@jeff223344 Both magnets are at an angle because they are so strong that they prevent the motor from turning. So they are angled slightly to allow rotation.
@ddrchild You should wire both solenoids of the motor from the same wire, you should then use right hand rule to find the magnetic field that the each solenoid exerts. In short I think the solenoids in opposite directions should work.
Hi, does the use of glue/tape effect the strength of the current? I want to glue my copper sheets (used for the commutator) onto a wooden dowel but I'm afraid that it will interfere with the ends of the wire attached to the copper sheets themselves. Also if that doesn't cause any problems, am I doing this right? I'm a bit weary of what I'm doing for some reason.
so on the card board tube, you attach the armature?
and on the tube you have solenoid coils wired round?
in btwn. the video is AWESOME.. i have to do ds project for physics. and we were not even introduced to wht the project really is, and d video helped me a lot..!!
@ricky28276 Yes exactly the cardboard tube is the armature, the copper pieces make up the commutator. The tube has metallic screws attached to it and the coils are wrapped around. Thanks, glad this video helped.
i went down to my local power plant and rerouted the electrical grid to get more power, combined with 200 lbs of neodynium magnets i was able to create a black hole the size of a softball...
it sucked my dog in, poor thing, totally worth it though
This is brilliant btw, but I have a question, did you attach one coil to one side of the commutator and the other coil to the other side of the commutator? Because I made the same thing for my project, and it isn't working, I connected the south poles of both the coild to the same side of the commutator and the same for the north poles...and it doesn"t work. Could you please let me know if I did that wrong? Thankyou!
@coolgumball321 the motor should be made using one continuous piece of wire, otherwise it won't work. The two ends of this coil should be connected to opposite sides of the commutator. Also make sure that your winding the coils in the right direction(i.e. clockwise or counterclockwise), or the motor will not work properly.
@anuradhapalanivelu the current is reversed through the process of lenz's law. What happens is that when the solenoid is in the field of the normal magnet, the solenoid changes its pole, to repel away from the magnet. This process repeats multiple times and causes a torque (rotation).
how do i determine the rpm of a brushed dc electric motor? magnet, wire, power. i already know how to build the motor, what i need is the math that goes into it.
@ncranfill rpm means rotations per minute. I am not aware of the formula for rpm from the values of the magnet wire power. There might be one. A simpler way would be to tape a string or fishing line around the armature (tube), run the motor for a minute, measure the amount of line that the motor has rolled up. After you know that find the circumference of the cylindrical tube. Divide the two numbers and then you have rotations per minute. It theoretically be quite accurate.
@Tmac631 the reason i need the formula is so that i can calculate a motor/ generator combination that theoretically will continue to keep its self running without an out side power source. brushed motor with 1 very strong magnet, greater then the rest. the faster it spins the more power produced and the more power produced the faster the motor spins.
@kacado okay i get what your saying what level of schooling is this for because the maximum knowledge i have is grade 12 physics, I'm just starting university in the fall. This sounds like a university type problem? I don't know the formula but the method I created above will give you rpm, then you could use rpm to determine the power of the generator and so on?
@Tmac631 i honestly don't know what level of education the math is in reference to, i am simply searching online for the math and have had great difficulty in acquiring it. i have the math to tell me how many coils of wire i need, but not how much rpm will be generated. btw, the bearings will be magnetic; the least amount of friction possible.
Hello, I'm using neodymium magnets, commutator is copper tubing, my brushes are spare bits of the copper tubing (can see sparks when I turn it myself), PVC pipe armature with PVC ends, and a metal rod instead of a wooden dowel. When i tough the brushes to the commutator nothing happens; when i spin it myself i can see sparks from the brushes, but it stops?
@OneForTheGoodTimes Thanks for subbing, It can be because there is too much friction between the metal dowel and whats holding it. The metal dowel could be getting attracted to magnets, I would highly suggest a wooden or something not ferromagnetic. The next thing is that your magnets are too strong so its creating too much resistance so the motor can't turn, because of the sparks i know its wired correctly. So try pointing the magnetics slightly away from each other so they're not as attractive
@Tmac631 Thats alright. Ok i can try that. Would it be that the wire i'm using for the solenoid isn't working? Im using copper wire and i stripped the ends underneath the copper plates, and im not sure whether the current is travelling through it. Can I send you a picture?
@Tmac631 Ok ill try that. The nails only fix towards the magnets when they get close; it easily spins freely. Could it be that the copper wiring im using isnt working? I stripped the ends to try and achieve bare ends, but the only difference is it gets shinier? Could i send you a picture?
@OneForTheGoodTimes try a metal screw instead of a nail, the core of a solenoid increases the strength of the entire solenoid many times over. wire should be working because of the sparks. another problem may be that your armature is too heavy so the magnets cant move it. i had that problem.
@Tmac631 The nails magnetize with the magnets, I made sure of that? I switched the wooden dowel and nailed two nails to the end so it would sit in the holders, and that was very light; only started getting heavy when I wrapped the wire around it. At the ends of the wires I scraped off the insulation, stuck them under the bits of copper and glue gunned the copper down on the wooden dowel. Copper is pretty thick and hard to manipulate to fit around wooden dowel, could that be a problem?
@OneForTheGoodTimes the copper commutator shouldnt be glued to the dowel? it should be attached to the armature. the commutator should be made up of two pieces of copper not one. and the nails are magnetics but there not strong ferromagnets try screws instead they're a thicker metal and make the solenoid stronger.
Okay so you need to do more research on motors its almost impossible to make this without knowing the theory behind it. The copper is only for ONE end of the tube and is used for the commutator. The screws penetrate the plastic tube only. The copper can be glued or taped onto the plastic tube. Remember the commutator has two breaks opposite to each other.
@Itchier The tube is plastic and I used iron screws, which are magnetic, the core material drastically increases the strength of the solenoid. I just used a screw driver to put them in. Then for the commutator I cut copper tube and glued it to the end of the white plastic one.
@1Philthyz You have to know what your doing. There are many small details that need to be worked out so that the motor runs smoothly. You can tell from the video what materials I used. You can basically use anything you have around. If your confident with the theory you could probably finish it in a weekend.
Great demonstration of an electric motor. I can see that it's been built using things around the house such curtain hangers, cardboard tube and nails. The commutator is built using copper sheet. Great work dude!
