Inverter brand: There are many inverter brands on the market. Many people are curious about how to choose the right product through the inverter brand. In fact, if you want to choose an inverter, you can choose the inverter with the control method according to the type of production equipment, static, speed, accuracy, speed regulation range, and starting torque requirements. The choice of inverter brand should not only be easy to use, but also economical and able to meet the basic conditions and related requirements of process and production. Next, the editor will explain it to you in detail.

If you want to know which inverter brand has good products, you can start from the electrodes that need to be controlled and the equipment itself, such as the number of poles of the electrodes. The number of motor poles of the inverter brand equipment cannot be too many, because if the number is too many, the capacity of the equipment must be appropriately increased. The second is the torque characteristics of the motor, acceleration torque, critical torque, etc. This is because under the same power conditions, compared with the high overload torque mode, the specifications of the inverter brand can be selected with lower requirements.

In order to reduce the interference of the main power supply, during the use process, you can add a reactor to the input circuit and the intermediate circuit of the inverter, or install an isolation transformer in advance. Generally, if the distance between the inverter brand product and the electrode exceeds 50 meters, it is necessary to install a filter reactor in the middle or use a shielded protective cable to shield the interference. When choosing an inverter brand, you should know that the system efficiency is equivalent to the product of the equipment efficiency and the motor efficiency. Only when the two are at a relatively high efficiency, the system efficiency will be high. Therefore, from the perspective of efficiency, we need to pay attention to the following issues when choosing the inverter brand power.

1）It is more appropriate when the power value of the inverter brand product is equivalent to the power value of the motor, so that the inverter can operate at a high efficiency value.

2）When the power rating of the inverter is different from that of the motor, the power of the inverter should be as close to that of the motor as possible, but should be slightly greater than that of the motor.

3）When the motor is frequently started, braked, or started under heavy load and works frequently, a higher-level inverter can be selected to ensure long-term and safe operation of the inverter.

4）After testing, it is found that the actual power of the motor is indeed sufficient, so you can consider using a frequency converter with a power less than that of the motor, but pay attention to whether the instantaneous peak current will cause overcurrent protection to operate.

5）When the inverter brand product is different from the motor power, the energy-saving program settings must be adjusted accordingly to achieve a higher energy-saving effect.
