Features a 303 Stainless Steel Shaft for ultimate Corrosion Protection and Increased Power. The shaft also features a standard thread size of 5/8 x 18 threads per inch and a KEYWAY to simplify adaptation to your project .

It has a 5mm x 5mm x 12mm keyway in the shaft in order to make custom applications easier to apply. Using the key will ensure that a counterclockwise rotation will not loosen the shaft nut. It will also make it easier to use a lovejoy, etc. The pulley and spacers still need to be sandwiched between the shaft nut and front spacer. Failure to do so will result in damage to the PMA.

The DC-512 model is best suited for motor driven applications or very high wind locations when used in a wind generator setup. Reaches 12 Volts at 650 RPM The chart below represents actual output on a test stand. Voltage readings were recorded with the circuit open (No Load) while Amperage was recorded with the output shorted (Max Load). Your system setup will determine what output you will see in the “real world”. For example a dead battery will pull much more current similar to the shorted output reading than will a fully charged battery. Also the voltage will rise until it meets the voltage of your battery and then level off as the battery is “absorbing” the excess voltage as it charges. This unit can handle up to 10,000 RPM. The output is unregulated. You should be sure and run a 40 or 50 amp fuse on the output to prevent damage to the unit if your load becomes excessive. Also consider using a charge regulator so your batteries don’t become overcharged. On our test stand with a 12 Volt battery connected the PMA produced 40 Amps at 2000 RPM.

Shaft Threads are 5/8 x 18 tpi

For use as a direct drive wind generator, select a fast set of blades and you should start charging a 12 volt battery setup in about 15 mph winds. This unit passes the 12 volt mark at just 650 RPMs. The “Hyper-Spin” rotor will work but a better choice would be to design a gear up system of some sort. Many other websites offer good rotor designs and even plans for rotors if you would like to build your own, just make sure it has a 17mm hub to fit a standard Delco alternator shaft.

  • This PMA unit features the following:
  • Completely Brushless design eliminates the need for maintenance and reduces friction.
  • Specially wound High-Output stator.
  • Super Strong N50 grade Neodymium rare earth magnets are at its core to replace the inefficient electromagnetic field coil.
  • Zero Cogging
  • It is built using Brand New GM Delco alternator components including NEW Stator Coils, factory balanced Stainless Steel shafts and Rotor Pole Shoes. Replacement bearings and parts will be available for years.
  • Built-in rectifier. (DC output is unregulated)
  • This unit can be used in a direct drive high wind turbine, hydro-electric application, or driven with a small gasoline or diesel engine.
  • Pulley and cooling fan included.
  • Built to last with new bearings and a baked on clear ceramic finish that will last for years in harsh outdoor environments.
  • 90 day full replacement warranty on all units (Warranty void if PMA has been opened or tampered with)
  • Reaches 12 Volts output at just 650 RPM and the voltage keeps going up from there.
  • Produces up to 40 Amps into a 12 Volt battery at 2000 RPM

Reviewer: Brian Helsley from Hagerman, ID United States  
I recieved my PMA and a Tristar 45 amp controler a day before it was to be delivered... AWSOME PACKAGING as well as one on one Q and A with the company. I asked for ceartin parts to be loosened before packaging, and they did so. I will for sure ask them for advice as well as ordering more PMA's
