For all their energy savings and control benefits, when VFDs fail, they bring motor-driven industrial operations to a dead stop. To avoid such situations, savvy engineers ensure drive-system ...

A Variable Frequency Drive regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. Today, these devices are becoming ...

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 ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

The DRIVEFLEX variable frequency drive (VFD) cable series from LUTZE has been expanded to include a 2 kV option for the most electrically demanding applications. The new A219 series expands upon the ...

Choose the VFD control mode based on the ratio of the system pressure to maximum internal pump pressure. For a centrifugal pump delivering to a system with high operating pressure and or high static ...

LUTZE has expanded its DRIVEFLEX VFD cable offering to include a 2,000 V option for the most electrically demanding applications. The new A219 series expands upon the existing A220 1,000 V series, ...

Abstract: The direct current LVDC (up to 1200 VDC) and MVDC (8000 VDC) are being considered for certain applications. The LVDC and MVDC distribution may not be cost effective, as the technology is not ...
