(a) Hard-starting motors require 3 to 5 times
the rated running watts.
(b) These loads may require up to 15 minutes
to restart due to its normal build up of
compressor.
CAUTION: Always allow the generator
to reach operating speed before a load is
applied.
6.2 Starting electric motors
Electric motors require much more current
(amps) to start than to run. Some motors,
particularly low cost split-phase motors, are
very hard to start and require 5 to 7 times
more current to start than to run, Capacitor
motors are easier to start and usually require
2 to 4 times as much current to start than to
run. Repulsion induction motors are the
easiest to start and require 1.5 to 2.5 times as
much to start than to run.
Most fractional 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 following
chart shows the approximate current required
to start and run Cap type and size of 220 volt
50cycle electric motors under various
conditions.

The figures given above are for an average
load such as a blower of 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.
CAUTION: To start the motor above
1.5kw power. The G2, G3 grade
generator should be selected and
method of drop voltage starting must be
carried out. For detailed step, consult
with our dealer or with us directly.
