than by ordinary phase networks.This is the case,for example,for synchronous machines,synchronous motors and generators produce a positive sequence internal voltage and have terminal impedance.For reasons which are beyond the scope of these notes,the impedance to positive sequence currents is not the...
act as a primary source of electric power, operate as part of a larger integrated system, or backup an alternative DC source. Induction motors are used extensively throughout industry because they are relatively simple and inexpensive to build, operate, and maintain. Induction generators are[...

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...
It will require more investors, more supporters, and more true believers in hydrogen to make this work. “Many, many, many more boats,” Erussard said. Truck stuff But also trucks — which General Motors knows a thing or two about. Especially the leviathan-sized ones that are big ...
As we can see, the diesel generators (shown 4 in number) supply 3-phase high-voltage power to the HV busbar rated at either 6.6kV or 11kV. There are different voltage demands on cruise ships according to the equipment. AC chillers, propulsion motors and tunnel thrusters typically have a ...
motors are able to assess those components’ health by looking out for thermal and vibrational telltales of mechanical defects. They can also watch the condition of the track. Several countries’ railway networks make use of them to varying degrees, including those of America, Australia and ...
Unfortunately, it didn't work. Although such generators and motors are very efficient, they still have electric losses in the resistance of the wires, and there is friction in the shaft bearings. Even when the people doing the experiments got the generator-motor unit to run for a while, eve...
SlashGear readers likely recognize ACDelco as a manufacturer of auto-related products such as belts and, in particular, batteries. In fact, ACDelco is owned by General Motors. But the company also produces well-regarded AA batteries for general consumer use. There's not a lot of test data ...
