Can the use of frequency converter solve the problem of low motor power small horse drawn cart ?

380V three-phase asynchronous motor power 1KW power corresponds to 2A current, so the normal current of your motor should be 11A, 16A current corresponding power is 8KW, you can directly switch to the same speed) of the motor, the role of frequency conversion is mainly to solve the problem of soft start of the motor and lower the speed, and the power will be reduced while the speed is lowered, and it is impossible to solve the problem of small horse-drawn carts.

Your company leaders do not have a minimum of mechanical and electrical knowledge, which means that your science popularization work is not very good, and you must work hard!

If the normal operation current of the equipment is 16A, even if the inverter is used, the load current of the motor 16A can not be reduced, the inverter is suitable for the equipment that needs to regulate the speed, and the starting current of the motor can be reduced at the same time, but it is impossible to change the load current.

No, the inverter has the function of speed regulation and soft start, your current is already so large, it cannot be solved, the inverter is a device that uses frequency to change the speed.

Your rated current is about 11 amps, and it is used at 16 amps for a long time, it must not be enough, the inverter cannot create energy, it is useful to use it, and it is true to change a 11kw motor!

Whether the high-power variable frequency converter can be used in a low-power motor depends on your load and what type of inverter you have. If it is just an ordinary fan pump or light load operation, then there is basically no requirement, as long as the relevant parameters are set.

1. High-power motors with small power, from the perspective of practical application, there is no problem.

2. From the perspective of protection function, if the power of the inverter is greater than the power of the motor by more than two gears, the protection function of the inverter will be affected.

3. The motor and the inverter can not have the same power, and at the same time, the inverter in many occasions is larger than the capacity of the motor.

The inverter is an electric energy control device that converts the power supply of the power frequency into another frequency, which can realize the speed regulation and control of the motor. In general, the power of the drive is greater than that of the electric motor, so as not to cause overload or overheating.

If the power of the inverter is greater than the power of the motor, the inverter can be used on the motor, but the following points need to be noted:

The rated current of the inverter is greater than the rated current of the motor. Because the motor needs a large starting current when it is teasing in Qiyou jujube, if the rated current of the inverter is not enough to provide sufficient starting current, it may cause the motor to fail to start normally or burn out.

The rated output voltage of the inverter should match the rated input voltage of the motor. If the output voltage of the inverter is higher than the input voltage of the motor, it may cause the motor to be overvoltage and damaged. If the output voltage of the inverter is lower than the input voltage of the motor, it may cause the motor to be undervoltage and not operate normally.

The output frequency of the inverter should match the rated frequency of the motor. If the output frequency of the inverter is higher than the rated frequency of the motor, it may cause the motor to be damaged due to overspeed. If the output frequency of the inverter is lower than the rated frequency of the motor, it may cause the motor to rotate too low to operate normally.

It is important to note that if the drive is used to drive more than one motor, the sum of the total power of the multiple motors needs to be matched to the rated power of the drive. Otherwise, it may cause the inverter to overload or overheat, or even damage the inverter.

Yes, the high-power inverter can be used on the low-power motor, and it really helps you look forward to it.

The inverter is a more commonly used motor drive device and has a wide range of applications. In terms of speed control and speed control of AC motors, including single-phase and three-phase asynchronous motors, synchronous stool pure motors and DC motors, frequency converters can play an important role.

For electric motors with low power, frequency converters can also be used, but there are some issues to be aware of. First of all, the power of the motor will affect the capacity selection and matching of the inverter. If the motor is less powerful, a small-capacity inverter will suffice.

However, if the power of the motor differs too much from the capacity of the inverter, it may have an impact on the performance and stability of the inverter.

Secondly, the speed of the motor will also affect the speed range and performance of the inverter. When the speed of the motor is low, the speed regulation accuracy and stability of the inverter will be affected. Therefore, when using a frequency converter to drive a low-power motor, it needs to be selected and adjusted according to the actual situation.

In addition, it is also necessary to pay attention to the load situation of the motor. If the load of the motor is large, it is necessary to choose an inverter with a large output capacity to ensure the normal operation of the motor. At the same time, when selecting the inverter, it is also necessary to consider its output waveform, harmonic content and other factors to ensure the operation performance and safety of the motor.

As long as the motor is less than the output power of the inverter, it can be used.

Use the inverter to change the speed of the motor, and the motor reduces the power? How much will it decrease?

Hello, here is to help you understand that the power of the inverter for the motor will change. The motor controlled by the inverter is basically an AC motor, and the speed of the AC motor is determined by the voltage frequency, which is 50Hz in China, so the speed of the ordinary motor is 50 rpm. That is, 3,000 rpm, there is a spring error.

The principle of the inverter is to first turn AC into DC, and then use a single-chip microcomputer to control 6 thyristors to convert DC back to AC, and determine the speed of these 6 thyristor switches according to your set value, so as to output AC power of different frequencies, so as to control the speed of the motor. Therefore, the voltage should not be resistant to change, but the frequency will change. If the voltage does not change, the current will not change.

The inverter with high power can be used in the motor with low power, as long as the motor parameters are set in the inverter according to the nameplate parameters of the motor, so that the inverter can provide the correct protection.

And. The capacity of the inverter is generally more than one gear higher than the power of the motor.

Yes, but you need to set some parameters, and the corresponding changes will play a protective role in the motor matching.

Yes, the motor will not burn if it is a low-power inverter with a high-power motor, the inverter will burn the point.

Yes, the large inverter is just rated at a large power, and the load does not exceed the rated power.

Yes, the motor parameters can be set correctly, but it is not economical.

As long as the voltage frequency index is appropriate, it is fine.
