Starting Electric Motors - Electric motors require much
more current (amps) to start them than to run them.
Some motors, particularly low cost split-phase motors,
are very hard to start and require 5 to 7 times as much
current to start them as to run them. Capacitor motors
are easier to start and usually require 2 to 4 times as
much current to start them as to run them. Repulsion
Induction motors are the easiest to start and usually
require 1 1/2 to 2 1/2 times as much to start them as to
run them.
Most fractional horsepower motors take about the same
amount of current to run them whether they are of
Repulsion-Induction (RI), Capacitor (Cap), or Split-Phase
(SP) type. The chart below shows the approximate
current required to start and run various types and sizes
of 120 volt 60 cycle electric motors under average load
conditions.
RUNNING STARTING AMPS
HP AMPS SP CAP RI
1/6 3.2 16 TO 22 6 TO 13 5 TO 8
1/4 4.5 22 TO 32 9 TO 18 7 TO 12
1/3 5.2 26 TO 35 10 TO 21 8 TO 17
1/2 7.2 NOT MADE 14 TO 29 11 TO 18
1 13.0 NOT MADE 26 TO 52 20 TO 33
The figures given above are for an average load such as
a blower or fan. If the electric motor is connected to a
hard starting load such as an air compressor, it will
require more starting current. If it is connected to a light
load, or no load such as a power saw, it will require less
starting current. The exact requirement will also vary with
the brand or design of the motor.
Self-excited generators respond to severe overloading
differently than the power line. When overloaded, the
engine is not able to supply enough power to bring the
electric motor up to operating speed. The generator
responds with high initial starting current, but the engine
speed drops sharply. The overload may stall the engine.
If allowed to operate at very low speeds, the electric
motor starting winding will burn out in a short time. The
generator winding might also be damaged.
CAUTION: EQUIPMENT DAMAGE
RUNNING THE GENERATOR SET UNDER THESE
CONDITIONS MAY RESULT IN DAMAGING THE
GENERATOR STATOR AS WELL AS THE MOTOR
WINDING.
Because the heavy surge of current required 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 of time. If difficulty is experienced in starting
motors, turn all other electrical loads off and if possible
reduce the load on the electric motor.
Motor Starting Capacity - listed below you will find the
motor starting capability of your engine generator set.
Generator Motor Size
Model (code “G” capacitor start)
W6010DR 3.0 HP
Trying to start a larger motor or higher code (ie. J or K) motor
may result in damage to both the generator and the electric
motor especially 120 volt motors.
CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITHOUT OIL. Failure
to maintain the engine oil at the proper level will result in
serious engine damage.
UNPACKING
When you unpack your new ENGINE GENERATOR, be
sure to remove all the information sheets and manuals
from the carton.
1. This power plant was in good order when shipped.
Inspect the power plant promptly after receiving it. If
damage is noted, notify the transportation company
immediately; request proper procedures for filing a
“concealed damage” claim. Title to the equipment
and responsibility for filing claim rests with you when
a generator is sent F.O.B. shipping point. Only you
can legally file a claim.
2. Before proceeding with the preparation of your new
engine generator set for operation, take a couple of
minutes to insure that the unit you have received is
the correct model and review the specification pages
in this manual to insure that this unit fits your job
requirements.
3. After removing the engine generator from the carton
locate and remove the shipping strap attached to the
generator shock mount. See attached tag for removal
instructions.
UNIT PREPARATION
Before your engine generator was shipped from our
factory it was fully checked for performance. The generator
was load tested to its full capacity, and the voltage and
frequency were carefully checked and adjusted.
Proper Oil Level
