For a limited time we are offering our FP-640 PMA for $30 off

FP-640 Permanent Magnet Alternator Wind Turbine Generator

• Our most powerful and versatile PMA. Perfect for charging 12, 24 and 48 volt applications.

• Parts included: Rotor, Stator & Custom Hub Assembly.

• Rotor & Stator produced by Fisher & Paykel.

• Weight is 17lbs and is 12\" diameter.

• Center hole of Rotor has been machined to 3/4\" to fit custom hub assembly.

• Unique robust Hub Assembly produced by WindGenKits supports a massive 3/4” steel spindle.

• Spindle threads are 3/4-16. Shaft length is 1-1/4\".

• The high efficiency of this alternator is from the radial design, iron core stator with a close air gap from the 36 pole permanent magnet rotor.

• No Cogging.

• 4 mounting holes for 3/8-16 bolts. Mounting hole pattern is 4 bolt on a 3.25” diameter circle. Mounts to our standard mounting bracket. See Figure 1 diagram.

• Output is 3 phase AC power at a voltage of .608V per RPM.The output voltage is easily calculated with this equation: V = .608 X RPM. For example, at 10 RPM it will produce 6.08 volts and at 100 RPM it produces 60.8 volts.

• The Stator is rated at 640 watts continuous as a motor.

• The power output depends on the power input and we have easily pushed these to 1000 watts with enough wind and turbine size.

• The stator configuration is 27 poles, 3 phase, WYE connected.

• The magnet size is 24mm x 36mm x 6mm thick. There are 36 magnets.

• See the Fisher & Paykel spec sheets in this listing.

• As an option, you could spray PMA with a clear varnish to help with corrosion when using for a wind turbine.

This listing is for the PMA only. We show a few photos of our PMA on a Vertical Axis Wind Turbine and a Horizonal Axis Wind Turbine. Bracket shown is sold seperatly or can be purchased as a bundle with our PMA at our store.
