Variable Frequency Drive-How to Choose the Right One?

VFD also known as the Variable frequency drive is a type of motor modifier that drives an electric motor changing its voltage and frequency. Variable Frequency Drive also has different names such as 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. If you plan to purchase a variable frequency drive then there are certain factors to take into consideration. You need to know the voltage and even the name of the drive.

How does a variable frequency drive operate?

The variable frequency drive will take the power source of an AC and then transform 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.

It is also important that you take into consideration the size of the drive that you will purchase. The variable frequency drive also differ in sizes. When you selecting the size of the variable frequency drive you need consider the motor current and not the horsepower of the motor.

When the drive is constantly stopping, constantly has dynamic loads and constantly starts it can affect the inside of the variable frequency drive. This is why you should consider the motor peak and current of the variable frequency drive.

You need to choose between a voltage and frequency or the voltage drive and vector controller. The voltage and frequency controller is more cheaper and is more simple 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 effective when it comes to controlling the motor. Vector drive is programmed to control the torque that will be applied in the motor shaft. The vector drive can prevent tool 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. It is easier for you to find a quality variable frequency drive if you consider all of the factors that were mentioned above.

You have a lot of options since there are a lot of vendors that offers quality 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. You can also check review websites to know more about the vendor.
