The yoke is usually made of cast iron or cast steel, depending on the size and weight of the generator. For small generators, cast iron is cheaper but heavier than steel. For large generators, where weight is a concern, cast steel or rolled steel is preferred. The yoke is shaped like a...
AC power allows us to construct generators, motors, and distribution systems from electricity that are far more efficient than direct current, which is why AC is the most popular energy current for powering applications. How Does A Three Phase Four Pole Induction Motor Work? Asynchronous motor ani...
Like the SOFC, these fuel cells are also best suited for large, stationary power generators. They operate at over 600 degrees Celsius, so they can generate steam that can be used to generate more power. The cell uses a molten salt solution as a catalyst that separates hydrogen particles from...
Just as electric motors can be used in reverse as generators, so you can put energy into a Stirling engine and run it backward, effectively removing heat from the heat sink and expelling it at the source. That turns a Stirling engine into a "cryocooler"—a very efficient cooling device. ...
Bearings are one of the most common elements in modern industrial machinery. They connect the rotating part (shaft) to the stationary part (housing) with minimal friction. They allow for the smooth running of machinery ranging from cars and aircraft to generators, conveyors, printing presses and ...
those little machines that cause cell telephones and pagers to vibrate (yes,those are rotating electricmachines) to turbine generators with ratings upwards of a Gigawatt.Most of the machines withwhich we are familiar are rotating,but linear electric motors are widely used,from shu...
With such a high-speed flywheel, safety considerations become hugely important; the flywheel is fitted inside a super-sturdy carbon-fiber container to stop it injuring the driver if it explodes. (Some forms of KERS use electric motors, generators, and batteries to store energy instead of ...
Magnets are also vital components in CRT televisions, speakers, microphones, generators, transformers, electric motors, burglar alarms, cassette tapes, compasses and car speedometers. In addition to their practical uses, magnets have numerous amazing properties. They can induce current in wire and ...
The steam locomotive lasted for about a century, but was eventually replaced by the diesel locomotive, a mighty mechanical wonder that may consist of a giant engine along with electric alternators or generators to provide electrical power to the train. In fact, diesel locomotives have their very...
Electric current first flows out the top of the battery, through the wire and bulb and then returns via the bottom wire. So it always flows in a loop and two wires are needed to connect the voltage source to the load. In this example of a simple circuit, an AA cell forces current ...
