Let's get to know Inverter (VFD) in a simple way. What does it do?

Inverter is a device used to control or reduce the speed of a 3-phase AC motor of the magnetic induction type (Induction Motor 3Phase). The main uses are to start and stop the motor, reduce the motor speed (0-50Hz or 0-100%), adjust the left and right rotation direction of the motor (Forward -Reverse), and some models are used to control the water pressure of the water pump (AC 3 Phase) with the PID Controller system, etc. It can adjust the settings, apply to a variety of applications, connect data to control the speed and direction via PLC or other devices.

                            The initial selection of an Inverter is to look at the Name Plate of the motor or water pump to see if it accepts 3-phase electricity, what voltage is required, and how many kW of electricity it consumes.

As the sample picture, Name Plate is Induction Motor 3 phase, voltage 220V, 380V, 415V, power 0.75kW (1HP).

                    You can see that there are 3 voltages to choose. If the work site has 3-phase power, choose the Inverter as 380V. But if the work site has single-phase power, choose the 220V model and choose the power equal to or higher than the motor, which is 0.75 kW. Now we can choose the right Inverter for us. Next time, we will talk about the benefits of various uses. See you again. Goodbye.

In the past, when connecting various devices to communicate with each other, many people probably thought that there was only a connection through signal cables through a serial port. Whether it is the RS-232, RS-485, RS-422 standard, they can connect various devices and communicate with each other through signal cables. But all of the communication mentioned above has a limitation, which is "the distance between devices".
