One inverter can drag several motors at the same time, including up to four, of course. A frequency converter has several or even dozens of motors at the same time, and the speed of all motors is controlled by the output frequency of the same frequency converter.
However, due to the difference in the manufacture of the motor, or the difference in the load size of the motor, the actual operating speed of each motor is different, and there is no mechanism to correct this difference in the system, and the mechanism for correcting the difference cannot be installed, so in the occasion that there is no connection between some equipment, this control method will definitely produce accumulated errors.
Frequency converters.

Yes, the power of the motor should not be too different, generally not more than two power grades. The inverter can only work in the V F control mode (relative to the vector control mode), and select the appropriate V F curve. The inverter applies frequency conversion technology and microelectronics technology to control the power control equipment of the AC motor by changing the frequency of the motor's working power supply.

1.The rated power of the inverter should be a little larger than the total power of the motor to ensure that the inverter can drive two motors while avoiding damage to the inverter due to overload. 2.
In the case of using two motors, the output voltage and output current of the inverter need to be considered to ensure that the two motors are within the normal working range. 3.It is necessary to reasonably configure the load of the two motors to ensure that the two motors can balance the load during use, so as to avoid the overload or underload state of one of the motors, which will cause problems in the system.
In conclusion, when using one inverter with two motors, various factors need to be carefully considered to ensure the proper operation of the system. If you are not reputable and are sure how to proceed, it is advisable to seek professional help.

Hello, yes. It depends on the matching of the inverter and the motor and the use environment. Here are some factors to consider:
1. Matching of inverter and motor: The rated power of the inverter and the rated power of the motor should be matched to ensure that the inverter can control the speed and load of the motor. If the power of the inverter is too small to meet the operating needs of the motor, it will lead to overload, damage or even shutdown of the motor.
2. The type of motor: different types of motors have different starting current and running power, and it is necessary to choose a suitable inverter to control. For example, the starting current of DC motor and asynchronous motor is different, and the first cavity needs to be driven by different inverters.
3. Use environment: The use environment of the inverter and motor also needs to be considered, such as temperature, humidity, vibration and other factors. In harsh environments, it is necessary to select differential frequency converters and motors that can withstand these conditions.
Therefore, when selecting the inverter and motor, the above factors need to be considered and selected according to the matching requirements to ensure the normal operation and safe use of the system.

The power of the inverter should match the power of the driven motor to ensure the normal operation and stability of the system. If a frequency converter is rated at 75 kW and the motor it drives is rated at 60 kW, then it can theoretically work. Because the positive permeability rate of the inverter can slightly exceed the rated power of the motor.
However, it should be noted that the peak current of using a 75 kW inverter to drive a 60 kW motor will be greater than 75 60 = times of excess power, which may lead to overload of the inverter and affect its service life. If the motor is driven in this way for a long time, it may also bring impact and safety hazards to the entire electrical system. Therefore, for the safety and stability of the system, it is recommended to use a power-matched combination of inverter and motor.

To calculate the specific value of 7 current power consumption when calculating the inverter for 11 kW motor, it is necessary to consider factors such as inverter efficiency and load factor. In general, the efficiency of the inverter is higher, and the higher the load factor, the lower the power consumption.
Take a hypothetical scenario as an example, assuming an inverter efficiency of 70% at a load factor. According to the power formula p=ui, we can calculate the electricity consumption at this time:
p = 11 kW shed chain hail 70% = kW (because the load factor is 70%)
i = p u where u is the voltage and is the efficiency of the inverter. Since you don't give the voltage situation of this motor, we can use 220V as the voltage to calculate i.
Therefore, the electricity consumption of 7 currents is about that. It should be noted that this is only an estimate, and the actual usage will be affected by various chain sail factors such as actual voltage and current.
It's not easy to code words, if I'm helpful to you, please like it.

To ask this question, you need to know the rated voltage and rated current of the motor, as well as the efficiency of the inverter. Suppose the motor is rated at 380V, the rated current is 20A, and the inverter efficiency is 90%.
According to the power formula, the rated current of an 11 kW motor at the rated voltage and at the noise is:
p = u × i × 3 × cosφ
where p is the power of the motor, u is the voltage of the motor, i is the current of the motor, and cos is the power factor of the motor. Because the motor is a three-phase motor, it needs to be multiplied by 3.
Substituting power and voltage into the above equation yields:
11 × 1000 = 380 × i × 3 × cosφ
The solution current i is:
i = 11 × 1000 / 380 × 3 × cosφ)
Therefore, the rated current of an 11 kW motor at the rated voltage is about.
If a frequency converter is used to control the motor, the amount of current will vary depending on the load situation and the output frequency of the frequency converter. Assuming that at a certain time, the load of the motor is 70% of the shed line and the efficiency of the inverter is 90%, then the actual current of the motor is:
i = × / ≈
Therefore, when an 11 kW motor is controlled by an inverter, the current at 70% load is about, and the calculation of electricity consumption needs to take into account factors such as usage time and electricity price.

Summary. Hello, 6kw, 6 sets of 3 kW motors need 1 set of 6kw inverter. Generally speaking, according to the requirements, a 6kw inverter can be selected.
Because each 3kW motor needs a corresponding frequency converter to operate, theoretically a 6kW frequency converter is needed to meet the needs of the system. In addition, it is also necessary to consider the speed of the motor, and the inverter can make the motor achieve a fine-tuned working speed to achieve the appropriate load effect.
Hello, 6kw, 6 sets of 3 kW motors need 1 set of 6kw inverter. Generally speaking, according to the requirements of Xilingyuan, 6KW inverter can be selected. Because each 3kW motor needs a corresponding inverter to run, theoretically speaking, a 6kW inverter is needed to meet the needs of the system.
In addition, it is also necessary to consider the speed of the motor, and the inverter can make the motor achieve a fine-tuned working speed to achieve the appropriate load effect.
The inverter is mainly composed of rectifier (AC to DC), filtering, inverter (stool only DC to AC), braking unit, drive unit, detection unit, microprocessing unit, etc. The inverter relies on the internal IGBT to adjust the voltage and frequency of the output power supply, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation.
TECO's inverter motors adopt the AC speed regulation method of "special inverter induction motor + inverter", which greatly improves the degree of mechanical automation and production efficiency, greatly improves the miniaturization of equipment and increases comfort, and is now replacing the traditional mechanical speed regulation and DC speed regulation schemes. Frequency conversion speed regulation has become the mainstream speed regulation scheme, which can be widely used in continuously variable speed transmission in all walks of life. Especially with the increasingly wide application of inverter in the field of industrial control, the use of inverter motor is becoming more and more extensive, it can be said that due to the superiority of inverter motor in frequency conversion control compared with ordinary motors, it is not difficult for us to see the figure of inverter wherever the inverter is used.
If it is 220V single-phase electricity 100kW, the current is about 460A, the transformer should choose 600 5, the minimum choice is 500 5, if it is three-phase electricity 100KW, the current is about 200A, the best choice for the transformer is 300 5. The 75 5 transformer used now, if it is a long-term single-phase electricity, the transformer will be heated and damaged, and then it will bring a large error to the electricity metering.
The ** of the transformer is about a few hundred yuan per unit, the cheap one has one or two hundred yuan, and the expensive one has several thousand yuan. Different types of transformers** are also different. In terms of categories, the classification of commonly used transformers can be summarized as follows: >>>More
