F & P shaft size & hub mounting
« on: June 07, 2014, 07:21:55 AM »
Hi. I currently have (had untill yesterday) a small 150w hand built stator and carved blades wind mill. A Storm yesterday cracked two of the blades. I think my tail was too heavy so it did not turn out of the wind.
It took way too long to build the last one so I thought I would go down the f&p route.

New to f&p drives, I have ordered a F&p drive from the usa. I cant get hold of a shaft or its bearings as I live in the uk. Rather than me trying to reinvent the wheel, I thought I would ask for your help as I am sure someone else would have had the same problem.

1: Is it possible to drill out the rotor spline and fit a smooth shaft. Then use pillow block bearings. Mounting the rotor to a steel disc welded to the shaft?

2: any ideas on mounting the blade hub onto the smooth shaft.

My location is exposed to the prevailing westerly winds so get very high average and peek wind speeds.

Thanks in advance.
Dave

Please have a look at the forum called thebackshed (Australian), this is a specialised F&P forum while Otherpower is more into axials. Thebackshed deals exclusively with F&Ps, seeing they used to be a New Zealand based company before they moved to another country.

David, that link would be http://www.thebackshed.com/windmill/Contents.asp#2 .

Domi, are you saying the F/P machines are not axials? Curious what difference that would make in his question, since it is not so radical a difference as Vertical axis and such.

The F&P gen is a washing machine motor with magnets arranged to fly around the copper in a cylindrical shape.

Perhaps we could make a shaft for you
