A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

An interview with Southwire Company’s Steve Wetzel highlights how proper variable frequency drive (VFD) cable termination ...

Increasingly common, variable frequency drives (VFDs) are used to control motor speed elevating the frequency of power pulses/sec fed to motors for faster Increasingly common, variable frequency ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Although much has been published on variable-frequency drives (VFDs), people continue to be confused by them. The intent of this article is to provide a basic overview of these devices by evaluating ...

Not all inverter-duty motors are built the same—do you know how insulation quality impacts performance and lifespan?

You can divide the world of electronic motor drives into two categories: ac and dc. A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. A dc drive typically ...
