Q:Can the frequency converter 7.5KW take the motor with 11KW?
The inverter rated current 7.5 kW is about 17A, the constant current 11KW converter is about 25A 11KW Oh, no-load current is about 8A, 17A is greater than 8A, so the 7.5KW motor with 11KW is no problem, but you have much load, full of motor current 11KW is 25A, 7.5KW certainly do not move with the! That is to say, you can carry 11KW motors running under light loads. Don't worry, the frequency converter will burn down, because the inverter has overload and over-current protection, it can protect your inverter and your motor from damage!
Q:How does frequency converter realize variable frequency speed regulation?
Frequency conversion means changing the power supply frequency.The core of frequency conversion technology is frequency converter. It can automatically adjust the speed of motor operation by changing the frequency of power supply, and change the fixed frequency of 50Hz to 30 - 130 Hz frequency. At the same time, it also makes the voltage range of power supply reach 142 - 270V, and solves the difficult problem of electrical work because of the instability of the grid voltage.
Q:What is the difference between a frequency converter and a servo controller?
Servo system: 1 servo drives in the premise of the development of frequency conversion technology, the current loop in the internal drive, speed loop and position loop (inverter without the ring) of algorithm operation and control technology is more accurate than the general frequency, but also in the function than the traditional servo many powerful, the main point can accurate position control. To control the speed and position of the pulse sequence controller sends the (of course there are also some integrated servo control unit or by bus communication way directly to set the parameters of position and velocity in the drive), drive the internal algorithm and faster and more accurate calculation and better performance of electronic devices to be more superior to converter. 2, motor servo motor of the material, structure and machining process is much higher than that of the AC motor drive inverter (general AC motor or constant torque, constant power and other types of motor), that is to say when the power driver output current and voltage and frequency change quickly, the servo motor can generate action response according to the change power changes, response and anti overload capacity is much higher than that of AC motor inverter drive motor, fundamental serious differences is two different performance. That is to say, not the inverter can not change the power supply signal, but the motor itself can not respond, so in the frequency of the internal algorithm settings, in order to protect the motor to do the corresponding overload settings. Of course, even if the output power of the inverter is not limited, some high-performance inverters can directly drive the servo motor!
Q:How do two inverters synchronize?
Use a potentiometer to control which one is in front. Which of the following uses synchronization to track speed and position?. (a PLC (or a special control panel) + position sensor (can be a variety of proximity switch + CAM) two, there must be a little better, by rotating the transcoder, can also be used for phase control of motor position relative to the strict requirements).
Q:What does a frequency converter do?
Mainly used to drive AC motors, AC motors to achieve stepless speed regulation.For example, for the fan, with frequency converter to adjust the speed of the motor speed, you can change the size of the air supply.There are many occasions that need speed regulation. Using frequency converter to speed up is simple and energy-saving.
Q:What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?
Ambient temperature. When the temperature of converter is too high and the temperature changes greatly, the inner of converter is prone to dew. The insulation performance will be greatly reduced, and even short-circuit accident may occur. If necessary, a desiccant and heater must be added to the case.(3) corrosive gases. The use of the environment, if the corrosive gas concentration is large, not only will corrode the components of the lead, printed circuit boards, etc., but also accelerate the aging of plastic devices, reduce insulationIn this case, the control box shall be made into a closed structure and ventilated.
Q:What does "frequency" in household appliances mean?
The air conditioner use frequency, enlarge the working range of the compressor, the compressor does not require intermittent running can be realized in cold and warm control, to reduce power consumption due to temperature changes, eliminate discomfort. In recent years, the new type of air conditioner has adopted brushless DC motor to realize variable frequency speed regulation, and its energy-saving effect is about 10% - 15% higher than that of AC asynchronous motor frequency conversion. In order to further improve the efficiency of the device,
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:How does MM430 frequency converter always report F003 fault?
To solve the problem, then check the original power of the line is loose, the power cables are quickly burnt, after fastening normal, thank you enthusiastic support, thank you!
Q:What do you mean by the capacity of the inverter and the capacity of the motor?
Because the motor consumes active power and consumes reactive power, and the reactive power is also occupied, the motor with 70KW can only be usedThe power is known to everyone
