Hi Guys, Im about Two weeks away from commencing my first windmill.I have purchased the book from Ecoinnovation on f&p motors and for any-one delving into these I highly recommend it.How ever I have one question. The way I see it these motors will put out a given voltage at given speeds depending on the configuration you have chosen to rewire it.I cant see how you can wire it for 12volt, 24volt or even 48volt. I just see it as generating a lot higher voltage than that, so do you have to deal with voltage regulation after rectification?. Can some-one kindly advise me on this please. Thanks Maaca. |

Hi Macca The battery acts as the voltage regulator. Without the battery in circuit yes you would need a voltage regulator. Batteries work very well as a shunt regulator, and can handle several 10's of amps. Its over charging you need to watch out for. Once the battery goes over 15 or so volts, its fully charged and any more current will start to cause damage, so we use a windmill/solar regulator to stop over charging the battery.

Hi Thanks Glenn.It all adds up to me now.I remember I made some solar panels from a large lot of disused garden lights with an output of 17.5 volts. I found when I connected it to a battery it dropped to around half a volt above the battery voltage and increased as the battery became charged. So the same thing applies to the wind mill.Yes I will be using a switching regulator on the batteries of the wind mill. Many thanks Maaca. |
