Variable Frequency Drive or known as VFD is a kind of motor modifier that drives an electric motor changing its voltage and frequency. They also use different terms for Variable Frequency Drive like AC drive, adjustable speed drive, inverter, variable speed drive, and microdrive. You have a lot of options when it comes to choosing a variable frequency drive. You need to take into consideration certain factors when choosing a VFD. Some factors to consider is the name of the drive and the voltage.
How does a variable frequency drive works?
The variable frequency drive will take the power source of an AC and change it into a DC power source. The part of the drive that will control the speed will make use of the DC voltage to make DC pulses that will change the frequency in order to operate the motor speed.
You also need to consider the size of the drive. The VFD also comes in different sizes. When you selecting the size of the variable frequency drive you need consider the motor current and not the horsepower of the motor.
There are factors that can affect the inside of a variable frequency drive such as constant stopping, constant dynamic loads and constant starting. This is one of the reasons why you need to take into consideration the motor peak and current.
Aside from these factors you also need to take into consideration the voltage and frequency or the voltage drive and vector controller. The voltage and frequency controller is more cheaper and simpler than a vector controller. The voltage and frequency controller will properly work when it is in high speed and constant enough to avoid overheating the motor. The voltage and frequency drive is programmed to use different voltage and frequency patterns. The vector drive is more dynamic when it comes to controlling the motor. The good thing about the vector drive is that it is programmed to control the torque that will be applied in the motor shaft. This prevents breakage. The set up of the vector drive is important especially if you want to get its benefits and properly work.
The variable frequency drive has a number of functions that can be programmed. If you want to find a quality variable frequency drive then you need to take into consideration all of these factors.
There are a lot of companies that sells variable frequency drive. Invertek drives offer quality variable frequency drive. You can visit their website to know more about the company and the services that they offer. Another thing that you can do is to check review websites to know the quality of the company and the products that they sell.
