Convert Alternator to Brushless Motor

all right you ready I'm gonna give it some throttle Wow impressive impressive hello everyone and in this video I will show you how to take an alternator and convert it into a motor now this alternator I got off of ebay I I bought it used for 20 something dollars things with 23 dollars or so it is used it is kind of damaged there's this little piece right here was broken off and so I will post links in a description if you want your own alternator i'ma post some links for cheap alternators there on you and I put maybe couple used ones up there that are fairly cheap and you can do this yourself looks like they just cut the wire didn't even bother disconnecting let me see if I can get this alright one down alright so that's off I don't know if it's all built in or not maybe the voltage regulators in here and all of this basically has to come off oh okay they come right off with pliers so once you loosen them up they come right off all right well not that I look at it looks like the three coil wires are already here okay I want to interrupt this video by explaining this wiring configuration on this particular alternator as you can see there are three terminals only that are coming from the alternator and they have about four wires each and each coil has two wires that it's using so by seeing four wires coming out for the each terminal we know that this particular alternator is wound in a Delta configuration versus the star configuration which was also called Y configuration so this is a Delta configured alternator and the Delta Delta configured motors normally use more amps and they're little more a little more stronger but they're slower than the Y wound motors and while motors they use less amps less power but they tend to spin faster and they have a faster RPM so so we can and the following video that will do I will explain the type of alternators that there are and and how to know which one you have some alternators have three wires some alternatives of for some alternative six wires coming out of them so and I'll explain the video in the next video Megan I'll explain how to tell and how to wire your alternator for your specific need so as we can see after we take this apart the two copper leads right there that's for the coil in the middle for the stator and these three wires are the only wires that are coming up from the alternator so these are the a B and C then you would plug into the electronic speed control so I'm gonna snip these right off right here and we'll go from there one two three and this is what it looks like so this is where the bridge rectifier is is inside this and this part looks like it has the voltage regulator because of this heat sink maybe I can take that off and we can see what's inside see is it going up for some reason and there goes the deaths right here this is a voltage regulator and the numbers are 46 22 8 23 0 70 I wonder how many amps that is but it has this heatsink that was on it keeping it cool alright so I don't need this anymore someone take that off actually can I take that off yes yes I can I think because this will go back in so the two plastic things will go in those two holes and then this will do here like that I will give it a little snug fit I may need to get some new brushes because these are I mean there's still good that's they got a little bit life left in them but as you can see they're almost gone I think this one went below I may need to see if I can pry that back open so this one went under and this one went over all right and then there was just one screw that held in my place I'll try to screw it to the best of my ability well I think this little plastic piece went over it I may need to snip that off and put it on there take this off okay so I have that off I'm going to set it right there I'm gonna take this this is pretty interesting to look at okay so I just want that piece right there let me see if I can snip it off Massa do it from the bottom let me cut this right here make this this is no longer needed and then I'll just snip it right there I'm open my thumb over big as soon as I clip it it's gonna fly off so I'm guessing that worked somewhat all right so now I will use this as a little gauge to put over to put it over this and then I will take one of these bolts I'm guessing they're all the same huh let's pick a random one and I will screw it on just like that all right it's screwed on okay I think that's in and then this little caps went on like this you'd catch this one side and catch the other snap it right on and it's on there and so this is how you would turn this into a mortar so you put DC voltage here between these two so this far right when we Plus and the one closest to this metal would be the ground would be the negative so the negative right there positive right there and this sends voltage to the middle middle part of the stator and then you would actually control the mortar with these three wires a B and C and so because there's three wires that are sticking out we can already tell that this mortar is wired in a delta okay so I have this 30 amp es e I don't know it may be due small but I'm gonna have these banana clips here and I will put three banana clips on here and I will connect these banana clips to it and I'm gonna connect this to the battery and they'll have this 2.4 gigahertz airplane RC airplane receiver and I'm going to connect this and I will control this es e and try to get this to work let's see let's start with the soldering process now these banana clips would plug into the border and this mortar needs to be hooked up to the battery I have this six six cell 18 whatever 650 cells and I'm gonna be there already fully charged it up I will use these to power this mortar and the coil speaking of coil let me go ahead and maybe connect that wire first before I go one further okay so those are soldered and I'm gonna wrap them around once around that little block just to keep them from getting pulled off okay now we'll put this cap back on now let me show you how everything's well plugged in so this is a is gonna be powered by three cells one two three so I'm gonna put this I'm gonna actually connect this first the stator miss connected then I'm gonna take this cell and connect here I just heard the mortar go and now if I give it power yeah it looks like it's going and that yes he's still called there goes the connections are poor on everything so you got to make sure that everything is connected and it does work good it does seem like alright looks like it's working good let me flip this over all right now I'm gonna connect everything and see how well it runs all right you ready I'm gonna give it some throttle Wow impressive impressive wow that's quite a bit of torque all right and that is how you turn a alternator into our motor so okay so the middle stator part only needs about 3.7 volts I'm not sure what happens if you give it more votes than that you may perform a little bit better it may not try giving it some more now I will give it to cells so it slows it down so looks like the more voltage you put towards the middle the more voltage you need on the outside so I would I would think you would need about 12 volts in the stator and about 48 volts through the ESC but this ESC is a 12 volt ESC so this will not work you would actually need a a speed controller like a 48 volt speed controller I will post links in a description for which ones would work but that's how you would do it hopefully it helps somebody thank you guys
