if by asking this im assuming the generator is face bolted to motor , if this is so , to save from having another front bearing , the gen stator is directed attached to motor shaft , on the far end under end bell cover is the end of shaft , a long bolt goes thru gen shaft to screw into motor shaft , MARK/photograph all the wires you unhook helps a lot when puting back together
What type of load (electrical) was hooked up to this generation?? If the surge
voltage and current was exceeded above the generator maximum for any length of
time. There problems, it could be the regulator, insulation burnt off the
I am taking a guess here. Now, 7100 Watts is it typical surge wattage. This
mean that the generator will deliver 7100 Watt (voltage times current) this is
know as the power factor. The actual operating load would be 6800 Watts and I
would even operator the generator at its peak wattage. Something in the
neighborhood of 10--15% less the peak wattage. Therefore a good positive
theatrical Wattage would be 5800 to 6350 operating wattage. Then this generator
would run all day.
Just remember Ohm's Law. Current plays a big factor in loading of a generator
while the operation voltage is at 120 AC Volts. Example: electric motor; Now
electric motor when starting will pull three time its operation current.
Operating current for a 1/2 HP AC motor is 6 amperes but start this electric
motor will require 18 amperes. This is one reason why they starting capacitors
on smaller electric motors. Larger three phase electric motor can literal stop a
generator cold...in its tracks. It put such a large demand on the generator it
stops the engine powering the generator. I have seen crankshaft break because
the generator could handle the heavy current load.
Remember, any time you are running a small gas powered generator. All ways
figure what the load and surge current load will be before hooking up any
generator. Normally this is figured in VA (volt/amps). Wish you lock.
Could be motor locked up or cord caught in the rewinding mechanism. Remove top engine cover and see if cord pulls now. If not then in winder. If it does see if you can turn the motor over by hand with cover off. If not maybe engine locked up. Did the engine run low on oil? if so when motor cooled, things may have locked up. Try removing spark plug, and light oil to cylinder and let soak.Turn engine with wrench.
The armature (rotating field) is powered by the voltage regulator for 'excitation' which is the term describing a magnetic, revolving field. This magnetic field 'induces' voltage into the stator windings (stationary outer winding), producing voltage for use at the recepticles. Some older generators used a 'permanent magnet field, instead of using a powered winding from a regulator and the voltage and frequency were set by the RPM. Frequency is still a function of RPM, but the voltage is controlled by the voltage regulator.
