Permanent Magnet Alternator

These PMA's have been made from remanufactured GM alternators. They each have a very strong neodymium magnet, specially wound stator, new bearings. These are the PMA's that we use in our Mallard systems and have such wonderful results from. This PMA is specially made to work with low RPMs which makes it ideal for wind power. We can build these in 12, 24 or 48 volt.

Stats for our PMAs

Testing is done on a drill press as high as it will go. We cannot get higher RPMs because it bogs down the press at this point. Testing is done with a full load and is not actual battery charge.

12 volt PMA testing

  24 volt PMA testing

As with any wind generator take ALL safety precautions. Only work on putting up your wind generator during low or no winds. Use at your own risk.

Quick Charge PMA-

This PMA is specially designed for higher RPMs and is to be used with a gas or diesel engine for quick charging your battery pack. Thicker stator windings and permanent magnet combine to make a great fast charging back up DC generator. The picture on the left shows how it can be mounted to an old lawn mower engine. Simply hook this PMA up to a 3-3.5HP engine using a 3-1/2" pulley or to a 5HP engine using a 4" pulley. You can use any size of engine, larger than 3HP, by experimenting with the pulley size to get the best results for the engine that you are using. I have even seen people use car and truck engines. If the size of pulley is too big, it will stall the engine when hooked to the battery. If this happens use a smaller pulley. Check with amp meter when setting the speed of your engine/pulley system. If you cannot find the pulley at your local hardware store we can direct you to a website that sells many sizes of pulleys. In our testing with a 5HP engine and 4" pulley we got 49 volts (open volts) and 30 amps (in to battery)
Do not run at more than 50 amps so that you can preserve the life of the stator.
PMA is made with thicker stator windings to handle higher speeds. However the higher RPMs required by this system do mean that it will not work well in a standard wind generator application.

We show two different type of engines that can be used.
First, Mike used an old lawn mower. He mounted the PMA to the side of the frame and attached the belt to the shaft that would be used for the lawnmower blades. You can run the belt out through the side or back of the lawnmower through the shoot that usually holds the grass catcher. Or you can cut a hole from the frame to run the belt through.
Next, Mike took an old pressure washer from the shop and removed the pump. The engine was still in good shape so Mike then mounted the PMA to the frame and use a belt and pulley to drive the PMA. You can also use an old mini bike engine.

Both of these work really well because you can easily move the charger. You can wheel the unit right out to your battery pack. Or best of all, you can even wheel it out to your car when you have a dead battery for an instant jump start! No more relying on your neighbor to come jump start your car.

TIP- Use battery jumper cables to attach to your batteries. Cut the ends off of one end of the jumper cables. Attach those ends to your PMA quick charger. Then use the clamps on the opposite ends to easily attach to the battery pack or car battery when you need to charge them.

NEW!!!

From Mike's Windmill Shop

Buss Bars for easy connections

We are now offering an easy way to hook all of your wind generators and solar panels in to the same battery pack. This system takes the confusion out of battery pack wiring. Follow our easy to use instructions and hook up your wind generators, solar panels, batteries, inverter and even diversion loads straight to the buss bars. Do be sure to mount to a non-conductive surface such as wood posts or insulate if you do need to mount to a metal frame. 

The great thing about this system is that there is room for expansion. As you add more wind generators, solar panels or batteries you have space to connect them to your existing system.

You will receive two buss bars, one is for the positive connections and one is for the negative connections. Each bar is 36" long. You are purchasing the metal buss bars only. The picture with battery cables connected is for demonstration purposes. The cables are not included. You can purchase the battery cables at the local auto parts store. You hook them up to your own batteries.

If you are using 6 volt batteries let us know and we will provide the correct instructions.

Blades - These blades are specially constructed of carbon fiber with an aerodynamic design. They have been tested in over 100 MPH winds and perform well.

Each set comes with a hub to attach the blades to your system. The 6 blades make a 59" diameter with the hub.

As with any wind generator take ALL safety precautions. Only work on putting up your wind generator during low or no winds. Use at your own risk.
