Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

The growing adoption of Variable Frequency Drives (VFDs) is driven by their ability to enhance energy efficiency and optimize motor control across various industries. By providing precise control over ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

When it comes to making decisions among various automation technologies to perform a task, the answer is rarely clear cut. Ultimately, the decision is often tied to the specifics of the application ...

A recent trend in nuclear power plant upgrades has been the replacement of the motor-generator (MG) sets that drive the reactor circulating pumps with variable-frequency drives (VFD). Siemens’ first ...

David Greenfield: Welcome to the Automation World Gets Your Questions Answered podcast, where we connect with industry experts to get the answers you need about industrial automation technologies. And ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

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

Here are the power and driver boards that [Miceuz] designed to control a three-phase induction motor. This is his first time building such a setup and he learned a lot along the way. He admits it’s ...

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 ...
