How to Choose the Best Variable Frequency Drive

A variable frequency drive, abbreviated as VFD is an electrical appliance that serves to control the performance of electrical motors. VFD machines are also common in industrial production plants where they are used to regulate the performance of a broad range of industrial equipment. A VFD controls the performance of industrial motors by regulating the amount of electricity that is supplied to them. Lowering the voltage slows down motors and increasing the voltage speeds them up. A VFD is very important for many industries and production plants as it not only ensures a consistent quality of output but also prevents motors from getting damaged by strong electrical currents. It costs a lot of money to buy and install a VFD however, it is worth it because the VFD protects motors that are several times more expensive. It is required by law that industrial plants install safety equipment to eliminate dangers in the work environment and also to prevent machines from getting damaged. If you have a personal motor, you could also use a VFD to regulate and protect it. There are many companies in the market that produce VFDs in the market today. Different VFD devices are also designed for different motors therefore, it is very important that you choose one compatible with the appliances you are using. This article discusses some things to consider when buying a variable frequency drive.

You have to consider the compatibility of the VFD to your motor or any other appliance. Only buy and install a VFD after you have established that it is compatible with the devices you own. If for example, you buy a high-performance VFD that is designed for large motors but all you have is a small or medium-sized motor, it could supply too much power and may even cause it to blow up. On the other hand, a low performance VFD might supply too little power for the motor to even run. For the purpose of safety, it is important always to read the user manuals of both the VFD and also your motors to ensure that they are both compatible with each other.

You also have to factor in how much the VFD costs. As soon as you have established which models are compatible with your appliances, you can look for the most affordable one. Some VFD models are quite expensive however, they are also very durable which makes them worth the extra cost. Some electrical stores also sell the same VFD models at lower prices than others. Abnormally cheap VFD machines might not be durable and might also be prone to damage by power surges.
