Early VFDs affected output voltage control through controlled rectification and the DC bus was variable, but the VFD output waveform was somewhat crude. Since the early 1990s, digital control of ...

A VFD reports a low-volts fault when the drive's dc link voltage drops below 62% of the nominal level for the high setting (480 Vac) and 50% of nominal for the low setting (400 Vac). The +10% and -15% ...

AC drives offer significant market opportunities due to their role in enhancing energy efficiency and supporting automation and sustainable practices. Key growth drivers include their applicability in ...

Dublin, Feb. 09, 2021 (GLOBE NEWSWIRE) -- The "Global Variable Frequency Drive (VFD) Market by Type (AC, DC, Servo), End-users (Industrial, Infrastructure, Oil & Gas ...

You can't avoid power line disturbances altogether, but you do have access to options for mitigating voltage, current, and frequency deviations produced by the electric utility system. You can ...

For retrofits Electro Static Technology’s AEGIS® Shaft Voltage Test Kit makes it easier than ever to measure and document damaging VFD-induced voltages while there is still time to head off bearing ...

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 ...

DUBLIN--(BUSINESS WIRE)--Research and Markets (http://www.researchandmarkets.com/research/x3xnhw/variable) has announced the addition of the "Variable Frequency/Speed ...

A variable frequency drive (VFD) fails to vary the discharge-air fan speed. A motor overheats and fails prematurely. Programmable controls that generally operate without issue suddenly experience ...
