GENERATOR
INFORMATION
USE
OF
ELECTRIC
MOTORS
The power required
to
start
an
electric motor
is
considerably
more
than
is
required
to
keep it running after it
is
started.
Some motors require
much
more current
to
start them
than
others. Split-phase
(AC)
motors require more current
to
start,
under similar circumstances, than other types.
They
are
commonly used
on
easy-starting loads, such
as
washing
machines, or where loads
are
applied after the motor is
started, such
as
small power tools. Because
they
require 5
to
7 times
as
much current to start
as
to
run, their use should be
avoided,
whenever possible,
if
the electric motor
is
to
be
driven by a small generator. Capacitor
and
repulsion-
induction motors require from 2
to
4 times
as
much current
to
start
as
to
run.
The current required
to
start
any
motor
varies
with
the
load connected to
it.
An
electric motor con-
nected
to
an
air compressor, for example, will require more
current than a motor
to
which
no
load
is
connected.
In
general,
the
current
required
to
start
115-
Volt
motors
connected
to
medilUll
starting
loads
will
be
approximately
as
follows:

*NOTE:
In the above table the maximum
Amps
for
Starting
is
more for some small motors than
for
larger ones. The reason
for
this is that the hardest starting types (split-phase) are not
made
in
larger sizes.
Because the heavy surge
of
current needed for starting
motors
is
required
for only
an
instant, the generator will not
be damaged
if
it can bring the motor
up
to
speed in a
few
seconds.
If
difficulty
is
experienced
in
starting motors,
turn
off all other electrical loads and,
if
possible, reduce the load
on
the electric
motor.
REQUIRED
OPERATING
SPEED
Run
the
generator
first
with
no
load applied,
then
at
half
the
generator's capacity,
and
finally loaded
to
its
full
capacity
as
indicted
on
the generator's data plate. The output voltage
should
be
checked periodically to ensure proper operation of
the generating plant
and
the appliances it supplies.
If
an
AC
voltmeter or ampere meter
is
not
installed
to
monitor voltage
and load, check it with a portable meter and amp probe.
NOTE:
When the vessel in which the generator is installed
contains
AC
equipment
of
120 volts only, it is recommended
that the generator's
AC
terminal block be configured to
provide one
120 volt
AC
hot leg
for
the vessel's distribution
panel. This will ensure good motor starting response from the
generator.
GENERATOR
FREQUENCY
ADJUSTMENT
Frequency
is
a direct result of engine speed. The engine
has
been factory set
to
run
at
1800
rpm to produce a frequency
of 60
Hz.
Refer to GENERATOR FREQUENCY
ADJUSTMENT (HERTZ)
in
this
manual if
an
adjustment
is
necessary.
Generator
Maintenance
• Maintaining reasonable cleanliness
is
important.
Connections
of
terminal boards and rectifiers
may
become
corroded, and insulation surfaces may start conducting
if
salts,
dust,
engine exhaust,
carbOn,
etc.
are
allowed
to
build
up.
Clogged ventilation openings
may
cause
excessive heating and reduced life
of
windings.
• For unusually severe conditions, thin rust-inhibiting
petroleum-ba..<;e
coatings, should be sprayed or brushed
over all surfaces
to
n;duce rusting and corrosion.
• In addition
to
periodic cleaning, the generator should
be
inspected for
(a)
tightness of
all
connections,
(b)
evidence
of overheated terminals and
(c)
loose or damaged wires.
• The
drive
discs on single bearing generators should be
checked periodically
if
possible for tightness of screws
and for
any
evidence
of
incipient cracking failure. Discs
should
not
be allowed to become rusty because rust
may
accelerate cracking. The bolts which fasten
the
drive
disc
to
the generator shaft must be hardened steel
SAE
grade
8,
identified by 6 radial marks, one at each of the 6 cor-
ners of the head.
• The rear armature bearing
is
lubricated and sealed;
no
maintenance is required. However,
if
the bearing becomes
noisy or rough-sounding,
have
it replaced.
• Examine bearing
at
periodic intervals. No side movement
of shaft should
be
detected when
force
is
applied.
if
side
motion
is
detectable, bearings are wearing or wear
on
shaft of bearing socket outside bearing
has
occurred.
Repair must be made quickly or major components
will
rub
and
cause major damage to generator.
Carbon
Monoxide
Detector
WESTERBEKE recommends mounting a carbon
monoxide detector
in
the
vessels living quarters.
Carbon
monoxide, even
in
small amounts, is deadly.
The presence of carbon monoxide indicates
an
exhaust
leak
from
the engine or generator or
from
the
exhaust
elbow/exhaust hose, or that fumes
from
a nearby
vessel
are entering your boat.
If
carbon monoxide
is
present, ventilate the area with
clean air and correct the problem immediately!
