The diagram shows four different positions of the coil in an alternator, and the corresponding potential difference produced. The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced. Here, the induced potential difference is in the opposite direction to what it was at B. The ac generator An alternating current ac generator is a device that produces a potential difference.
OHV engines have several advantages over other engines such as:. However, OHV-engines are also more expensive than other engines. It reduces wear and tear, and ensures durability of the engine. The CIS is not an expensive feature but it plays an important role in engine durability especially if you need to use your generator often or for long durations. It contains an assembly of stationary and moving parts encased in a housing. The components work together to cause relative movement between the magnetic and electric fields, which in turn generates electricity.
It contains a set of electrical conductors wound in coils over an iron core. The rotor generates a moving magnetic field around the stator, which induces a voltage difference between the windings of the stator. This produces the alternating current AC output of the generator.
The following are the factors that you need to keep in mind while assessing the alternator of a generator:. Plastic housings get deformed with time and cause the moving parts of the alternator to be exposed.
This increases wear and tear and more importantly, is hazardous to the user. The fuel tank usually has sufficient capacity to keep the generator operational for 6 to 8 hours on an average. For commercial applications, it may be necessary to erect and install an external fuel tank. All such installations are subject to the approval of the City Planning Division.
Click the following link for further details regarding fuel tanks for generators. Common features of the fuel system include the following: a Pipe connection from fuel tank to engine — The supply line directs fuel from the tank to the engine and the return line directs fuel from the engine to the tank. When you refill the fuel tank, ensure metal-to-metal contact between the filler nozzle and the fuel tank to avoid sparks.
The fuel pump is typically electrically operated. Voltage Regulator As the name implies, this component regulates the output voltage of the generator. The mechanism is described below against each component that plays a part in the cyclical process of voltage regulation. Is your business in need of an AC generator or a DC backup generator?
Can you tell the difference between the types of generators available on the market and which one best fits your needs? Here is what you need to know so you can invest in the right backup power solutions for your business. In order to determine which generator you need, you should understand a few things first. For example, how do they work? What is the difference between AC and DC power?
What is dc power? Will an AC generator give you what you need? Any type of generator works by converting mechanical power into electrical power through electromagnetic induction. Electromagnetic induction occurs when an electric current passes through a shifting magnetic field, which allows mechanical energy to be converted into electrical energy.
As one side of the coil moves up through the magnetic field , a current is induced in one direction. As the rotation continues and that side of the coil moves down, the induced current reverses direction. This means that the generator produces a current that is constantly changing.
