You would have to spin the shaft at 1550 rpm to come close to the 250
watts. It’s doing about 60 to 80 rpm there? I can’t believe you would bolt
the blade directly to the shaft and not have any gearing step up thought
cross your mind. And actually buy all that stuff and put it together. It’s
a motor as opposed to specifically a generator. There’s a small difference
in the design I believe. The blade has to have more thought to efficiency
than 3 straight pieces of L section junked from just anything. The oil
companies must have pushed this video to the top of the list out here.
great job have you thought about wood blades they are fun to make and work
great.check out my videos if you get time maybe it will spark some new
ideas.keep us updated
The 250 watt figure *may* be an alternate horsepower rating. Many motors
nowadays have their hp rating given in watts (1hp = 746 watts). So that 250
watt figure then translates to approximately 1/3hp. They just can’t keep it
simple! I’d just chalk that number up to Harbor Freight’s marketing moxie
and go with the 1/4hp figure. But on another matter, I would definitely
worry about the thrust loads those bearings are gonna get in this
application.
ehm dear videomaker the motor isn’t underrated! you have to understand that
the Wattage written on motors is the meccanical output power . The amps x
voltage is the imput power consumed by the motor. So you are wrong!
Good question. I have heard that you could, however you need to get one out
of an old car. They galled it a generator back then. You would also need to
gear it because it needs to spin quite fast to produce the desired voltage.
Or at least that is what I know about it. Feel free to check other sources
and find out.
Nice looking motor but you will need exceedingly high rpm(s) to make any
decent energy as a direct drive unit. However, you could use a gear ratio
setup as an alternative.
I have not used this wind turbine for about a year now. I am mostly using
solar panels now. I have extremely cut back my usage of electricity. That
is why I started “Low Watt Living” on Facebook. I’m just trying to teach
others that it is not difficult to have a power backup system in place.
@sciurusniger … It worked fairly well in high winds. i’m currently
changing the blade design. i might be changing it to a Vertical Axis Wind
Turbine. We were running it to a set of marine batteries. Not sure how much
i am getting out of it because the wind gusting here. but it keeps the
batteries charged and we run all of our chargeable equipment off of it.
so…..

you need bigger blades.. so much wind but so slow with no load?

I can still have power even if my solar panels cells are not working catch

Missouri wind and solar has a new dual output permanent magnet wind turbine
motor that does 12 to100 volts dc.

I attached an ohm Meter to it and got power just spinning it with my hand.

Yes, a pulley or gear system should increase efficiency and spin the motor
faster.

Yes I did. But it works fine for my needs. It was just a pet project of

the watts are probably the pure shaft power minus friction from bearings,
ohm losses, heat losses..
