PMG Charts and Graphs Page

This information can be helpful in troubleshooting and evaluation of the product in may not go up as fast as you like, please hit the link below and tell us what you'd like different or added. I have not seen any troubles in stator windings, nor have I received reports of them. I am building this information for reference and future trouble shooting..      

3KW PMG, AC

Above: Stator connected in Parallel 120VAC only operation

If you separate the individual Stator windings, and consult this chart, you might use it to verify the windings are good. If you find a stator winding producing a lower voltage, AND you have verified the RPM, then it is possible you have a number of coils shorted.

Above: PMG with the two stator windings in parallel and connected to a full wave bridge rectifier ad tied to a 1100 Ampere hour 4325 pound 48 volt battery! The Air cooled rectifier was running around 140F with a fanon it, and the PMG remained cool at 32 amps. After running for 10 minutes, the warmest spot on the PMG was 106F, and there was no overshoot after stopping the PMG. I will need to run the PMG for several hours at this load before I recommend it, but it sure looks like an easy load for the PMG to carry. Battery started out at 49.3 volts, and even though this battery is massive, this is PLENTY of charge current.

Above: All generators have a tendency to produce a different voltage from cold to warm.  In the Above diagram, we see the PMG at 60hz, 3000 WATTS of load over 90 minutes of time, we see the voltage is stable after about 50 minutes of running.
