How to convert an Old Ceiling Fan Motor into a 70W Efficient Single Phase Alternator Generator

    This project goes over the conversion of an old ceiling fan motor into an single phase alternator .You can’t take your standard AC electric motor and spin it and get an electrical current out of it unless you modify it. The ceiling fan motor used here will produce about 70 volts at one amp which is roughly 70 watts. Through a bridge rectifier we can get about 70 watts of power out of it.

    We start by pulling the cover of the fan. Inside we have a squirrel cage rotor in the middle and 6 coil windings around it. The coil windings are placed in clockwise and anti-clock wise directions inside the stator.

    Next we remove the circular rotor from the threaded shaft which is attached to it with help of a vice. We attach the shaft with the rotor through it within a vice. With the help of an extra piece of pipe to give leverage, we press them against the rotor and push it away from the rod and pop it off.

    We are replacing the rotor that we have detached from the shaft with a two inch hex steel bar . It has six sides that matches with the six coils from the stator.

    With the help of one eighth inch drill bit we cut a hole in the center of our hex bar. We put the hex bar through the shaft and fit them snugly around the threaded area.

    We take six one half inch neodymium or rare earth magnets and place them along the the 6 sides of the hex bar. We place them in such a manner that the poles of the magnets are opposing each other. For permanent usage, wrap this with a little bit of tape or glue so that they are held in place securely.

    We place our modified rotor in the middle of the stator and align them such that they fit in tightly. The outer screen is bolted back onto the motor. We can also add second set of magnets to increase the magnetic field of the rotor .This will also bring it closer to the coils on the outside and increase the overall voltage.

    To convert the alternating current generated by our ceiling fan alternator to direct current, we use a bridge rectifier. It has 4 poles, 2 for connecting our alternating current, the other plus and negative for DC power.

    • How to build a Super Efficient Outdoor Wood Stove Heater from an Old Propane Bottle
      This project goes over the build of an efficient outdoor wood burning stove heater out of an old propane bottle and some scrap metal from the scrapyard. This stove has secondary burn system that helps in combustion of any unburned smoke or fume inside .Almost little to no smoke coming from the flue pipe. The first step is to make sure that the old propane tank is empty. We take the valve at the top by removing the valve protector cage. Fill the tank with water and let it sit for a few hours before we drain the tank and start cutting top and bottom. With the help of a hole saw cutter ,we cut 100mm four inch holes at the top and bottom of the tank . The top hole is for the flue pipe to sit in and the bottom hole is for cleaning the ashes out. We also remove the bottom stand too. Next, we cut a hole for the door for the stove. This is cut as high up to the top of the bottle . The door is made of chequered plate piece . We fit a rectangular pyrex dish glass piece in the middle of the chequered plate that can withstand high temperature with couple of steel bracket pieces. The glass on the door helps us to see how the secondary burn system is working inside the chamber. The door is attached to a frame through hinges. The flue outlet on the top the tank is attached through a flange piece with holes. The door handle is made of a socket wrench. The wrench is bolted to the plate and a small metal piece is welded onto to the frame to which the wrench is pulled to close the door A deflector plate made of small holes is installed inside the stove on the top . We drill 8mm holes around the top of tank and put dome bolts across them. The deflector pipe sits on these bolts. The deflector plate stop the unburned gases exiting out the flue outlet pipe. This encourages the flame that rises, pass through the deflector plate holes into the secondary burn chamber that helps in better combustion. The secondary burn system is made of stainless steel pipes .The air intake section is long enough to get the air coming in to get super heated and move into two sections filled with holes. Since not all gases from the wood combust from the primary air intake, the secondary burn pipe ensures that the air gets super heated before exiting the pre-drilled holes and helps burn the unburned gases rising from the fire before exiting the flue pipe. The secondary air intake pipe coming out of the firebox is welded on the top of the tank with a flange piece. The primary air intake pipe that goes under the door frame is made of a two inch coupler and threaded damper disc. A small metal piece is welded to the coupler with a hole in the middle. The damper disc screws in through the hole that allows us to close and open the intake .
    • DIY Video : How to recycle your Waste motor oil,transmission oil or any waste fuel into 100% Re-Usable Fuel
      Salvage waste motor oil, transmission fluid, old diesel that has water in it, whatever type of fuel that you might be able to have access to, wouldn't it be great to be able to take that fuel and run it in your vehicles and not throw it away? Or have to recycle it, you can recycle it yourself. Well, one of the ways is to filter. But filter material is expensive, and you got to constantly replace it. So I was introduced to this filter. Actually, it's a centrifuge by USfilterMaxx. This is just our initial test where we're going to take waste motor oil, dump it in the top of the centrifuge at spinning at about 3000 RPMs or more. And then we're going to drain and the result will be waste will be sludge in one bucket and clean motor oil and the other that can be mixed with diesel or run straight. In some diesel engines be careful on how you do this, you don't wanna mess up your injectors. But for old diesel engines that are very pretty forgiving, this is a great solution. So again, this stuff will go in my tractor or my old two cylinder diesel generator, but I'm just taking waste motor oil, and spinning out everything to make to make fuel, waste or motor oil has a ton of btu's in it. And mixing it with diesel makes for a very good sustainable solution. This is just some motor oil, nice and black from a friend of mine is changing oil in his truck. And we're gonna start with a two and a half gallon batch and run this through the centrifuge and see what she does with it. So you can see how black it is. Run the centrifuge on start introducing the waste oil. Okay, we're starting to get this filtered oil out.We're just doing a two and a half gallon batch run here. And then we're going to shut the centrifuge off. And the only way to really tell if we did anything was to see how much sludge is left in the centrifuge. That doesn't work until the centrifuge stops spinning because all the sludges is gonna be stuck to the outside wall. The sludge starts coming out.The centrifuge has stopped spinning, everything moves to the center and that's where the drain plug is This is the guts of the centrifuge. When this is spinning, it takes the oil coming in and pushes it out, and it comes over the dam, the clean stuff comes over here, it looks like it never had oil on it. And then that drops in here to come out the clean tube. When you stop spinning, the internal drains here. That's where the sludge is coming. The centrifuge run off a 220 power source. So you will need a generator or grid power to run it, or a pretty good battery bank in an inverter to run it We're gonna take our motor oil that we've just spun in a centrifuge, and we're going to put about a gallon and a half of it in this five gallon jug, and then I'm going to add a gallon and a half of diesel.We're gonna pour some of our motor oil mix and veggie. I mean motor oil and diesel 50-50 combination first. We've added a few cool features to our centrifuge we added a shell and tube heat exchanger made out of copper. So we can take hot water and heat the oil, the stored oil to a point where the viscosity is, is much lower, and it'll spin out a lot cleaner. We've added a little solar direct drive water pump, throwing off a little 20 watt panel, moving the hot water through the shell and tube. We've also added a P-trap to make sure any of the vapors from the hot oil do not escape into the clean oil bucket. They stay in the centrifuge and actually are evacuated out of the sludge side. We use thermo siphoning using a used water heater for the heat .This is free heat, there's no pumps, just thermo siphoning up to this tank and then using the little solar pump to take the hot water off the top of that tank and run it to our shell and tube. So pretty much off the grid water heating, heating lots of water using a thermal siphoning process.
