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 ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...

V-Flex cable is designed for variable-frequency drives (VFD). V-Flex cable is designed for variable-frequency drives (VFD). The cables feature both UL and CSA tray-cable ratings, a low-temperature ...

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 ...

AC induction motors are widely used in industrial applications due to their reliability and low maintenance needs. Comprised of a stator and rotor, these motors convert electrical energy into ...

When selecting the most efficient and cost-effective variable frequency drive (VFD), it’s essential to understand the specific considerations involved in your commercial venture. No two industrial ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

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 ...

The U.S. Department of Energy has indicated that 65 percent of electrical energy used in commercial and industrial systems comes from electrical motors powering centrifugal pumps and fans. Also, the ...
