Small Wind Generator - Rebulid, Relocate and Replace




Well through time, trails and errors. I think I've about got a design that might hold for awhile and to relocate it at my mom and dads.

They have a small solar panel with regulator and batteries that power 2 bright LED lights on their front porch.
I have a phone line running from the wind generator to the voltage regulator with a diode to keep the batteries from powering the motor to the (WG).

Lately we have been hit by some pretty strong thunderstorms with high winds. The wind generator (WG) and furling mechanism has held up very well
So I figured it was time to take down the WG and check out the gearing, chuck and motor.
Everything looked great. Very little wear to the teeth on the gears.

I replaced the kiln dried 1x4 with pressure treated 1x4's.
Made a new front cap, the original cap had been chewed away by various issues.
Added more Teflon grease to the gearing.

I then took down the small older WG at my mom and dads and replaced it with the larger geared WG.

I used the base plate and pipe from the older WG and installed it on the newer WG.

I ran an extra support cable from the mast to the house and then attached the phone line to the cable.

I took apart the older (WG) expecting to find the bearings to the motor wore out from the slight imbalance of the blades, but everything was fine.

    Well, I'm back at it and working up a parts list and inventory and probably will do a whole new instructable

    Update 4/22/14

    Almost a yr had past since i took down the destroyed gear driven generator and replaced it with the low voltage out direct drive.

    The direct drive became disabled around fall of 2013.

    I finally took everything down on 4/21/14. Not sure if I'll put any type of wind generator back up.

    But it has be a fun learning experience.

    I found an old discarded 12volt powered 4-wheeler. The attached image is of the motor and gear housing. It takes a lot of force, but when the red hub is slowly spun by hand it produces around 8 volts.

    Welcome, I have a few questions.

    BTW Sorry for my terrible english ;P

    What is the power source? Is it some kind of car alternator 12v or some home made generator?

    I wonder about similar one based on some alternators to head up water and maybe some place. Who knows... tests first. If it will be possible to heat up something than I will probably make a field of this (cheaper anyway).

    I used a DC 12 volt motor for the generator. check out my newest instructable (design #4) for a higher output generator

    I do not know what I am doing wrong, as I have a couple of old cordless drill motors and cannot get any more than .50 of a volt out of the dc motor at high rpms. The motors test out fine when I hook them up to a power supply, but am not getting nearly the power I am reading about that other Instructable followers are getting. Any idea about what I am doing wrong? Thanks Pat

    your not doing anything wrong. the motors from the cordless drills are high RPM motors. The difficult task is finding an low RPM DC motor. Motors from treadmills or motors from very old "reel to reel" computers.

    The only other way is to do some type of gearing. Like what I did with that one experiment. It was a 3 to 1 ratio and would put out around 12 volts in high winds. But direct drive they only put out around 3 volts in high winds.

    I was told the motors I used are made for those outside / garden "G" scale trains/locomotives.

    Thank you, I will set my sights on finding a gear that fits the drive gear on the motor, they are all the same. I appreciate the help.

    This is some time ago, but still a good read, many thanks on your post, one I'm planning on following up, I made a solar auto door for the chicken coop, which works great... One idea for you to stop all that cable spinning up, put some kind of peg/stopper so the turbine will spin almost 360' I'm sure that would work just fine and not twist your cables up?

    Update 4/12/2013 Roughly 7 months and being out of the state......
    My dad had informed me that after being hit with heavy spring storms and high winds, two of the blades snapped off.
    I 1st thought maybe the PVC had become brittle and broke off at the bolt holes, but that was not the case. The blades broke off beyond the drilled holes.

    Also, during this time the gearing had worn down.

    Using the direct drive from the older wind generator and the 3 shorter blades.

    The 3 bladed / direct drive wind generator is back up and spinning
    in east Mississippi
