Hi, I got to say I love your site...its very inspiring. I have an old food processing motor that I'm trying to convert to a wind turbine, just to try to learn. After reading your site I want to try and follow your plans for an FP windmill. Its difficult to get an FP motor in the UK. I'm sure there are other motors that will work well, but I'm a noob so for the first project need to stick close to your plans till i understand more! FP have started importing white goods to the UK but not the washing machines, I just phoned them and lied, telling them I bought my washing machine back from NZ with me and I need a new motor. They will sell me the motor, if I have a model number for my washing machine...which I dont! Can some one post a model number for a FP washing machine with a suitable motor in it so I can continue my ruse? 
Thanks, Zane |

Does the Fisher & Paykel IW812 have the right motor? It says it has a revolutionary direct drive motor? |

Hi Zane The food processing motor might work great if your handy. Can you post the nameplate no's. rpm,hp and such? |

Hi Zane, If the food processor has brushes, then it will most likely be a universal type motor. high RPM unfortunately. Gordon. become more energy aware |

Hi Gordon Lets see what he posts back.Jerry's garbogen comes to mind.If it's an actual cupboard type blender thingy then your definitly right. |

Hi lads, Thanks for the replies. This is a tough subject to get to grips with as a noob! The food processor motor is the cheapest crapiest hand held piece of chinese **** I have ever owned, the thing broke in three months, so its just lying there. The motor will certainly be generic, I'm sure it will be high rpm, but as this is my first try it doesnt have to be a good windmill, if it lights an LED I'll be happy. Will a high rpm leccy motor produce a small amount of leccy at low revs, or just none? How about this motor? Do you think it would be good? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=16 0214430879&ssPageName=STRK:MEWA:IT&ih=006 Cheers Lads! |

All, If you want to see this stepper motor you have to remove the space between the 16 and 02, in the link, so it reads =1602144 after you paste it into the address bar. Its a 4 phase permanent magnet stepper motor. Bob |

G'day KE, The Fisher & Paykel IW812 is fine as it has the direct drive 'SmartDrive' motor. I understand this is a current model so the likelihood of finding one at a good price for wrecking is unlikely, though it will have the new de-cogged motor. You Poms are always chasing good motors for windmills. It's an endless search. Perhaps the members of Gotwind's Forum ( Link Here ) will have better local knowledge to help out. Good luck.  was working fine... til the smoke got out. Cheers Gill _Cairns, FNQ |

Hi K E, I had once looked at a stepper moter from an old mainframe hard disk drive. You will find that the power that is developed as an alternator will not be V^2/R. Hi Gill, I have not seen a New smartdrive, but my understanding of the New smartdrive is, a combination of New stator and New rotor. The lack of cogging results from the use of the New rotor on an Old stator with the 7phase rewire. The advantage of the new stator is, it allows for more combinations of rewires. Has anyone checked for cogging on a combination of Old rotor with New stator. I will look at old postings myself, to see if it has been covered. cheers, Gordon. become more energy aware |

Sorry Gordon, I reckon your understanding is incorrect. Admittedly 7 phase reduces cogging by spreading out the cogging drag more than 3 phase, but reduction of cogging is factory built into the new motor by changing the stator pole faces to domed instead of flat and in the rotor by chevron shaped magnetic zones instead of rectangular. The reduction of drag in the 7 phase combo can mostly be attributed to the new rotor. I think Gizmo & BruceDownUnder did a post on this when they first became available. was working fine... til the smoke got out. Cheers Gill _Cairns, FNQ |

No worries Gill, I guess that oscilloscope traces of voltage outputs might show which component caused what. I will probably get away with no mods on my F&P. At the moment it is a balmy 39.9C and not much wind. Solar contributing majority of RE. SA is certainly frying at the moment. Gordon. become more energy aware |
