Generator Not Producing Power ? Stator Winding


There are 4 requirements that have to be met before a generator is able to produce power. Due to number of questions that have been asked, a Coleman PowerMate 1500-1850 with a Briggs and Stratton Engine will be used here.

1) The Engine has to be turning at correct speed
2) Field Winding (Rotor) on the alternator must be energized
3) AC Winding (Stator) must create a voltage in presence of magnetic field
4) Output passes through Safety Devices before it reaches an outlet.

This Tip will cover the Stator Winding.

The stator winding is the winding that is around the outside of the rotor. It doesn't usually move. Previously, the alternator design was called a revolving armature, in which the field was stationary (outside), and the stator (armature) was the rotating member. This quickly was replaced, eventually, by the revolvingfield configuration, since the brushes carry a relatively small DCcurrent, rather than a larger AC current with destructive arcing. Brushes were prone to failure due to high wear.

In the revolving field architecture,there are primarily 3 types of alternators: Single Output, MultiOutput, and MultiPhase.

The single output alternator is just that, it outputs a single voltage. Typically, it will be either120vac (60Hz), or a single phase 240vac (50Hz) depending on the country it was bought in. The stator winding of this kind of alternator has only a single winding, with 2 wires coming off of it. One of these wires goes to the neutral bus for the outlets, the other wire goes to the circuit breaker, and the other side of the circuit breaker goes to the outlet. Disconnect both of the wires, and use your multimeter to check the continuity between them. You should have continuity here. Also check each wire to the frame of the alternator, there should not be continuity here though. If you don't have continuity between the wires, or if you have continuity between the wire and alternator frame, then you have what is called a grounded winding. This will have to be addressed by a motor shop, or replace the stator in its entirety. It is generally more cost effective to replace the generator though. Remove and sell the copper wire, and use that money towards a replacement generator.

Multiple Output alternators are usually found in the next step up from "bargain" generators. These usually will have an output of 120/240vac, and likely a low voltage battery charging circuit as well (12vdc being most common). The stator for these is checked in the same way as a single output, with a caution on the low voltage winding. On the low voltage winding,there will be a single diode (called half wave rectification) or a full wave rectifier (2 diodes) connected to the windings. You must disconnect at least 1 wire from the diodes to check the windings, and both wires to check for continuity between the windings and the frame of the alternator. If you don't disconnect the wire(s), the 1 way nature of the diode will indicate no continuity when there should be,and may cause you to not see continuity when there actually is (to the frame).

If the low voltage winding is open, the generator is still usable for the 120/240vac features. You just won't have benefit of the low voltage battery charging circuit, which is actually a very poor charger to begin with.

On a 120/240vac alternator, there may also be a switch that turns the 240vac on and off at the receptacle. This switch is put here so that the 2 120vac windings can be put in parallel for greater current capacity if 240vac is not required. If you have 120vac, but not 240vac, and the circuit breakers are not tripped, this switch is likely the culprit. It is just a double pole double throw switch that is easily replaced with one of the same type, and same or higher current rating. Never switch from 120 to120/240vac or vice versa while the engine is running. To do so invites winding damage due to arc-over, and may damage any devices that are connected from the voltage spike.

MultiPhase alternators are nothing more than single output alternators with a twist. Rather than having a single winding, there will be 3 windings, with a 120 degree phase separation. The in phase neutral wires will all be tied together, but the phase outputs will be separated, and connected to the receptacle in a specific order. This is called a Wye (Y) configuration. An alternate configuration is when the windings are all connected to each other, end to end style. The junction of each connection is then brought out to the receptacle. This is called a Delta configuration. Three phase / multiphase alternators will not be discussed in depth here as a much higher technical knowledge will be required.

As far as the stator winding goes, that is it. If you have continuity where you should, and don't have continuity where you shouldn't, the stator winding is likely good. As mentioned, if the low voltage battery charge winding is open, but not grounded / shorted to the frame, the primary function of the alternator is still usable.

If your checks of the stator are good,time to move on to the next tip.

Won't stay running


Do you know how to get the codes from the start switch in the generator itself? if not I can help, that will narrow down what can cause it. There are many fcactors, fuel, control board A1, rotor brushes etc. So we need to determine more. If you need help getting the codes please post, if you still need help with this problem

55kva gfwison generatore having trouble of no output voltage showing nor it feeding


If it is an FG Wilson 55KW Olympian you need to check the AVR and make sure it has a field output feeding the exciter stator, then check the rotor diodes, check each one with a meter, low res one way high the other with meter leads. If any are bad change them all, check the exciter rotor, then the main rotor and stator for open or shorted windings. If you give me the exact model I can maybe help more

Voltage shows 80 on 110v and 155 on 240v


if you take the end of the generator off you will see a rectifier or four diodes with a varister or a full wave brige rectifier, sounds like you have a bad diode, or a shorted exite winding to the rotor, the exite winding is a small turn winding feeds the rectifier board that ac signal is converted to dc to feed the rotor ,the rotor produces a magnetic field which rotates inside the stator windings , the magnetic lines of flux from this field cut through thre stator winding inducing a voltage in the stator coils. hope this helps

Coleman powermate generator has no output. have changed diodes, capacitor and brushes. i have 12 volts across the brushes but no output at the receptacles. coleman powermate 0545005 5000w


Disconnect the leads going to the brushes, and check for continuity (resistance) of the field winding. You should be able to measure *something* on the order of a few ohms. If you have resistance, then check each brush contact to the shaft that the field winding is on. There should not be any resistance at all, if there is, you have a shorted field winding and will need to be replaced.

Check the resistance of the stator winding next, make sure that nothing is connected to the generator, disconnect the stator wires if you are able (label them!). Check for resistance between the leads (2 wires for a 2 pole, 4 wires for a 4 pole). If there is no resistance, then the stator is open, and will need to be replaced. Also check for resistance from each wire to the frame of the alternator, there should not be any resistance here (indicating a shorted stator). If there is, then you have a shorted stator, and will need to have it replaced.

Replacement is likely to be impractical, probably cheaper to buy another generator with the same engine and keep the old engine as a spare. Still, contact an automotive starter / alternator shop for prices.

Trying to verify that the stator is bad. Its a 2002 sportsman 90. I have the manual but it still doesn't tell you what to do if the the specs are out. The only test that is not checking out would be...


the fact that you only get 47 volts indicates the stator has an open, there is nothing else but the stator that causes this low un-regulated voltage reading, all stators are tested the sam no matter what they come out of, car motorcycle, ATV etc.
here is the basic test.

STATOR TESTING.—The stator winding can be tested for opens and grounds after it has been disconnected from the alternator end frame. If the ohmmeter reading is low or the test lamp lights when connected between each pair of stator leads (fig. 2-31), the stator winding is electrically good. A high ohmmeter reading or failure of the test lamp to light when connected from any one of the leads to
the stator frame (fig. 2-32) indicates the windings are not grounded. It is not practical to test the stator for shorts due to the very low resistance of the winding.

Time left display flashes LE.


It is a locked motor error. One of the following is causing the problem but you may need the help of a qualified appliance technician:
  1. The connector (3-pin, male, white) in the motor harness is not connected to the connector (3-pin, female, white) of the stator assembly. Connect them properly.
  2. The electrical contacts between the connectors (3-pin, male, white) in the motor harness and 4-pin, female, white connector in the main board assembly is bad or unstable. Clean the connectors and connect them properly.
  3. The motor harness between the stator assembly and main board assembly is cut or open. Reconnect or rewire.
  4. Motor winding is defective. Check the resistance between the terminals of the stator. Resistance should be between 5 to 10 ohms, else replace the stator.
  5. The hall sensor is out of order/defective. It is located at the stator assembly. If the hall sensor is out of order, it cannot detect magnetic field and the main board sees it as the rotor is locked then displaying the error code. Replace it if no evidence of defect is found above.
