1.5" D Stainless Steel Shaft

[wgatenson04]

I have just aquired a 18" 1.5"D stainless steel shaft, and I was wondering what is the max power (direct drive HWAT)wind genni that I could use that for?  Is Stainless good for genni shafts, or is some other kind of hardend steel used?  Also, does anyone know where I can find larger 3"-4" shafts, or whatever it would take for a 30KW genni?

Although newbie i can assist. Fisher & Paykel washing machine motor used as alternator has a 1" shaft or 25.00mm and uses a stainless steel shaft. Various claims range from 350 - 1000W, where the 1000W needs 1000 RPM according to one claim. SS is a bit harder to machine but perfect for all-weather operation.

The strength is determined by the type of stainless steel (304L, 416 17-4 PH etc.)

In any event a 1.5 OD shaft will be more than adequate to handle the torque,

A thumb rule among the old guys,

whom I know is that the diameter

of the wind rotor axle should

be at least 1/100 the diameter

of the wind rotor. For 1 m

rotor 1 cm axle, for 10 m

wind rotor 10 cm axle.

Stainless steel exists

in different variants.
