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 ...

When applied to blowers and pumps, variable-frequency drives (VFDs) offer energy savings. In mechanical applications, they allow fine adjustments that wouldn't be possible by other methods. Despite ...

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

A series of variable-frequency inverters, CFW11, features the world’s most advanced technology for three-phase ac induction motor control, according to the manufacturer. It offers efficiency ratings ...

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 ...

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 ...

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 ...

Selecting the right VFD can improve energy efficiency and swell profits. However, industry leaders are tasked with conducting some due diligence about these units. When selecting the most efficient ...

Initially available in Nema frame versions, the motor, formerly known as the Embedded Motor Drive (EMD), can be used as an ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...
