Permanent Magnet Alternator

Permanent Magnet Alternator

PMA


We make our PMAs 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 and 24 volt.

The PMA as pictured above is set up for direct drive use, just as we use it in our wind generators. If you need the fan and pulley attached to the PMA be sure to add the fan & pulley option below.

If you are using your PMA in an area that receives a lot of rain, snow or salt air we highly recommend have our weather coating applied before we send it to you.

Stats for the PMA are below the pricing information at the bottom of the page.


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.


fan and pulley for pma

You can purchase the PMA with the pulley if you need to gear your system. Simply add the purchase of optional cooling fan and pulley. This option is only available with the purchase of a PMA because we do not add any shipping cost to the purchase price of the fan and pulley kit. We will install the cooling fan and pulley on the PMA for you before we ship.

Optional fan and pulley kit to be purchased with and shipped with the PMA, if purchased seperately you will need to pay an additional shipping fee Price: $10
