starting

is

perfectly

accurate,

There

is,

therefore,

no

speed

instability

or

brush

deterioration

as

is

often

noted

in brush

commutators,

no

pulse noise generated

by

brush

sparking and

no

sound caused

by

rubbing

of

brushes.

OROTATION

OF THE

TURNTABLE

PLATTER CAN

BE

STOPPED AT

ANY

TIME

Th

is is

a

feature

which

is

not

found

in

players

which

have speed

reduction

and transmissions de

vic

es

such

as

a

belt

or

idl

er.

If

such

stoppin

g

is

attempted

on

ordinary

players,

the

belt

or

idler

will

soon

deteriorate

and

efficiency

soon

becomes

poor.

In

this

player

system, such

stopping

causes

no

problem

other

than a s

light

increase

of

the

motor

current.

whic

is

not

a

is

extremely

good.

0ELECTRICAL

SPEED CHANGE

Ther

e is

no

mechanism

to

change

the

position

of

the

belt

or

idler.

There

is,

therefore,

no

"wow"

or

unwanted

speed change.

ONO

EFFECT FROM

FLUCTUATIONS

OF

POWER

SUPPLY

FREQUENCY

OR

VOLTAGE

Since the

motor

is

the

DC

type,

the

rotation

speed does

not

depend

on the

power

sup

ply

frequency.

And,

be

cause a

DC-stabilizer

is used,

the set is

not

affected

_by

changes

of

the

power

supply

voltage, even

if

the

fluctuation

is large.

(l)SEMI-PERMANENT

HIGH

PERFORMANCE

Unlike

there is

no

reduction

or

transmission mecha-

nism,

such

as

a

belt

or

id ler.

The

motor

rotates

the

turntable

platter

dir

ect

l

y,

at

an

ultar-Iow

speed.

Wear

of

parts

is

therefore,

reduced

to

minimum

and

high-

can

be

maintained

semi-permanently.
