Shunt Generator

!±8± Shunt Generator

Shunt DC generator is a generator whose field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current. Shunt generator is not a good generator to supply your electrical power since this generator has unstable out put power.

Shunt generator's name is taken from the field. In generator there are two types of winding. Shunt field winding and if the generator uses two winding field it is called compound generator. People usually used compound because of the stability in producing voltage and current load.

In shunt generator, amplifier excitation is connected in parallel to the rotor. Initial voltage generator is obtained from residual magnetism contained in a magnetic field stator. The rotor rotates in a weak magnetic field. The stator magnetic field will be strengthening by the resulting voltage, to achieve its nominal voltage.

Excitation amplifier is connected in parallel with the rotor. Initial voltage generator is obtained from residual magnetism contained in a magnetic field stator. The rotor rotates in a weak magnetic field; the resulting voltage will strengthen the stator magnetic field, to achieve its nominal voltage. Setting excitation current passes through the shunt winding regulated by shear resistance. The larger the shunt excitation current, the greater the resulting field shunt amplifier, and the terminal voltage increases until it reaches its standard voltage.

If shunt generator does not get its excitation power, then the electrical power also does not exist. And if the winding excitation is wrong or reversed then there will be no electrical power from the generator. Shunt generator's voltage will drop if the load current is increased. This problem will not be found in compound generator which has two excitation amplifiers. The first amplifier is shunt while the second is series amplifier. In compound, strengthening the series winding will also increase the voltage if the current load is increased.

So, without further ado, let's check out the computers that make the grade.

#10 - Lenovo 3000 J Series: These computers are geared towards families, and they combine the power of AMD 64 processors with the function of a 250MB Hard Drive. Priced at less than 0, these systems clock in as a real crowd pleaser.

#9 - Fujitsu Esprimo C: This is one of the smallest desktops available on the market, and it is also one of the sleekest. These machines can be tailored to your individual needs, and will not disappoint.

#8 - Alienware Area 51 Series: These great looking machines offer unparalleled performance to even the most serious game enthusiasts. The graphics and sound capabilities coupled with the speed of Intel 4 processing make this a must have for those who want a desktop that entertains.

#7 - emachines D5039: Hands down, this desktop is the best value on the market. Emachines is a well repected PC company that has the family in mind, and does a great job of offering amazing products at unbeatable prices. This unit contains everything you need to get started - definitely worth a look (or two!).

#6 - Sony Vaio RB60: This desktop from Sony comes bundled with a lot of cool Sony software, and it also comes equipped with a 17" LCD display. This is a perfect choice for those wanting a great entertainment PC that also handles work and internet. This product is definitely a solid choice.

#5 - Compaq Presario Series: These computers are very affordable and very reliable. Compaq Presario desktops are the perfect choice for families, and come standard with everything you need to instantly start surfing the web.

#4 - HP Pavilion Series: A much underrated desktop line, the HP Pavilion series features dual core processors, which make multi-tasking a breeze. They also offer easy memory expansion as well as some of the sharpest graphic and sound cards in the business.

#3 - Apple iMac: When it comes to music and video capabilities, the Apple iMac desktop is second to none. Macs are quickly gaining steam in the computer race, and with good reason. You won't be sorry giving this one a try.

#2 - Gateway DX310 Series: Dual core processors mean this unit is just as fast as other higher priced competitors. Gateway offers amazing customer support, and also has some of the most generous rebate offers in the business. In addition, they make it very easy to earn free upgrades. Do yourself a favor and give Gateway a look.

#1 - Dell XPS 400: This computer tops our list for many reasons. The only thing you need to know is that it look great, it runs amazingly fast (and quiet), and it comes bundled with a 19"flat screen monitor. All of this for under 00 makes the Dell XPS one sweet deal.

This list of the Top 10 best desktop computers should make buying your next computer a quick and painless process. In fact, considering how great these desktop computers are, you might just find yourself wanting to take more than one home! Have fun!
