water proofing

[kenputer]

 I have some ametek motors that I'll be makeing wind gennies with and wanted to keep the rain out of them. Would a plastic coating like the kind you can use to cover wrenches with be a good choice,i believe it is called plastic dip or is there a better way. Thanks

Silver muffler tape?

For my savonius based on an ametek I found that it slipped nicely into schedule 20 PVC drain pipe (4" I believe).  Carry it into your local hardware store and see what fits.  

I used a combination of schedule 20 and 40 fittings to encapsulate the whole thing with a threaded clean-out cap on the bottom.  It allows the motor to slide out for service and I hold it to the mast with 2 large muffler clamps over the plastic.  Its been up there for about 3 years so far.

whatever you do decise to do, all you want is a rain-shed over it.  Do not seal the motor (genny) against water.  It will actually condense water in it and then it won't be able to get out again.

This is from experience of many years in the satellite industry.  Lots of that equipment came sealed but got water in it anyway.  Leave the seals out and it was never a problem again!!

Finally, some manufacturers leard that and started leaving things open. . .

There are some things that had to be sealed, but many things lasted longer unsealed, but just under a rain-shed.

I have Hathaway motors and just shot a couple coats of paint on them. This sealed the front and rear end caps and the brush caps. Rubbed axle grease liberally around the shaft and drilled a small weep hole at the 6 o'clock position on the rear to let it breathe and/or drain any condensate.
