Mitigating Mechanical Failures in ASD-Driven Equipment: Proven Methods

Mechanical failures in adjustable speed drive (ASD)-driven equipment (such as motors, fans, compressors, gearboxes, and rolls) are a cause for concern, and while many solutions have been put forward, no single one has been readily available and known to be fully effective. In essence, these failures are complicated and are often the result of a combination of application-related issues. These issues pose a challenge in a wide variety of applications and a wide variety of industries. This article sets out to provide, through a series of case histories, guidelines that could be followed to minimize the impact of the mechanical problems that are directly associated with ASD-driven equipment and thus supply a path to improved system reliability.
