- 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
- 5.5 inverter motor around 2000 it is almost so much money electromagnetic speed does not know that we do not produce, but now the basic are the frequency of the world
- Q: 3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
- The inverter operates at constant speed below the base speed, and the output current of the inverter does not change as long as the load does not change.
- Q: 2 pole 0.75 kW motor can increase the speed through the inverter?
- 2-pole motor speed of about 2900 r / min or so, 4-pole motor speed of about 1400 r / min or so, which are in the case of 50HZ,
- 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: 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: What is the frequency of `30 points
- Frequency is to change the frequency ah, see what you are variable frequency equipment.
- Q: Who knows how the frequency converter works
- 2. flat wave circuit In addition, the ripple current generated by the inverter also changes the DC voltage. In order to suppress the voltage fluctuation, the inductor and the capacitor absorb the pulsating voltage (current). In general, the DC voltage of the rectifier is rectified and the DC voltage is rectified. General inverter power supply of the DC part of the main circuit in terms of margin, so eliminating the need for a simple capacitor filter smoothing circuit.
- Q: Who knows how the inverter is calculated?
- The synchronous speed of the two-pole motor is 3000 rpm,
- Q: Does the inverter set the number of poles to match the number of poles of the motor?
- Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. 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.
- Q: Three sets of batteries (540V) DC power supply U / f inverter.
- It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
