Q: Surface grinder can add frequency converter, what are the advantages and disadvantages?: System overviewA. load - constant power propertyWhen the gearbox changes, the torque varies inversely with the speed. Excluding the loss of the gearbox, it has the characteristic of constant power in the full power range.1) the speed grade speed control box has 8 gears speed: 75, 120, 200, 300, 800, 1200, 15002000r/min.2) the main rated parameters of motor, rated capacity: 3.7KW, rated speed: 1440r/min, load characteristics: constant power3) the control mode is controlled by 8 positions of the 8 handles, so that the four clutches can be divided and joined, and the 8 combinations of gears can be obtained, so as to obtain the speed of the two gears.The overload capacity of B. at low speed is strong, and the rated torque will be much larger than the maximum working torque of the load when the drive system is lowered at low speed, and it has a strong overload capacity

Q: I am in control of the equipment: the same mechanical movement, this needs a motor drive, a frequency converter drive. Now it's due to the mechanical location: buy two units of the same motor. Can you use a converter in parallel to drive it? Please point out! Thank you (frequency converter: the power of Schneider is equal to the sum of two motors): In theory, there is no problem with your use. If you have a good mechanical connection, you can do it. If you need high-precision association control, you need to use two inverters

Q: What is the difference between frequency converter and servo driver?: The difference between servomotor and frequency conversion motor:Servo system is a closed-loop control system, the inverter usually works in open-loop control, so in terms of speed and accuracy, and can not be compared to the servo drive.The frequency conversion is only one part of the servo, and the servo controls the closed loop precisely on the basis of frequency conversion so as to achieve better results.

Q: Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: When the high speed motor is driven by a transducer, the higher the higher harmonic is, the higher the output current value is due to the small reactance of the high speed motor. Therefore, the type selection of frequency converter used in high speed motor is slightly larger than the selection of ordinary motor.And if you want a long cable converter operation, this time to take measures to curb the influence of long cable on the coupling capacitor, to avoid the shortage of inverter output, so in this case, the frequency converter to enlarge the capacity of a file or install the output reactor in the inverter output.And for some special applications, such as high temperature, high altitude, at this time will cause the inverter derating, frequency converter to enlarge the capacity of a block.

Q: What does the base frequency 60Hz represent in the inverter?: If the motor chooses a special AC frequency conversion motor, the motor is always marked with constant torque and constant power speed range. For example, Mark 5 ~ 100HZ for constant torque, 100 to 150HZ for constant power, the basic frequency should be set to 100HZ. The fundamental frequency parameter directly reflects the relationship between the output voltage and the output frequency of the inverter. If it is not set properly, it is easy to cause the overcurrent or overload of the motor. For example, an AC motor rated voltage 380V, rated frequency is 60HZ, if the frequency is lower than that of converter 60HZ V/F, a high proportion of the output voltage as high frequency, high output current, at startup, easy to cause the flow. If the frequency converter is set higher than 60HZ, low V/F ratio, the output voltage of the same frequency is low, the output current is low, at startup, can easily lead to the start and overload.

Q: What are the differences between the two quadrant and the four quadrant of the inverter?: The four quadrant inverter can not only drag the motor forward and backward, but also convert the kinetic energy of the motor idle time into electrical energy and feed it back to the power grid. Cause the motor to operate in the generator. Often used in some promotional occasions.

Q: How do two inverters synchronize?: One potentiometer is used to control one of the inverters, and then the analog output of the inverter is used to control another inverter, and a potentiometer is added to the middle of the converter to adjust the proportion.

Q: What's the role of an electric car, the part of a traditional car?: Safe and reliable power on time sequence control.Motor controller, power, according to certain timing control, otherwise it will cause damage to the controller. When the driver presses the motor controller switch button, motor controller is connected to the vehicle controller switching command closed after the precharge contactor, the battery group through the precharge resistor to capacitor charging slow motor controller, when the motor controller detects the DC bus voltage reaches the rated input voltage of 90%, closed motor controller contactor, and cut off the precharge contactor at this time, the main electric motor controller completely to battery group, completed the main electrical power on the process.

Q: What are the benefits of installing economizer in industrial enterprises?: The input and output filter and the DC reactor in the economizer can prevent the harmonic produced by the converter and cause the pollution of the power grid and the surrounding electricity environment.3 、 no disturbance power supply / electricity saving conversion system is beneficial to ensure that the customer load can be put into use quickly when the machine fails, and the normal production of the customer will not be affected. At the same time, the protection function of the economizer is perfect, and it has the protection function of over voltage, under voltage, over current, over temperature and surge resistance.4, reactive power compensation, improve the power factor of the system, reduce reactive power loss.

Q: What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.
