Why we using permanent magnet generator ?

Asked by permanentmagnetgenerator (1points) June 11th, 2014

The permanent magnet generator is a synchronous machine where the rotor windings has been replaced with permanent magnets. This eliminates the excitation loses in the rotor, which otherwise typically represent 20–30% of the total generator loses. The reduced losses also give a lower temperature rise in the generator, which means that a smaller and simpler cooling system can be used.
The temperature reduction in the rotor also reduces the temperature in the bearings, improving reliability by increasing the lifetime of the bearing and bearing grease.

Water, fire, air and dirt
Fucking magnets, how do they work?
And I don’t wanna talk to a scientist
Y’all motherfuckers lying, and getting me pissed
Solar eclipse, and vicious weather
Fifteen thousand Juggalos together
