I have a question..I seen a induction motor that have no brushes..they said its easy to make and very efficient ..Does this mean..motor with brushes show on this video is obsolete?...thanks in advance.
@straighter100 So if the dc supply was reversed with the positive wire going to the other brush and the negative wire to the opposite brush also the armature would turn in the other direction?????
I found a video that is much easier to understand, this video does not do a good job of illustrating what the commutator actually does. I did not understand it until watching this video:
regarding the field coils, is the magnetic fiel produce by these coils is only on one side (inward) of the pole face?.. how about the other side of the pole face, facing (outward) the casing of the motor?... i just thought that electromagnet produce magnetism on both sides of the iron. ty
"All electric motors that produce rotation work in essentially the same way as a direct-current series motor, which is commonly used to drive electric railroad cars."
That's a bold-faced lie. As an example, the AC induction motor (Which is now the preferred choice for "electric railroad cars") is only related to a DC series motor by virtue of having electromagnets and producing rotation. Other than that, they are very much different.
So this isn't one of the Dizz Vids that I would show the kids. @behemoth2334 didn't you have science class? Or shop class? I made at least 2 simple electric motors in high school. Ya know, wind the wire for the armature, wrap 2 pieces of copper around the shaft and a hairpin or something for a brush? CMON KIDS!
Current is the flow of electricity. The flow of electricity creates a magnetic field. If you've ever played with magnets, you'd realize that they only attract eachother from certain sides, and repel with some force if you try to force them the wrong way. What the motor essentially does is put 2 powerful fields on each side of the rotating shaft to cause it to spin by pushing it in the same way the magnets repel eachother. The magnets in this case are man-made. That's the gist.
I already understand the basics of electricity. It's simple and pretty much confusing-free in my opinion. It's just recently that I started to wonder how electrical energy can be converted into mechanical.
its like saying "the ringed pulley chain transfers momentum from the circular toothed spindle, to the rear cassette" why no say "da chain makes the bike wheel go round!"
@Behemoth2334 You should Youtube the video "Principles of Electricity (1945) - Part 1" and then Part 2 Because understanding the principles will help you grasp this concept.
Basically electricity flows through the coiled wires and there are to magnets north and south. Magnetic fields cause electrons to move or it pushes them away(Causing the wire to move). So pretty much these magnets spin the motor by pushing electrons to cause a force that spins the motor.
DC Motors will likely be used less in many industrial applications because of the power semiconductors that is used in Variable Frequency Drives (VFD) to run induction motors who has no brushes that requires replacement every now and then.
@gibo772000 DC motors were only used where torque and speed control was necessary. So they have been out numbered by AC motors for many years as many applications are constant speed type. The VVFD allows an AC motor to perform the same functions as a DC motor which means that spells the death bell for DC motors except where instantaneous speed changes are needed like in servo apps.
@A7XsUxOrZ You need to understand what the Lorentz Force is. It's a force created by electric current under influence of a magnetic field. Take your right hand and imitate a pistol with it. Your index finger is the direction of the magnetic field, your thumb pointing upwards is the direction of the electric current and the other three fingers pointing to the left is the direction of the Lorentz Force. No apply this to the image above and visualize these forces as arrows, usually called vectors.
ive always wondered how a motor worked, like how you transfer electric energy to mechanical.... i geuss i never thought of transfering electric to magnetic and magnetic to mechanical
