 Okay this motor does not work. Let's see if we can fix it. Let's get a picture of this before this sticker disappears. 36 volts, 4.15 horsepower, 2300 rpms. What do you get? Revolutions per minute. So it'll spin 2300 times every minute. So I put some electricity into this motor and it did not spin, but some electricity was going through because on my little power supply there it said like two amps which means it's probably getting electricity through the coils that don't move but no electricity through the brushes to the spinner part. Does that make sense to you? Yeah. Okay. This spinner part's called the rotor and this the not spinning part is called the stator. Is that right? I think that's good. It doesn't matter though. Just need to make them work. It's basically two opposing electromagnets. That's all it really is. So this thing has four brushes, carbon blocks. The electricity goes through that into that part down there. So we're just going to check that all of these move and are loose enough. Yeah that one's got good contact. They should be, they're spring loaded so they're pressed against the moving part with a spring and if I can like pull it back against the spring and it moves back easily and it stays pressed against the thing it's probably okay. Spring. Is that good? Those all look fine. Hmm I'm gonna have to start chasing the electricity to see where it's getting to and where it's not. I could check this cable here. That'll be super lucky if this cable had some kind of stupid issue. There's probably something inside. All right let's take off this cable and I don't know we'll just double check it. Wait make sure you don't lose that nut. Keep it right here and take off this little washer. You don't need to do it. You can do it with your hand. Get the cable off. You guys have to be really careful doing this stuff. You don't want to lose these. These are brass. It wouldn't be easy to replace. Okay we got some little labels here. We have four contacts. We just had the wire going across here. So this says S1, S2. So I think those are for the stator which is the part that doesn't rotate the electromagnet that just is in the housing. And then A1, A2 I guess that's armature. Is that what it is? Anyway I'm pretty sure this is the electricity that goes into the brushes which would make sense. It's on the piece where the brushes connect. So this goes into the brushes. So if we check the resistance across here electricity should be able to flow pretty easily. And if we check it across here electricity should be able to flow easily. Presuming you know this is just connected to the electromagnet coming back and this one goes through the brushes to it's a the turning electromagnet and comes to here. Right? So if we check across here and across here they should both have very low resistance like electricity should be able to flow through them. We can use our little tester for that. I'm gonna check if the screen isn't brighter. The camera might not be able to see it. Whatever. Okay let's check the resistance. Right now it's giving like a 1 and not really any numbers because it's like sort of like an error. Like the resistance is higher than it's measuring right now. So connect one to here and one there and it's the resistance should go way down to like you connect that one. Okay so the resistance went down to like like to stop moving it yet. Yeah it's like basically zero. Okay now check the other one. Okay well that one's going down too. So that one is a little bit more resistance than the other one but that could be where you're holding the thing. Anyway it'll push it push the point right in and make sure you get good contact. Yeah you know just try to keep it steady and it takes a second for the number to show up here. Yeah it's like all right so electricity is getting through here and through there. So what is the problem? I wonder if maybe my power supply just doesn't have enough electricity to turn this motor even a little bit. So maybe I need to connect it to the house power for a second. The thing is well that the house power is 24 volts so I mean it's not going to turn this at 4.5 or 4.15 horsepower because it's 36 volts but with a lower voltage it'll still be like two horsepower or so. So I'll just want to touch it for a second I don't need a two horsepower motor going crazy in the house. I have to hold it real steady. All right let's go touch it to the house power and see if that turns it on. You want to screw that back on although you know what? Whenever I take something off and put it back I like to clean it first so let's get off a bit of this corrosion so it'll have better contact. So it's shiny now so that'll touch that shiny part and electricity will go through easy. So you want to get this part because this part touches there right? So you want the part that's touching. You know I'd rather not connect this to the house power. I'd rather go out and connect it to one of the boats. Yeah let's do that. Let's screw that wire on there. The way this kind of motor works is you put the electricity in and this goes across the brushes which gets the electricity into the middle part the spinning part. Electricity comes out here goes through here into this part which makes the electricity go into the the housing electromagnet and then comes out here. So with this wire here the electricity goes through both things and energizes everything. All right this thing should have some electricity up here. Let me just flip this. It definitely has electricity it's making some sparks. What is wrong with this motor? All right electricity is flowing through everything because it's getting all the way through. You know that because it's sparking. We're just getting no spinning now. All right we're taking this whole thing apart. All right first just take all the wires off and then we'll pull. Yeah find whatever in here fits this and that pull those out. It starts not crashing. All right see you go this way it's not making the clicks out because it's turning it because there's not enough resistance to make it do the thing. So it's nice and loose that you can just pull it out. All right keep that with those things. Okay get this one so it gets really loose. Yeah hello we might need you to go and make noise because it's 130. This one this one I broke a few years ago I actually made a video about replacing it. No they're not magnets they're they're graphite like you know like what's in a pencil yeah it's like a big block of pencil lead basically more or less not exactly. Now when I put these back together I put some Vaseline to see if they would be more you know if they would lubricate them but I think you really just want them dry and end up wiping out the Vaseline. Anyway those seem to be fine. Bearing in there looks good this part where it goes touch it's a little dirty but it looks fine. All right let's go have some lunch before your brother and sister go crazy. She's gonna work on this don't you? This thing all looks good. I cleaned off this a little. Bearing seems good. I don't see any broken wires in here or anything these wires are huge though I don't think they'd have a problem. This looks just like it's all right. I have to double check make sure everything's still connected but it looks good. And this guy here looks good too. I'm going to double check all the connections make sure electricity is going right through out to this one but I already checked that so it should be fine. I think what I'm probably gonna end up doing is just clean everything really well all that and all that and put it all back together and maybe while I'm cleaning it I'll notice something and you know put a bit of oil on things to make sure it doesn't rust or anything. So yeah clean it oil it put it back together see if I noticed anything. Honestly a lot of times when I do things like this and I'm trying to repair something like probably like three quarters of the time I take something apart I clean it put it back together and then it just works like and I'm not even sure what I did so yeah like a four and a half percent chance that works. Okay let's take the black one and the red one. Is that positive negative? Yep. If you walk so fast but it should turn it. Maybe it's trying if it doesn't have enough. Just mess with your wires. Let me see that. I am gonna do something you guys are going to want to back up for this. Whoa! I better not do that too long on this thing. I still got three lights. Was only a few seconds but yeah I think that is the lumber mill motor. Yeah. I don't want to plug it into the drill bitters for very long. Tomorrow though we can take it back up to the boat and plug it in over there do a real test. But I'm convinced it works. It just went for you know a second but everything looked like it was doing the right thing. Yeah. I needed some cleaning. Yeah.
