Invented by Michael Faraday, this device demonstrates the basics of electromagnetic force. As the electrical current passes through the conductor (the copper wire), it interacts with the magnet, producing a force that causes the wire to spin. 💡 This type of DC motor is called “homopolar” ...
how to control the electromagnetic noise generated from the electric motorPROBLEM TO BE SOLVED: To provide a method of generating an electromagnetic sound having a desired tone from a motor.伊勢田 充加藤 暁花田 秀人
Photo: The inner of a hub motor is a "brushless" motor like this made up of electromagnetic copper coils. The coils, which remain static, generate a magnetic field that makes another part of the motor (not shown here) spin around them. In other words, a hub motor is a brushless motor...
but i find it much more fun to build my own. there are several types of anemometer to choose from, but i am going to build one that uses electromagnetic induction. normally, we think of electric potential as something you can get from a battery. but you also can get it from induction...
Perhaps not the best motor for raw performance, but you can’t really ask more as they are probably the cheapest worth having motors currently available. These are great if you are just starting out or want to build a basher. It’s also an extremely efficient motor if flight time is impo...
Electromagnetic induction is the key to why a motor like this spins—and that's why it's called an induction motor.Photo: An efficient AC induction motor. Photo by Al Puente courtesy of NREL.How does an AC induction motor work? Here's a typical, everyday AC induction motor with its ...

For our example, the increase in the stator back iron thickness of the electric motor means the frequencies of structural modes F0 and F8 shift to the right. Comparing the resulting response shows a reduction in the resonance peak caused by the 12th harmonic by 4 decibels (dB). This is due...
My goals were simple at first; build a small robot using a preexisting kit from eBay. These kits were cheap, usually less than twenty five dollars, add on an Arduino, a motor shield, a battery pack and the cost was less than fifty dollars. Next, I looked at how I was going to con...
