Our main focus is creating the highest quality products. The main products single phase to three phase VFD, three Phases to three Phase VFD and so on. A variable frequency drive controls alternating current torque and motor speed in electro-mechanical drive systems. In layman’s terms, it is an adjustable speed drive that regulates the frequency and voltage to the motor. You can find variable frequency drives, or VFDs, in everything from small appliances to giant compressors. I recently was doing some energy savings projections that involved looking at what would happen if I added a Variable Frequency Drive (VFD) to a pump serving a hot water system. In the course of doing that, I got to wondering if there had been improvements in VFD efficiency that I should take into account since the last time I researched drive efficiency. A VFD is similar to the motor to which it’s attached, they both convert power to a usable form. In the case of an induction motor, the electrical power supplied to it is converted to mechanical power through the rotation of the motor’s rotor and the torque that it produces through motor slip. A VFD, on the other hand, will convert its incoming power, a fixed voltage and frequency, to a variable voltage and frequency. This same concept is also the basis to vary the speed of the motor without the need of adjustable pulleys or gearing changes.
