alternator, pma, permanent magnet alternatorUse these powerful permanent magnet alternators (PMA's) to make cheap electricity from Wind, Hydro, Steam and Bio-Diesel powered engines, or diesel/gas engines

Stop wasting up to 50% of your power energizing the coil of standard brush type alternators. Get a real PMA!

Eagle permanent magnet alternators are by no means standard "Automotive" alternators containing brushes and electro-magnetic coils. A PMA does not waste power by having to continuously create an energy intensive magnetic field.

If these voltages seem high just remember that standard automotive alternators are usually putting out 40 to 50 volts into the 12 volt battery in your car. That's right! It won't harm the battery AS long as the battery is not FULL it can take high levels of charging voltage no problem. A lead acid battery will easily buffer high input voltages. (You will never be able to see voltages this high because the battery pulls all power inputs DOWN to its own voltage level.)

A battery is basically a BIG capacitor in electronic terms. Once your batteries are fully charged you must THEN stop putting any additional power into it! See our Diversion Load page to divert power from a wind turbine when your batteries are full.


WIND TURBINE DESIGNERS HINT
When picking out a PMA the better choice is the higher voltage model. You don't want to be under powered. You MUST always exceed the batteries voltage to produce ANY net gain.
Wind is unpredictable so at low wind speeds you want to make sure that your PMA can still exceed the voltage of your battery bank. (11 volts going into a 12 volt battery = zero charge)

NOTE:
These Ratings below are ONLY to be used as a basic guide line.
Voltages are usually much higher than shown so except more.


How readings are derived
Since we do not know the torque of the driver, this data is given in absolute separate peaks.
Amps are read as a short in the circuit closed condition. Then we read Volts in the circuit open condition. These charts do not reflect working conditions only the absolute separate readings. An engineer can then use this data and extrapolate actual power by adding in actual Horsepower V. RPM and the torque properties of the particular driver in the application that the PMA is to be used in. This is the unknown data only the engineer can provide. The engineer can then decide on Voltage V. Amperage to be the dominant target factor based on individual necessity, current draw and the continuous available torque of the driver (engine, turbine etc.)

PLEASE NOTE:
VOLTAGES -
ARE RATED WITH CIRCUIT OPEN -
AMPERAGES - ARE RATED WITH CIRCUIT CLOSED-
ACTUAL CHARGING VOLTAGES MAY VARY DEPENDING ON YOUR SPECIFIC LOAD.
These curves shows the maximum Voltage OR Amperage
POTENTIAL but is not showing both SIMULTANEOUSLY!!!
Only YOUR specific LOAD can determine the final Wattage.


These PMA's have no over heat protection. If you try to charge a load that has a monstrous amperage draw these PMA's will try to push that load until the coils literally burn up. You especially have to exercise caution when using an engine to turn them. Use the proper circuit breaker and wire size for your load. No warranties on any burned up PMA's. If they start smoking or making a burning smell your load is simply to large. Run them slower or reduce the load!   Normal operating temperature 425 Degrees F.

NOTE:   PMA's used with engines driving them require a fan kit for cooling.

NOTE: All of our alternator pulleys and shafts are only guaranteed to be within .2 degrees of true because of slight imperfections in the metal during the pressing process. This will not effect the wattage or output power.
