Features a Standard Delco Steel Shaft. The shaft features a thread size of 0.668 x 20 threads per inch

Does not include an AC output pigtail.

The DC-440 Model is our basic unit and perfect for use as a wind generator for those on a budget. Works best in areas that experience average winds of 5-15 MPH. It can also be used in Hydro applications. This Model Reaches 12 Volts at 150 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. The output is unregulated. You should be sure and run a 20 or 30 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 15 Amps at 2000 RPM.

Threads on shaft are .668 x 20 threads per inch

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 6 mph winds. This unit passes the 12 volt mark at just 150 RPM. The “Hyper-Spin” rotor we sell is a good choice. 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 Low RPM 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, New Steel Shafts and New Rotor Pole Shoes. Replacement bearings and parts will be available for years.
  • Built-in rectifier. (DC output is unregulated)
  • This unit is perfect for direct drive wind turbines in areas that only see 5-15 Mph winds on average.
  • Not recommended for motor driven use. Please select our DC-512, DC412, DC-500 or DC-400 models for use with engine driven applications.
  • 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 150 RPM and the voltage keeps going up from there.
  • Produces 15 Amps into a 12 Volt battery at 2000 RPM.
