Great news! Randy's Workshop has made an agreement direct with Fisher & Paykel to purchase some factory second motors. These have passed electrical tests but can not be shipped as new because of cosmetic defects. They Are, perfect for use as a generator. These are the absolutely latest technology and come with the new 42 pole magnets. I am going to price this first load at $95.00 each plus shipping. If you are interested please send me an email since these may go quick. |

Sales have been good. I've found another source of these motors now that Whirlpool and Maytag both have started using them. The Fisher & Paykel Smart Drive Permanent Magnet motor is comprised of a hub, stator, main shaft, two bearings and a bearing holder. The Stator is stationary and comprised of 42 wound coils. The ends of the windings are easily accessible for re-wiring. Since this doesn't have brushes, when the hub is spun it actually becomes an alternator producing AC current. The picture to the left is from their parts manual. You can call Fisher & Paykel Replacement Parts direct at 1-888-936-7872. Their prices include shipping here within the U.S. But Please contact me first. I should be able to get a better deal for you. |

I've gone ahead and made a page showing how I re-wired my F&P unit. Click on the picture to the left to go there. Or here www.watchtv.net/~rburmeister/smart wiring.html. I thought this might help people to see just how easy (and FUN) these units are to work on. |

Here is a picture that one of my customers sent to me of his F&P powered windmill. I designed the universal mount to accept one or two motors. The mount utilizes a Ham Radio antenna rotor bearing. This bearing is heavy duty designed to allow a large Ham radio antenna to rotate. The clamping bolts allow it to be mounted on a mast from 1-1/4" to 2 inch in diameter. Sorry, I don't have any more of these pivot weldments left. It will be some time before I get around to designing and building a different one. |

Here is a picture of the same windmill from a different viewpoint. Jonathan went ahead and modified my design by adding a disc brake. Pretty smart job. He was not happy with the way the tail pivoted and is in the process of coming up with his own design. I can't wait to see it. |
 |
This is one of my finished prototypes. Here you can see the thrust bearing, bridge rectifier, and spring dampened furling pivot. |

I've got another prototype mounted on my windmill tower, ready to generate power. Now all I need is a little wind. |
