With the electromagnets on the stator, they are very easy to cool. You can have a lot of electromagnets on the stator for more precise control. The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the...
Alnico magnets are used in many ways, especially in audio systems like speakers and microphones. Advantages of Alnico magnets include high corrosion resistance, high physical strength (do not chip, crack or break easily) and high temperature resistance (up to 540 degrees Celsius). Disadvantages incl...
What is an example of a superconductor? What are some examples of electromagnets? What is analog voltage? What type of split phase motor operates at synchronicity? What is the voltage of a lightning strike? What is the principle behind the motor effect? What is needed to produce an ele...
This type of semiconductor is also named as hard superconductors due to the reason they lose their superconductivity slowly but not simply. These semiconductors will obey the effect of Meissner but not totally. The best examples of these are NbN and Babi3. These superconductors are applicable for ...
rail gun technology, and the Navy would love to exploit these advantages. The office Naval Research has a great diagram of how a rail gun would work mounted on a ship. It could use electricity generated by the ship's nuclear reactor, storing it in a capacitor to be used to fire the ...
DC motor (BLDC), you put the permanent magnets on the rotor and you move the electromagnets to the stator. Then you use an electronic speed controller (ESC) to deliver electric signals that determine rotation speed and direction [source:Joner]. This system has all sorts of advantages: ...
