A variable frequency driven (VFD) is a type of motor that controls the levels of frequency and voltage that alter the speed of an electric motor. The drive alters torque and motor speed and can be ...

Compressors with variable-frequency drives work more efficiently than conventional units, and reduce maintenance costs and noise levels. Compressed air is a vital utility to most commercial and ...

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 ...

Keeping up with the terminology surrounding the usage of variable frequency drives can be daunting. Maybe if there were one place where you could look up definitions of these ever-increasing terms, it ...

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 ...

A grouping of Mitsubishi Electric’s AC drives or variable frequency drives (VFDs). In the competitive landscape of machine design, engineers in food, pharmaceutical and manufacturing sectors face the ...

Soft starters and VFDs both effectively control motors and are efficient users of energy. Determining which technology to use depends on understanding the performance needs of the application. A ...
