What are the main structures of small generators?

There are many types of generators, but car generators can currently be divided into two types, one is DC generator and the other is alternator. Since alternators are superior to DC generators in many ways, DC generators have been phased out and all cars now employ alternators. The alternator is generally composed of four parts: stator, rectifier, rotor and end cover.

The function of the stator is to generate alternating current. The stator consists of a stator core and a stator winding. The stator core is made up of silicon steel sheets with grooves in the inner ring, and the wires of the stator windings are embedded in the grooves of the core.

The stator winding has three phases, and the three-phase winding adopts the star connection method or the triangle (high power) connection method, which can generate three-phase alternating current.

The function of the rotor is to generate a rotating magnetic field. The rotor consists of a claw pole, a magnetic yoke, a magnetic field winding, a collector ring, and a rotor shaft. The rotor shaft is pressed with two claw poles, each with six beak-shaped poles, and the cavity of the claw poles is equipped with a magnetic field winding (rotor coil) and a magnetic yoke.

The collector ring is composed of two copper rings insulated from each other, the collector ring is press-installed on the rotor shaft and insulated from the shaft, and the two collector rings are connected to the two ends of the magnetic field winding respectively. When the two collector rings are fed with direct current (through the brush), there is an electric current passing through the magnetic field winding, and an axial magnetic flux is generated, so that one of the claw poles is magnetized into the n pole and the other is magnetized into the S pole, thus forming six pairs of interlaced magnetic poles. When the rotor turns, a rotating magnetic field is formed.

The magnetic circuit of the alternator is: the yoke n pole air gap between the rotor and stator stator the air gap between the stator and the rotor s pole s yoke.

Rectifier; The function of the alternator rectifier is to change the three-phase alternating current of the stator winding into direct current, and the rectifier of the 6-tube alternator is composed of 6 silicon rectifier diodes to form a three-phase full-wave bridge rectifier circuit, and the 6 rectifier tubes are press-fit (or welded) on two plates.

The end cap is generally divided into two parts (front cap and rear cap) and functions as a fixed rotor, stator, rectifier and brush assembly. The end cover is generally cast with aluminum alloy, which can effectively prevent magnetic leakage and has good heat dissipation performance. The rear end cover is equipped with a brush assembly, which consists of a brush, a brush holder and a brush spring.

The role of the brushes is to introduce the power supply through the collector ring into the magnetic field windings.

Small gasoline engine generator carburetor structure and working principle.

Generators refer to the mechanical equipment that converts other forms of energy into electrical energy, which is driven by water turbines, steam turbines, diesel engines or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or atomic nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. So do netizens know what are the main structures of generators?

1. The generator is usually composed of stator, rotor, end cover and bearing.

2. The stator is composed of the stator core, the wire-wrapped winding, the base and other structural parts that fix these parts.

3. The rotor is composed of rotor core (or magnetic pole, magnetic choke) winding, protective ring, central ring, slip ring, fan and rotating shaft and other components.

4. Connect and assemble the stator and rotor of the generator by the bearing and the end of the cover, so that the rotor can rotate in the stator and do the movement of cutting magnetic field lines, so as to generate an induced electric potential, which is drawn out through the terminal and connected to the circuit, and the current is generated.

Step 1: Generator. We have to buy a small generator first, the power is enough at 200w, and then our small wind wheel should not be able to carry it.

Step 2: Manufacture the blades. Jujube Qiaoyi chooses an ABS plastic pipe, (not too thick and not too thin, the diameter is 50-100mm.)

Cut it in the middle and cut it into the shape of a fan page. Grind off the burrs of the fan and smooth the fan blades with fine sandpaper.

Step 3: Make a roulette wheel. Choose a round piece of metal or an axle (note that the sheet is slightly thicker.) Make two holes in parallel on it. Then the edges of the metal sheet are sanded smooth and done.

Step 4: Splicing. It is good to bolt the roulette wheel and the blades we have made, pay attention to the direction of the sash page, and do not install it backwards. That would cause the wheel to reverse, affecting power generation. After the fixation is completed, the roulette is covered with a plastic shell to prevent the roulette from rusting.

Step 5: Assemble. Find a piece of wood or iron, fix the generator on it, and then install a speed-increasing machine between the shaft of the generator and the shaft of the wind wheel, and finally connect the two.

Small generators (using small wind turbines as an example) are done as follows:

Tools Raw materials: generators, ABS pipes, metal discs, wood, wires, etc.

1. First of all, buy a generator with a power of 200W and a rated speed of about 400rpm.

2. Then it is to manufacture blades, this master uses this kind of black ABS pipe and slag acorn, which seems to be more common in China, and now the sewer pipes are made of this material. After cutting, it is properly sanded and smooth.

3. Find a metal disc similar to the picture below to connect the generator and the blades, that is, the hub in the generator.

4. Punch holes in the hub, blades and metal discs.

5. Install the blades on the metal disc and hub.

6. Find a hub cover for the hub, which can prevent the screws from being exposed to the wind and sun, and can also play a role in diversion. Beam pins.

7. Make a bracket for putting the generator, just make a wooden one, and then fix the generator with iron wire or iron sheet. Absolutely.

8. Make a connecting rod.

9. Make a tower with water pipes, the bottom of the tower is as follows, and the wires of the generator can be pierced through this hole.

10. Connect the tower and the generator and fix it with a cable-stayed steel cable. A small generator will do the trick.

The practice of small generators is as follows:1. Experimental materials: hand-cranked generator production kit (the core materials include a motor Mingnai, a large light-emitting diode, and several wire gears).

2. Fix the right-angle rod to the bottom of the dust locust vertical retention plate.

3. Install the gears and rockers on the two shafts.

4. Fix the motor to the retention plate.

5. Install the gear rocker to the retaining rod.

6. Connect the light-emitting diode to the top of the motor wire, and shake the rocker to observe the light.

That's how small generators do it.

The generator usually consists of a stator, a rotor car, and an end cover. Brushes. It is composed of components such as machine base and bearing.

The stator consists of a frame. The stator core, the wire-wrapped windings, and other structural parts that hold these parts in place are not composed.

The rotor consists of a rotor core, a rotor pole (with a magnetic choke. magnetic pole winding), slip rings, (also known as copper rings. collector ring), fan and shaft and other components.

The stator and rotor of the generator are connected and assembled through the bearing, the base and the end cover, so that the rotor can rotate in the stator, and a certain excitation current is introduced through the slip ring, so that the rotor becomes a rotating magnetic field, and the stator coil does the movement of cutting magnetic field lines, so as to generate an induced electric potential, which is drawn out through the terminal and connected to the circuit, and the current is generated.

From the perspective of physical structure, the stator and rotor of the generator are two parts that are completely independent and do not interfere with each other, in addition to the drag of a prime mover.

The stator of the generator is the active source, which generates induced electromotive force and current, and under the drag of the prime mover, the active power of the alternating current is output outward, and the amount of active power is determined by the motive force (oil volume, gas volume, air volume, water volume, etc.).

The rotor of the generator is a reactive power source, and the windings are introduced from the outside to establish a magnetic field, and under the drag of the prime mover, the reactive power of the alternating current is transmitted to the outside, and the reactive power is determined by the direct current of the external input (most of which are rectified by the alternating current spontaneously of the generator).

From the electromagnetic principle, the rotor and the stator are precisely linked, the active and reactive power of the generator are output by the stator, the torque of the rotor determines the size of the active power, and the DC current of the rotor coil determines the size of the reactive power.

The structure of the generator is: generator (independent structure), electric (independent structure), machine (left and right structure).

The structure of the generator is: generator (independent structure), electric (independent structure), machine (left and right structure). The phonetic pronunciation is: one by one. The part of speech is: noun. Pinyin is: fādiànjī.
