Inverter is an electronic device whose task is to convert direct current to alternating current, so it is also called a direct current to alternating current converter. In this equipment, there is usually the ability to change the frequency and voltage. This product has many names including drive, variable frequency drive, motor speed control or VFD.
As mentioned, its task is to convert DC current to AC, control and start the electric motor, and it is placed between the power source and the motor. Hyper Sanat Famco is a supplier and supplier of all kinds of inverters.
Types of three -phase and single -phase inverter
Inverters are used in industrial electricity, household and industrial appliances such as washing machines, refrigerators, home elevators, water pumps, air conditioners, etc., in which there is movement, and this ability of frequency and voltage level of production are converted by amplifiers to the desired voltage and frequency level, and they supply and produce the output AC electricity with the voltage and frequency required by the user. Finally, from the AC power generated at the output of the inverter, we can control and start all kinds of three-phase AC motors.
What is a variable frequency drive (VFD)?
Variable Frequency Drive (VFD Inverter or Variable Frequency Drive) is a type of electric motor controller that by changing the applied voltage and frequency, rotates the motor at the appropriate speed and voltage. In applications where the motor does not need to run at full speed, the VFD drive can be used to reduce the frequency and voltage to match the load on the motor. In applications where the motor speed needs to be changed, the VFD drive can easily provide the required speed by increasing or decreasing the motor rotation speed.
This type of inverter, which is called (VFD) for short, by controlling the frequency of the AC input power, controls the speed of rotation of the electric motor and its soft start, and the frequency has a direct relationship with the speed of the electric motor, so that whatever As the frequency increases, the speed of the electric motor also increases. The DC power required by the inverter is supplied from the city's main AC power with a voltage of 220 volts and a frequency of 50 Hz, so that first the AC power is converted to DC power and then to the required AC power by the inverter, and since the rotation speed of the electric motor It has a direct relationship with the frequency, by changing the relative frequency and voltage applied to the electric motor, it controls and starts the speed of the shaft. AC stands for Alternating Current and DC stands for Direct Current.
