What is the maximum speed of the generator What is the minimum

The maximum speed of JZ is 1800 rpm, and the rest is 1500 or below, and it is not adjusted, and it should be unstable if you change the speed!

What model is divided, the model is different, the speed is naturally not the same, and the model is not the same.

According to the operation limit diagram of synchronous generator, it can be seen that it is limited by the following aspects: the temperature rise (i.e., apparent power) limit of the generator stator winding, the limit of the temperature rise of the excitation winding (i.e., the excitation current), the limit of the rated active power of the generator, the temperature rise of the generator stator end and the static stability limit. 1:

4000 rpm.

The maximum continuous running speed of China's general bearings is about 4000r min, which is the dynamic balance of most motor manufacturers in China.

The test was carried out under the condition of 3000 4000r min, and in summary, the speed of the general motor should not exceed 4000r min.

Problems with high-frequency operation. Because the size of the effective torque of the motor is inversely proportional to the frequency, the frequency is too high, and the effective torque of the motor is reduced too much, and the practical value is not great.

Motor precautions.

Check whether there is any abnormal situation, such as the motor cannot start, start slowly, abnormal sound, etc. During the start-up process, as long as any abnormal phenomenon is found, immediately cut off the power supply and stop the pin machine for inspection. There shall be no other personnel standing near the transmission part of the motor or the two sides of the dragging equipment, so as to avoid injury accidents caused by rotating objects flying out.

The number of continuous starts of the motor should not exceed 3-5 times to avoid overheating of the starting equipment and motor.

It is necessary to carefully check its insulation resistance.

Whether it is qualified, check whether the wiring of the secondary circuit is correct, and the inside of the motor should be dry, clean, and free of debris. Observe whether the fastening bolts of the motor are loose, whether the bearing is short of oil, and whether the gap between the stator and the rotor is reasonable. Fuse.

Contactors, circuit breakers, thermal relays.

Whether the setting value of the protection is reasonable, and whether the wiring and transmission device meet the requirements of the motor start-up bench.

Summary. Normally, it will start to generate electricity when it is higher than 2000 rpm, but today's cars are equipped with regulators, and when the battery power is too low, the computer board will control it, and as long as the vehicle generator is started, it will generate electricity.

What is the speed of the generator on a typical car that can generate electricity after it reaches a certain rotation?

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, I hope this service can be enough to help you. Generally, the engine speed on the car reaches more than 2000 rpm, and the generator will begin to generate electricity, which is equipped with a regulator for the current car, and the computer version will adjust and control the generator in real time according to the state of the vehicle's electric celery bottle for power generation.

What is the minimum speed of the generator.

Normal higher than 2000 rpm will begin to generate electricity, but the current car is equipped with a regulator, when the battery power is too low to roll low, the computer board will control, as long as the vehicle is started to stare at the line generator will generate electricity.

The generator is internally tuned. It doesn't take much to turn....When it is generated, it generates electricity....If the generator indicator light does not go out, it will not generate electricity.

As long as it is rottering, it is generating electricity, when your car starts, it uses the electricity in the battery, and after starting, the generator provides electrical energy to the electrical appliances, and it can send the excess electricity to the battery for storage so that there is enough power for the next start.

As soon as the car starts.

The generator generates electricity! There is no such thing as how many revolutions are used to generate electricity!

After the car starts, electricity is generated.

The machine will generate electricity. When the engine speed is very high, the output voltage of the generator will be very high, and the output voltage of the generator will be the first.

Answer: First enter the voltage regulator (also called voltage regulator, electronic), and then output to the battery after voltage stabilization. Therefore, as long as the engine starts, no matter how high the speed, the voltage of the generator is always very stable.

Motor speed: 2-stage motor: synchronous speed 3000, rotor speed 2600 2980;Class 4 Motor:

synchronous speed 1500, rotor speed 1380-1480; 6-stage motor: synchronous speed 1000, rotor speed ZD900 to 980.

An electric motor is a device that converts electrical energy into mechanical energy. It is the use of electric wires, bridges, local land rings (that is, stator windings) to generate a rotating magnetic field and act on the rotor (such as a squirrel cage closed aluminum frame) to form magnetoelectric dynamic rotational torque.

The motor is divided into DC motor and AC motor according to the different power sources, and most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the magnetic field speed of the stator of the motor is not synchronized with the rotation speed of the rotor).

Precautions for the use of motors:

1. Before disassembly, use compressed air to blow off the dust on the surface of the motor, and wipe the dirt on the surface.

2. Select the working place where the motor is disassembled and clean up the site environment.

3. Familiar with the structural characteristics of the motor and the technical requirements for maintenance.

4. Prepare the tools (including special tools) and equipment required for dismantling.

5. In order to further understand the defects in the operation of the motor, an inspection test can be done before disassembly when possible.

6. Cut off the power supply, remove the external wiring of the motor, and make a record.

7. Use a megohmmeter with appropriate voltage to test the insulation resistance of the motor. In order to compare with the insulation resistance value measured during the last maintenance to judge the insulation change trend and insulation state of the motor, the insulation resistance value measured at different temperatures should be converted to the same temperature, generally converted to 75.

8. Test the absorption ratio k. When the absorption ratio is greater than that, it indicates that the motor insulation has not been damp or the degree of dampness is not serious. <>

Summary. Hello, dear. The faster the speed, the greater the power generation of the generator, and there is no direct relationship between the two.

The speed of the generator is set at the time of design, and it has nothing to do with the amount of electricity generated. For alternating current, the speed of the generator determines the frequency of alternating current, its voltage is determined by the excitation and winding, and the current is determined by the resistance from the power generation to the electrical circuit, that is, the load, because the power generation and electricity consumption are completed in an instant, so the current also varies with the load, and the product of the current and voltage is the power, because the power of the steam turbine cannot change instantaneously, and the change of the current will cause voltage fluctuations.

In addition, it causes a change in rotational speed. The excitation and steam volume should be adjusted to maintain a balance between power generation and consumption. The speed of the DC generator is proportional to the output voltage, and the rated output voltage has been set at the time of design, and the change of speed will cause the change of voltage, so the excitation current can be adjusted to adjust the output voltage.

The rated speed is the specified speed, and the speed that is not allowed to be exceeded; And the maximum speed is its ultimate speed. Rated speed: refers to the speed of the motor at the rated power.

That is, the speed of the motor when it is fully loaded, so it is also called the speed of full load. It is represented by the symbol "n" and is in "conversion points".

The synchronous speed of the motor = 60 * frequency The number of poles is 8 poles: 60 * 50 4 = 750 revolutions, and the asynchronous speed is slightly reduced by about 735 revolutions and the left and right 6 poles.

60 * 50 3 = 1000 rpm, the asynchronous speed is slightly reduced by about 980 rpm about 4 poles: 60 * 50 2 = 1500 rpm, the asynchronous speed is slightly reduced by about 1475 rpm and about 2 poles: 60 * 50 1 = 3000 rpm, and the asynchronous speed is slightly reduced by about 2970 rpm.

The maximum power speed of the engine is different for different key hus. Generally, the maximum power speed of gasoline engine is 5000-8000r min, while the speed of diesel engine is a little lower, at 3000-5000r min.
