Useful properties of generators

 Electric start Most generators use a pull cord to start. however Some models come with a push button battery starter. which is easier to use Batteries are not always included with generators.

Gauge The fuel gauge will show you how. How much fuel does a portable generator have left in the tank? Very useful during long power outages. When you have to turn off the power several times Another useful metric is hour meter which will keep track of how many hours the machine has been working This tells you when it's time for an oil change or other routine maintenance.

low oil shutdown This feature protects the generator from damage by turning it off if the oil level is too low. It is standard for most stationary generators. But many portable versions are included.

Automatic CO Switch Off Newer generators often come with a built-in carbon monoxide (CO) sensor if the CO rises to a dangerous level. It will trip a switch that turns off the generator. according to consumer reports Generators from Generac, Cat and DeWalt all have this feature. Other brands of generators such as Ryobi and Echo have low CO engines to reduce the risk of carbon monoxide poisoning.

Multiple channels If your generator is not connected to your household electrical panel with a transfer switch. You need a generator with multiple outlets. so you can plug in multiple devices at the same time Most portable generators have at least two electrical outlets. And some machines have four or more outlets, depending on that.

dual fuel Most portable generators use gasoline only or propane only. However, there will be the most versatile generators available. Also known as a dual-fuel generator. can run on any machine This feature increases the cost of the generator. There are even three-fuel generators that can run on gasoline, propane or natural gas. But these are very rare.

Inverter technology Most portable generators may experience occasional power surges. These do not cause problems with most appliances. But it can damage sensitive electronic devices. Generators with built-in inverters can solve this problem by converting the generator's alternating current (AC) to direct current (DC), and then back to alternating current. Inverter generators are generally smaller, lighter, and more fuel-efficient. and much quieter than other portable generators. However, they are still expensive and have limited productivity. A typical inverter generator costs about $1,000 and produces just 2,000 watts.

Gasoline generator

 This type of generator, of course, requires gasoline, it will provide a low waste release. It has a sound and then releases carbon dioxide. It is very popular with small generators because it is not very expensive.

Diesel generator

 Diesel generators are very durable engines but come at the cost of selling high emissions as well. Most diesel generators are popular in open spaces because diesel generators have a relatively loud noise but high fuel consumption. Quite economical than gasoline, the weight is quite a lot because the diesel engine is an engine that uses a lot of steel material.

Inverter generator

 This inverter generator is a generator developed from a gasoline generator. Inverter generators have low oil consumption, low emissions, and low noise and quiet. The disadvantage of inverter generators is that. The price is higher than general generators.

Magnetic poles, the part that creates a magnetic field. The magnetic poles are stationary and are attached to the DC generator frame.

 Frame (Frame or Yoke) A frame that holds the axis of the magnet pole and the machine cover. It also provides a path for magnetic fields to provide a complete passage of the magnetic lines. The chassis is usually made of cast iron or steel. Plates that are bent in a way, cylinder, and then welded to hold the joints together. In addition, for large generators, the machine frame is designed to be divided into two parts for ease of transport, with one part being the upper part and the lower part, which can be assembled Machine with knots and screws.

Magnetic pole and Pole Shoes and the tip of the magnetic pole that The rounded arch of the armature axis (Pole Shoes) is made from laminated steel sheets. The pump is the axis of the magnetic pole and Pole Shoes to be assembled into the same sheet by protruding from both edges in front of the magnetic pole. which will look curved The round shape of the armature axis is Pole Shoes Pole and Pole Shoe.

A magnetic field coil is a field coil wound around the core of all primary magnetic poles. by the field windings are insulated With a material such as cotton tape, it is soaked with varnish and dried, then attached to the magnetic pole core. Must be connected to the north and south poles alternately or adjacent poles must be poles of different types.

Commuter The part that serves to change the AC voltage in Armature winding to DC voltage In addition, commuters do function of arranging electricity The commutators are made of copper rods, each of which has a wedge-shaped reamer. for ease of assembly in a cylindrical shape But there will be a sheet of mica in the middle between each tooth. with the size of the working power of the generator, including the voltage between the SECommu The stator is adjacent to the internal structure of the commutator.

Self-excitation type DC generator

 Self-excitation type DC generator There is a principle by the coil. The magnetic field is stimulated by means of DC voltage. from induction of the residual magnetic field inside the generator itself When the armature rotates, a slight induced emf is generated. and will generate electricity As a result, this little current flows through the magnetic field coil, creating a magnetic field. by this magnetic field will help reinforce the magnetic field which is residual at the magnetic pole Therefore, the magnetic field becomes more intense, resulting in induction followed by increased induced emf. more and more

The self-excitation DC generator can also be divided According to the nature of the magnetic coil connection can be 3 types, which will be called The name of each type of self-excitation DC generator is correlated with the way the magnetic field coil is connected to the R winding.

Parallel DC Generator (Shunt DC.Generator)

 The working principle of a parallel self excitation DC generator is that when the magnetic field winding is connected in parallel with the armature winding and the generator output, then the current generator is called. exactly this type that Parallel DC Generator by the value of the electric current Excitation of the magnetic field coil in a parallel DC generator is up. Depending on the output voltage and resistance of the magnetic coil, the excitation current of the magnetic coil is normally controlled to be between 0.5-5 percent of the load current.
