Sheeesh it has been a long time since I last updated my blog. It's not that I never think about doing it but more like "Damn I'm too lazy to do it right now. I'll do it tomorrow. Besides its oven hot out and I'm not quite done on one side so I'll go flip myself over and finish cooking". Texas is a very nice place; for the most part the people are very friendly. Which in some ways shocked me a bit just because Ft Worth/Dallas is such a big place, and the people have to deal with more assholes then not? Right now it's 93o out side. I just got back (home) around 1pm today because we couldn't do anymore work over at Robbins Engineering due to a fucked up Eddy Current Drive. They have to tear apart the roof of the structure the press is in just to take the Drive out so we can strip it apart and start replacing bearings and shit. And I sure as shit wasn't up for that in this heat. Yesterday we spent 12 hours over there in the heat sweating our ball sacks off. Which by the way brings me to say that I believe I have become accustom to the heat now? After spending 12 hours sweating like a pig I never blacked out once! lmao. Anyway, we couldn't do anymore to the unit at this time because we need to run the press to properly calibrate it. But if the Drive is fucked you can't run it to long because the Amps start to get to high and shut the unit down, because of bad bearings causing too much friction and the circuitry for the drive has to up the Amps to keep the fly wheel spinning at a constant speed. The Eddy Drive is only rated for 30 Amps max. And at the point the unit shuts down the Amps reach 97.2, so it shuts down. Kevin and I both are deaf as hell so we end up repeating our selves to each other, each time yelling a little louder. haha. Kevin is shocked at how much "common" sense I posses. I don't know if I have common sense or not? I know I didn't go to school to learn what I know, I just know what I do because ever since I can remember I've taken things apart to see what makes them work. I learned about electro magnetisms at like age 6 or 7 when I first got a battery powered car. It was one that if you never had batteries in it, but pushed the car to spin the motor the lights would come on. I thought to myself, "Ok, so if this thing ain't got batteries in it how do the lights come on? I'ma take this thing apart and see!" And that’s where my knowledge started. I may not know the names of the parts and shit, but I can explain in what little language skills I have how it works. But the deciphering of what I said is totally up to the listener. :D I never heard of an Eddy Current Drive before and didn't know how it worked. But when Kevin drew a picture of the clutch assembly of the drive I knew right away how the clutch worked before he even started to explain it. Just by looking at the drawing he made. I was like "Ah, ok cool it's basically like an electromagnetic clutch. It works because you end up using a south and north pole betwixt the clutches to lock them together (even though they don't touch each other, but man if they did touch, KAPOW there goes your unit circuitry)". Here is a quick sketch of an Eddy Current Drive:  Now I may have the poles wrong. To me if you use a n pole and a s pole it would attract to the 2 coils together locking them magnetically. Just remember that the two coils never touch each other, there is always a gap between them. Now if you used two s poles or two n poles they would detract each other (push each other apart, and not pull on each other). Something like this using two n poles or s poles would more then likely be used in devices that required friction free movement, like the new electromagnetic trains they are building. So the above diagram shows two coils floating. One inside the other, when you apply a negative current to one coil, and a positive current to the other you get a north and a south pole electromagnet that tries to attract the two metal coils together. Being as though the two coils are static in horizontal movement, they never attract but instead cause a magnetic lock that works like a clutch/brake. By applying less current to the coils the lock is weaker, apply more current and the lock is stronger. For an example, take two bar magnets and try to put the two ends together. If they force each other apart, or you can't get them together, then you are trying to put two of the same poles together and they force each other apart. Switch one around and they stick together. That is basically how these Eddy Current Brakes/clutches/Drives work. Anyway, I'm exhausted today. Too much heat I guess. I'm going to go and have a nap. posted @ 04:09 PM CST [link] |
