- Q: Pump frequency converter instantaneous restart and restart the problem
- How the frequency converter works: The frequency converter is a power control device that transforms the power frequency power supply into another frequency by the on-off function of the power semiconductor device. We are now using the inverter is mainly used to pay - straight - cross mode (VVVF frequency conversion or vector control frequency), the first frequency AC power through the rectifier into a DC power supply, and then convert the DC power supply frequency, voltage can be controlled AC power supply to the motor. The circuit of the inverter is usually composed of four parts: rectifier, intermediate DC link, inverter and control. Rectifier part of the three-phase bridge uncontrollable rectifier, inverter part of the IGBT three-phase bridge inverter, and the output for the PWM waveform, the middle of the DC link for the filter, DC energy storage and buffer reactive power.
- Q: Will the 75KW4 pole motor can be used to increase the speed of the inverter?
- The motor speed is relative, the rated speed is the maximum speed
- Q: Laptop power adapter leakage
- You feel, or do not feel is to take the amount of pen? If the feeling after it, then for a, if the amount of pen, then hand touched, it should not be bright. That is a induction, is Virtual electricity, it does not matter.
- Q: Servo control system can give the inverter signal,
- but want two motor synchronization, it should be impossible, the converter does not reflect so fast, and the speed is not so stable.
- Q: Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole
- Motor fever is normal, ah, as long as not overheating on the line
- Q: How does the variable frequency motor output torque at very low frequencies?
- 1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
- Q: Yaskawa inverter reported base blockade what is the reason?
- For example, when you stop the inverter, there will be a signal to the inverter, and then the inverter will base block, cut off the output, the motor will no longer work; when you need the inverter work, There is a signal to the inverter, the inverter to cancel the base blockade, it is normal work,
- Q: The inverter is running independently
- Principle of operation The main circuit is to provide asynchronous motor to the frequency conversion power supply part of the inverter, the main circuit of the inverter can be divided into two categories: voltage is the voltage source of the DC converter for the exchange of the inverter, DC circuit filter Is a capacitor. Current type is the current source of the DC into AC inverter, the DC loop filter is the inductance. It consists of three parts, the frequency power supply is converted to DC power "rectifier", absorbing in the converter and the inverter voltage ripple "smooth circuit." The basic composition of the rectifier unit: the fixed frequency of alternating current converted to direct current. High capacity capacitance: store converted energy. Inverter: high-power switching transistor array composed of electronic switches, the DC into different frequency, width, amplitude of the square wave. Controller: According to the set program work, control the amplitude of the output square wave and pulse width, so that superimposed as an approximate sine wave AC, drive AC motor.
- Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
- 4, high-speed motor: high-speed motor running process will produce a large number of harmonics, enhance the output current of the inverter, resulting in a lot of heat. Therefore, the inverter selection is also larger than the ordinary one gear. 5, explosion-proof motor: In some mines, oil extraction environment, the frequency conversion system is explosion-proof motor, the choice of inverter should use the explosion-proof function of the inverter, and the inverter placed in a safer place. 6, the degree of protection: for dust, wet applications, inverter selection should pay attention to its protection level. Or choose Ampang letter AMB inverter, the fan can also run in the water. 7, single-phase motor: When the scene using single-phase motor, the inverter useless. 8, variable pole motor: When the field using variable pole motor, the inverter selection should ensure that the maximum operating current should not exceed the rated current of the inverter
- Q: Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
- and then use the inverter into three-phase AC, 380 volts almost, Can only use the transformer rose to 380 volts.
