- Q: 380V motor addition to the inverter, but also how to change its speed?
- 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency
- Q: The laptop power adapter is burned
- You this situation or the first adapter to try, it is likely that the adapter power shortage. If you change the adapter or so, then your problem is big, there may be your laptop to protect the isolation circuit and the charging circuit is a problem, in the insurance repair is free, if the insurance, and to be afraid of a little fear Small expensive, the adapter to buy a cottage on the line, as long as tens of dollars.
- Q: What is the application of variable frequency speed control?
- Frequency control speed ratio is relatively large, in other words, the speed is accurate, smooth speed. Widely used, the basic works can be used
- 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: My laptop can not use the power adapter, and can only use the battery, how is it ah,
- Depending on your question may be the problem that the laptop's internal lines may be short-circuited 1, you can go to the video online to find the same type of machine disassemble video and then repair their own 2, get to the maintenance of the place to get on nothing
- Q: Fuji inverter motor set the number of poles will not have any effect?
- The number of poles is not the same as the speed is not the same mistake machine can not work or motor coil burned
- Q: Can the inverter be used to control the speed of the DC motor?
- The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
- Q: What is the difference between the collector and the emitter mode?
- This physical structure is intended to facilitate the need for positive enlargement.
- Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together
- Pairs of modules are connected in a phase branch The phase output is derived from the neutral point between the modules
- Q: Please recommend a high performance laptop power adapter?
- See what model you notebook ah, according to your power adapter voltage, rated current to match.
