TROUBLE SHOOTING - MOTOR(continued)
TROUBLE
PROBABLE CAUSE
Motor fails to develop
full power. (Power
output of motor decreases
rapidly with decrease in
voltage at motor terminals.
For example, a reduction
of 10% in voltage causes
a reduction of 19% in
maximum power output of
which the motor is capable,
while a reduction of 20%
in voltage causesa
reduction of 36% in
maximum power output.)
Motor starts slowly
or fails to come up
to full speed.
Motor
overheats.
Starting
relay in
motor will not
operate.
Motor stalls
(resulting in blown
fuses or tripped
circuit breakers),
Frequent opening of
fuses or circuit
breakers.
1. Power line overloaded
with
lights, appliances
and
other motors.
2. Undersize
wires or circuit
too long.
3. General overloading of
power company
facilities. (In some
sections of the
cOuntry, demand for
electrical power may
exceed the capacity
of existing generating
and distribution systems,)
4. Incorrect fuses or circuit
breaker in power line.
1. Low voltage will not
trip relay.
2. Windings
burned
out
or open.
3. Starting
relay not
operating.
1. Motor
overloaded.
2. Improper cooling. (Air
circulation restricted
through motor due to
sawdust, accumulating
inside of saw).
1. Burned
relay contacts
(due to extended
hold-in periods caused
by low
line voltage,etc.)
2. Saw not in upright
position.
3. Loose or broken
connections.
1, Starting
relay not
operating.
2. Voltage
too low to permit
motor
to reach operating
speed.
3. Fuses or circuit
breakers
do not have sufficient
capacity.
1. Motor overloaded.
2, Fuses or circuit breakers
do not have sufficient
capacity.
3. Starting relay not
operating (motor does
not reach normal speed).
REMEDY
1. Do not use other appliances
or motors
when using the saw.
2. Increase wire sizes, or reduce
length
of wiring.
See "Motor
Specifications
and Electrical
Requirements"
Section.
3. Request
a voltage check from
the power
company.
4. Install
correct
fuses or circuit
breakers.
1. Request
a voltage check from
the power
company.
2. Have motor
repaired
or replaced.
3, Have relay replaced,
1. Feed work slower into blade.
2.
Clean out sawdust
to provide
normal
air
circulation
through
motor.
See "Maintenance
and Lubrication"
Section.
1. Have relay replaced
and request
a voltage check
from the power
company.
2. Place saw in upright
position,
3. Have wiring
checked and repaired,
!. Have relay replaced.
2. Request a voltage check from the power company.
3. Install
proper
size fuses or circuit
breakers.
1. Feed work slower into blade.
2. Install proper size fuses or circuit breakers.
3. Have relay replaced,
