Signs that your generator stator is bad include no voltage, bad windings, burnt windings in the stator.
You can also tell if a generator stator is bad by checking the resistance with an OHM meter.
Using an OHM meter insert each probe into a stator socket.
You should read around 0.2 to 0.5 ohms.
If you show an open circuit with the “Open” or infinity reading or have higher resistance, then the stator is bad and you must replace it.
Sometimes the voltage regulator is the culprit of no voltage on a generator or low voltage output.
Or the generator has lost it's residual magnetism which can be restored using a grinder or 12 volt battery.
You can use a drill or grinder to restore the residual magnetism in the generator by starting the generator and plugging a grinder or drill into the generator then reverse the motor by hand or pushing the grinder and grinder disc on some concrete and the voltage should be restored.
If these tests all produce positive results, then the stator itself is good.
A new stator for a generator costs from $150.00 to $250.00 but can be as high as $1,500.00 depending on the size of generator stator.
A generator stator can repaired.
Although not all generator stators are worth the cost of repairing unless the stator is an expensive generator stator.
For small portable generators the cost of repairing the stator is likely as much as new generator stator or generator head or another generator.
A new generator stator and rotor set typically costs between $250 and $1,500.
They are stationary and rotating parts of any system that generates electricity.
The stator on a generator is the stationary part that the generator rotor spins around inside of.
In a generator, the stator of the generator converts the rotating magnetic field to electric current.
In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.
The stator and rotor both are the parts of the generator.
The significant difference between the rotor and the stator of the generator is that the rotor is the rotating part of the generator whereas the stator is the stationary part of the generator.
Motors have stators and rotors as well and the same is true for the motors as is for generators.
A generator is basically a motor in reverse that creates the electricity from another energy source spinning the stator.
The motor then uses the electricity from the generator to cause the motor to spin.
A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy.
Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
