Hi all, Thanks to Gob & Glen for your intrest. 1 I do have the original controler (Lt biue ) ingood working order, but have no idea how to make it work for me. 2 While working on a VAWT, I realised the old washer would make a great honey extracter if I could control its speeds & direction,hence the forum topic. Any ideas on the subject would be great. Thanks Grrr. I can change it. |

I would give up on using the standard F&P controller, it's all controlled by a microcontroller and cant be fooled. Been there, tried that. What I havn't tried, but I think could work, is a RC brushless motor controller. They are cheap enough to try out, and should work in theory. http://www.myshopping.com.au/ZM--1213866790_MYSTERY_12A_RC_B rushless_Motor_Electric_Speed_Controller_ESC_Blue http://www.ebay.com.au/itm/Mystery-30A-Brushless-Motor-Speed -Controller-RC-ESC-/150583585492 Glenn The best time to plant a tree was twenty years ago, the second best time is right now.

Hi Glenn i tried a model engine controller but the only work on low voltage so that would require reconfiguration the F&P motor to lower voltage unless you use them as a driver for higher voltage fets, a bit beyond me I think. All the best Bob Foolin Around |

Hi Grr44, Welcome to the forum.The honey exstacter is an interesting idea.My guess is you will spin the frames to exstract in one direction,then reverse to exstract the other side,without having to take the frames out to do both.What safe rpm range do you need?One high cost that has crept into the apiary industry is the use of stainless steel recepticals for food handling which has greatly increased the cost of exstracters,so there should be plenty of room for innovation.It's a tuff industry at the best of times,but vital.After all no bees no food!Cheers Rastus see Rastus graduate advise generously |

Guys, as it turns out I have a stock F&P and a single phase in , 3 phase out inverter sitting on the floor in my back shed ans my mind has been pondering using both to re power my lathe. now that you have raised the issue I will couple the two up on sunday and report back. ps. anyone now the horsepower and rpm rating of the stock F & P Rusty |

Good to know they work at least Bob. Yeah I figured you would need to reconfigure the stator for lower voltage, but its the same technique we use to use them for windmills so its pretty easy to do, just takes an hour or so. Rusty the F&P washing machine has a spin cycle of about 1000RPM or so I've been told. As a motor I would expect maybe 800 to 1200 watts, not a lot, but it is a washing machine motor after all.

Hi all, Thanks for the responces, I am learning quick about jumping in too deep. I like the ideas. The high speed of the extracter is 250-400 ruffly. Low speed 90-150. Extracter is for home bee keepers (plastic). Low volts for RC control, would 12v be ok, how many amps will it handle? Grrr. I can change it. |

Hi Grrr44, I think you are in the ball park for rpm,I thought that 500+ would probably destroy the comb.Some of the vawt builders have cut gears out of plastic cutting board material,they seem a bit noisey but work Ok.Reduction gears usually make it easy on motors so you might go for 2.5 drive to 1 driven for high speed and 10 drive to 1 driven for low speed.the motor would last nearly forever.Others may be more specific about gear profile and size.I hope this helps.

finally got around to testing the F&P AS A THREE Phase motor, see video http://www.youtube.com/watch?v=4wlkFXEzA6g&feature=player_pr ofilepage I was expecting it to go faster but I realised this expectation was based on std industrial 3 PH motors. The speed control was very good, right down to 1 Hz. My VSD would only go to 30Hz so it wasn't a good test(I will have to do some reasearch into this). I didn't have any meters at home that day,so I don't have speed or current readings. I will do this test again with tacho an clamp meter. I did get some magic smoke out which suprised me! (interestingly my reaction to the smoke was to immediately turn up the speed to get air flowing over the coils, then I realised how stupid that was!!!. I turned it off ans let it cool down and checed that it still ran, all OK!) Rusty |

Looked very interesting, but what was causing that high pitched squeal? Would drive one nuts eventually. |

Sounds like lamination or coil vibration Where did the smoke come from? Are the 3 phases wired the right way round? Will it squeal with only one phase wired in? |

Have a look here this guy has come up with a very successfull way to use the F&P motor to drive a small electric vechile. F&P EV There are only 10 types of people in the world: those who understand binary, and those who don't. |
