WindGenKits most powerful and versatile PMA. Perfect for charging 12, 24 and 48 volt applications. Includes Rotor, Stator, Custom Hub Assembly & Mounting Bracket. Great for any application in which you would like to generate electricity. Ideal for building a Vertical Axis Wind Turbine and a Horizontal Axis Wind Turbine. Universal Mounting Bracket is designed for mounting the PMA in a variety of applications.
Rotor & Stator produced by Fisher & Paykel. See the spec sheets in this listing. Center hole of Rotor has been machined to 3/4″ to fit custom hub assembly which supports a 3/4″ steel spindle. Spindle threads are 3/4”-16. Shaft length is 1-1/4″. The stator configuration is 27 poles, 3 phase, WYE connected. The magnet size is 24mm x 36mm x 6mm thick. There are 36 magnets. 12″ diameter. Weight is 17lbs.
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. 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 included with this listing. 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. When using for a wind turbine we have easily pushed these to 1000 watts with enough wind and turbine size.
