- Q:What is the principle and implementation of the inverter?
- AC inverter principle.
It is the first AC current will be converted into direct current, and then use the electronic components of the DC switch. AC power. General power of the larger inverter with a thyristor. And set an adjustable frequency device. The frequency in a certain range adjustable . Used to control the number of revolutions of the motor. The number of revolutions can be adjusted within a certain range. The frequency converter is widely used in the speed regulation of AC motor. Frequency control technology is an important development direction of modern power transmission technology, with power electronics Technology development, exchange frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
- Q:Acer laptop power adapter
- the price is not very clear. You can go online to see the price such as Taobao
- Q:380V motor addition to the inverter, but also how to change its speed?
- Rotary motor rotor series resistance adjustable speed.
4. Change the slip electromagnetic speed (slip motor)
- Q:Do you need to rectify before switching?
- Need to rectify.
The inverter is actually an inverter, which first turns the alternating current into direct current, then switches the DC power with the electronic components, changes to alternating current, and the general-purpose inverter is equipped with a thyristor and an adjustable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
- Q:The parameters of the inverter is 4, 6 motor can be used
- The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
- Q:4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison
- 4-5.5KW inverter made about 1300 or so, the frequency conversion motor about 3000
The same power of the electromagnetic governor + motor about 4000, the price is almost
- Q:How does the variable frequency motor output torque at very low frequencies?
- 1, to improve the slip of the inverter compensation coefficient
2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent.
3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
- Q:What is the application of variable frequency speed control?
- Generally used in the need for continuous speed control of the place.
With the general exchange of motor than its advantages is able to continuously speed.
DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.
- Q:What is the difference between AC and DC frequency converters?
- Inverter air conditioner is relatively speaking in terms of ordinary air conditioning, ordinary air conditioning compression motor using AC induction motor, speed unchanged, 50HZ when the speed is about 2880r / min. The inverter air conditioner is the first 220V, 50HZ single-phase AC into three-phase inverter AC (25 ~ 118HZ, 56 ~ 160), the supply of compressors, through the frequency changes to adjust the compressor speed, so that continuous cooling capacity to adapt to air conditioning Load needs. L inverter air conditioner works: inverter air conditioner compressor by the variable frequency motor drag, the power inverter output frequency changes in the alternating current to the motor, so that the motor speed can be based on the needs of indoor cooling and continuous change, the final compressor cooling capacity To achieve continuous changes in the automatic control. In order to meet the continuous changes in the cooling capacity, the refrigeration system uses an electronic expansion valve, the pulse motor switch valve core, rapid control into the evaporator refrigerant flow. Power frequency changes from the inverter to achieve, as shown in Figure 1: 220V, 50HZ of the mains input, the frequency converter A / D AC / DC conversion, D / A inverter, the output frequency required by the three-phase alternating current, Room switching power supply principle is similar.
- Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
- In the case of other conditions (rated output voltage, plug polarity, etc.) the same circumstances, the rated output current greater power adapter, can replace the rated output current is relatively small power adapter, which is not adversely affected. If the power adapter with a relatively small rated current is used instead of a relatively large power adapter with a rated output current, the power adapter will be "overloaded" and may cause damage to the power adapter.
