- Q: 65w adapter and 90w laptop power adapter What is the difference?
- In general, notebooks have to use power consumption is to decide whether to use 65W or 90W adapter power supply, but not to say that 90W must not use the 65W power supply, but his power is not reached, it is possible that the machine is using some of the features Can not start, for example, external equipment, power supply, if the original request is 90W power supply, but you are using the 65W power supply, external equipment can not work properly. But some cases do not need external equipment, so choose a small 65W power supply is very convenient
- Q: Will the 75KW4 pole motor can be used to increase the speed of the inverter?
- China's power frequency 50hz, and the motor rated frequency match, blindly by increasing the frequency of the inverter output motor speed is not desirable, will affect the motor magnetic circuit, work is not normal.
- Q: Laptop computer about electricity no electricity, is the power adapter problem?
- To judge this is very simple: 1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem 2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter 3. If the two states can work that is the computer charge management part of the poor contact and other issues.
- Q: Does the teacher know the working principle of the inverter?
- Very basic questions, the principle of fine you go online search, everywhere, I do not like to copy someone else, I simply tell you about: Voltage type inverter Three-phase alternating current to the rectifier module, converted into DC, filter stored in the electrolytic capacitor, IGBT + and - from the electrolytic capacitor to take energy, by the DSP (or other controller) output PWM pulse control IGBT turn on and off, So the output AC, the AC and input AC waveform is very different, so that the inverter is also a source of interference. Current filter in the middle of the filter is the inductor non-capacitance, we are more commonly used on the market and the economic converter are mostly voltage-type inverter.
- Q: Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
- 6-pole motor synchronous speed of 1000 r / min, the actual motor speed is lower than the number, the actual speed is required to 500 r / min, then the motor and passive pulley diameter ratio of about 1: 1.6 or so, and then specific With the inverter to speed up to achieve the purpose, please refer to.
- Q: Who knows how the frequency converter works
- 3. Control circuit Now the basic converter with 16-bit, 32-bit microcontroller or DSP as the control core, in order to achieve full digital control. The frequency converter is the output voltage and frequency adjustable speed control device. The circuit that provides the control signal is called the main control circuit. The control circuit is composed of the following circuits: "operation circuit" of frequency and voltage, "voltage and current detection circuit" of main circuit, and "speed detection circuit" of motor. The control signal of the operation circuit is sent to the "drive circuit" and the "protection circuit" of the inverter and the motor Inverter to take the control mode, that is, speed control, turn control, PID or other means
- Q: Who knows how the inverter is calculated?
- Quadrupole motor synchronous speed is: 1500 r / min, but the actual motor speed will be more than 14 turn.
- Q: The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
- Motor speed formula: N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (s); F - power frequency (hz); P - pole pairs of motor rotating magnetic fields.
- Q: 55 瓩 4 pole motor with a frequency of one hour can save much electricity
- Such as: 55KW motor full load operation, 1 hour with 55 degrees of power (according to the motor power slightly different changes),
- Q: Siemens g120 inverter torque limit what is the meaning
- Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
