Q:What is the frequency converter used to do, why some motor with the inverter?: Speed control, there are speed requirements of the place are in the inverter

Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total: Is it right? The next manual to see do not understand

Q:The inverter is running independently: . Main working circuit (1) Operation circuit: the external speed, torque and other instructions with the detection circuit current and voltage signal comparison operation, determine the inverter output voltage, frequency. (2) voltage and current detection circuit: isolation with the main circuit potential detection voltage, current and so on. (3) drive circuit: drive the main circuit device circuit. It is isolated from the control circuit to turn on and off the main circuit device. (4) speed detection circuit: mounted on the asynchronous motor shaft speed detector (tg, plg, etc.) signal for the speed signal into the operation loop, according to the command and operation can make the motor running at the command speed. (5) protection circuit: the detection of the main circuit voltage, current, etc., when the overload or over-voltage and other abnormalities, in order to prevent the inverter and asynchronous motor damage

Q:Does the teacher know the working principle of the inverter?: At present the main inverter is Mitsubishi you can go to their domestic sales site to find a specific inverter manual has a detailed explanation Also popular said that the inverter is to change the operating frequency of some mechanical equipment control devices, such as motors, pumps, etc.

Q:Laptop power adapter (no power supply, but indicator light): Notebook power adapter can not charge, but the indicator light does not light the common reasons are: 1, the power adapter is broken or the connector is broken. 2, the power adapter output problem, no output or output is too low, can not give the computer charge. 3, the notebook charging interface is broken, not into the electricity charge. 4, the notebook power management circuit out of the fault, resulting in can not charge.

Q:Notebook power adapter on how to look at power: Power and work voltage power adapter will be identified, you only need to distinguish between input and output on the line, the input refers to the utility power supply support, and now are generally 100V ~ 240V, so you can use in most parts of the world,

Q:Lenovo laptop power adapter side of the feet which is positive: Lenovo laptop power adapter side of the mouth there are clear signs positive and negative, N on behalf of the positive, L on behalf of the negative, it is recommended to carefully look at that you can know.

Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V: 4 volts too little, at least tens of volts

Q:What are the AC motor speed control methods? What are the characteristics of each: Pressure control speed, limited speed range is limited use of variable pole speed, change the motor internal wiring speed, speed is a very speed according to the motor factory set to brand speed to speed control, change the motor input Frequency to speed, are stepless speed is now more popular

Q:What is the application of variable frequency speed control?: Frequency conversion is to change the power supply frequency, thus regulating the load, play a lower power consumption, reduce losses, extend the service life of the role. Frequency translation. Frequency conversion technology is the core of the inverter, through the conversion of the power supply frequency to achieve the motor speed regulation of the automatic adjustment of the 50Hz fixed-line frequency to 30-130 Hz change frequency. At the same time, also make the power supply voltage to adapt to the range of 142-270V, to solve the power grid voltage instability caused by electrical work problems. By changing the AC frequency of the way to achieve the AC control technology is called frequency conversion technology.
