DESCRIPTION

The
alternator

incorporates
an
Ie

voltage
regulator
which
maintains
volt

age
within
the

specified
range
and

prevents

output
voltage
from

rising

higher
than
the

specified
value

Except

for
the
Ie
circuit

alternator

parts
are

essentially
the

same
as
those
of

the

conventional

type
alternator

Service

procedures
outlined
in

this

section
are
restricted
to
information

on

other
than
the

voltage
regulator

In
the

alternator
a

magnetic

Electrical

System

ALTERNATOR

produced

by
the
rotor
which
consists

of

alternator
shaft
field
coil

pole

pieces
and

slip

rings
The

slip
rings

pressed
in
the

shaft
conduct

only
a

small

field
current

Output
current
is

generated
in
the
armature
coils
located

in
the
stator
The
stator
has
three

windings
and

generates
three

phase

alternating
current
Silicon
diodes
act

like
a

one

way
valve
for

electricity
so

that

charging
current

passes
easily
but

reverse
current
is
shut
out

In
this
alternator

pack
type
silicon
diodes
are
used

as
main
diodes

Nine

diodes
three

negative
three

positive
and
three

sub
diodes
are

installed
in

positive
and

negative
plates

as
an

assembly

These

diodes
are
direct

soldered
at

their

tips
and

constructed
with

posi

tive
and

negative
conjunction

They
are
mounted
on
the
two

plates
which
combine
the

function
of

heat

dissipating

and

positive

terminals
and
are

light
in

weight
and

easy

consists

essentially
of

incorporating
tran

These

admit

thus

maintaining
its

output

Should

any

In
the

charge

circuit
a
diode
is
at

to
the

to

so
that

the

The

which

generates
the

required
for
the

make

of
the

primary

The

is

supplied

by

The

resulting
in

The

then

the

Then
the
