Q:How to choose frequency converter?: 3. when the load is large, the braking unit and the braking resistor should be selected simultaneously.4. check the motor nameplate current rating (no nameplate rated current). The rated current of the inverter is greater than the maximum running current of the motor

Q:What's the frequency converter for? What does it look like?: The inverter is mainly used in industrial equipment, such as power plants, water plants, water supply equipment, large pumping station, it is basically a cuboid, a digital display control panel; and in the English show types into the universal type, fan pump type, vector control, different types should be used in different working conditions, voltage grade from 220V-10 million volts.

Q:How does the frequency converter change the voltage and change the speed of the motor?: The inverter does not change the voltage to adjust the speed of the motor. Under the premise of constant voltage, the frequency of the alternating current is changed to adjust the speed of the motor. Typically, at the frequency of 50Hz, the synchronous speed of the quadrupole motor is 1500 rpm, and if the frequency is increased to 60Hz, the synchronous speed should be 1800 rpm; if it falls to 40Hz, the synchronous speed should be 1200 rpm. In the limited frequency range, the power is constant, the higher the speed, the smaller the torque, the lower the speed, the greater the torque. Formula for speed calculation (Rev / min):60 seconds * / log polar frequency. The middle pole of a pair is 2 poles of 1 pairs, i.e., the quadrupole motor is 2 pairs of magnetic poles.The frequency of the converter is stepless, continuous and adjustable, so the speed of the motor is continuously adjustable in a certain range.

Q:Can 220V use frequency converter to drive three-phase motor with 380V?: If it is a star connection instead of a three phase 220V AC input, will the efficiency of the motor be reduced? Can you achieve the efficiency of the original motor 380V?

Q:Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?: The electronic governor for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the output power supply for power has not changed, so the speed is not a kind of energy-saving control methods, such as the electric fan like for home.

Q:What is the difference between inverter energy consumption braking and motor energy consumption braking?: A direct current is generated in the stator winding so that a fixed magnetic field is generated. At this point, the rotor cuts the magnetic field lines in the direction of rotation, resulting in a braking torque. Because the braking method is not like regenerative braking (using frequency converter), the energy generated by braking is fed back to the grid, but the energy is dissipated by the motor alone, so it is called energy consumption braking. The utility model is also used for braking by direct current in the stator winding, so the energy consumption braking is called DC injection braking. By using the backward switch Q to return the point voltage back to the grid, the armature current will become a copy, and the current will be of the same magnitude, resulting in a great braking torque of the motor, which will stop the motor.

Q:What are the basis of the frequency converter to choose?: 1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。3. when the load is large, the braking unit and the braking resistor should be selected simultaneously.4. check the motor nameplate current rating (no nameplate rated current). The rated current of the inverter is greater than the maximum running current of the motor

Q:What is the working principle of elevator frequency converter?: Elevator inverter is generally voltage type AC DC AC converter. The basic construction consists of three parts:1, rectifier circuit, alternating current into direct current2, DC bus, energy storage link, the completion of reactive power exchange in the link, the inverter can obtain higher input power factor.3, inverter, DC inverter to variable frequency and amplitude of alternating current, so that the motor work at different speeds.For detailed transducer principles, see attachment.

Q:What is the over-current of the inverter?: The reason of the frequency converter itself:?1, parameter setting problem: for example, the acceleration time is too short, the PID regulator's proportion P, the integral time I parameter is unreasonable, the overshoot is too big, causes the frequency changer output current oscillation.?2 、 frequency converter hardware problem:

Q:I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: Solutions to interference caused by electromagnetic radiation:1. access reactor2., the correct grounding - grounding wire as close as possible to the frequency converter, the principle of power lines, frequency converter for the ground wire must be usedThe ground wire is separated from the other equipment, and the earthing of all the equipment must be avoided before grounding.The earthing terminal of the frequency converter can not be connected with the zero line.3. access filter.4. reduce carrier frequency.
