Q:What is the single axis of the inverter and multi-axis applications
Inverter is the application of frequency conversion technology and microelectronics technology, by changing the motor power supply frequency and amplitude of the way to control the AC motor power transmission components.
Q:Do you need to rectify before switching?
I used to do the frequency of the words to be rectified
Q:Will the motor suddenly stop when the inverter is suddenly powered down?
Generally in the absence of external brake or brake case, if the power, the motor is in a free stop state, uncontrolled,will gradually slow down to 0
Q:Laptop adapter heat
In fact, as long as the power adapter temperature is within the design range, that is, the temperature in the normal range, the general is not dangerous! So why is the power supply hot? What kind of temperature range is the normal range? Switching power supply conversion efficiency can only reach 75% -85% or so. The answer is here. Switching power supply conversion efficiency is high enough, it is still difficult to find a better way to convert. Switching power supply in the voltage conversion, a part of the energy loss, in addition to a small part of the loss in the form of waves, the majority of the way out of the heat. Switching power supply power is missing, the loss of energy is also missing, the power of the heat is also large. This is why the desktop power supply to add a fan for cooling reasons. We may wish to count, a 100W switching power supply, in the use of how much energy loss in the above!
Q:How does the laptop's power adapter open
Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
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.
Q:What is the base blockade in the drive?
After the base is blocked, the power tube is fully closed to protect the power tube.
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: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:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
 Fourth, the electromagnetic speed: electromagnetic speed motor by the cage motor, electromagnetic slip clutch and DC excitation power. DC excitation power is small, usually by single-phase half-wave or full-wave thyristor rectifier composition, change the thyristor conduction angle, you can change the size of the excitation current.
