Motor - 2
Problem
Probable Cause What to Do
Motor fails to develop full
power.
(Power output of motor
decreases rapidly with
decrease in voltage at
motor terminals. For ex-
ample: a reduction of
10% in voltage causes a
reduction of 19% in maxi-
mum power output of
which the motor is
capable, while a reduction
of 20% in voltage causes a
reduction of 36% in maxi-
mum power output.)
Power line overloaded with
lights, appliances, and other
motors.
Reduce the line load.
Undersize wires or circuit too
long.
Increase wire sizes, or reduce
length of wiring.
General overloading of power
company's facilities.
(In many sections of the
country, demand for electrical
power exceeds the capacity of
existing generating and distribu-
tion systems).
Request a voltage check from
power company.
Motor overheats. Excessive feed rate when
crosscutting or ripping.
Slow down rate of feed.
Improper cooling.
(Air circulation restricted
through motor due to sawdust,
etc.)
Clean out sawdust to provide
normal air circulation through
motor.
Saw blade has heel.
Refer to Making Blade Parallel
to Table section.
Motor starts slowly or
fails to come up to full
speed.
Starting switch will not trip due
to low voltage.
Correct low voltage condition.
Motor stalls resulting in
blown fuses or tripped cir-
cuit breakers.
Voltage too low to permit Correct the low line voltage con-
motor to reach operating speed, dition.
Fuses or circuit breakers do not Replace fuses or circuit
have sufficient capacity, breakers with proper capacity
units.
Frequent opening of fuses
or circuit breakers.
Motor overloaded.
Fuses or circuit breakers do not
have sufficient capacity.
Reduce motor load.
Replace fuses or circuit
breakers.
