Permanent Magnet Alternators

By definition, a Permanent Magnet Alternator is an Alternator that uses moving permanent magnets instead of Electromagnets to induce current in coils of wire.

Permanent Magnet Alternators work well in Wind Generators and Wind Turbines because the wind turbine blades easily attach to spin the generator and produce electricity.

Wind Blue Power offers 4 varieties of Permanent magnet alternators to meet the specific needs of your wind generator. We also offer the proper  External Rectifier Connection Kits so go with these PMAs. Which alternator is best for your wind turbine is based off the average wind speeds in your area.

Each of Wind Blue Power's PMAs features our exclusive 303 Stainless Steel Shaft for the ultimate in corrosion protection and increased power output. The end of the shaft also features a standard thread size of 5/8 x 18 threads per inch for easy adaptation to your project.

The WindBlue DC-512 model is best suited for motor driven applications or very high wind locations when used in a wind generator setup. This PMA reaches 12 volts at 450 RPM.

Your specific wind turbine setup will determine what output you actually see. 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 over 10,000 RPM with ease, but since 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 one of our charge controllers so your batteries do not become overcharged.

The WindBlue DC-520 model, which if used in our Breeze Wind Turbine Kit, is best suited for wind generator applications in areas which average 10 MPH winds or more. It reaches 12 Volts at 275 RPM. Again, your system setup will determine what output your Wind Turbine generates, however,  the DC-520 PMA can handle over 10,000 RPM with ease, but since 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 controller from Wind Blue Power so your batteries do not become overcharged.

The WindBlue DC-540 Model, which is featured in our Lite Breeze Wind Generator Kit, is perfect for use as a wind generator in areas that experience average winds of 5-15 MPH. This Model Reaches 12 Volts at 130 RPM. As with any PMA, your performance will be based off your specific setup. Like the DC-520 model, the DC-540 can handle over 10,000 RPM with ease, but since 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 controller so your batteries do not become overcharged.
