Chapter 18: Variable Frequency Drive Evaluation Protocol

2014
An adjustable-speed drive (ASD) includes all devices that vary the speed of a rotating load, including those that vary the motor speed and linkage devices that allow constant motor speed while varying the load speed. The Variable Frequency Drive Evaluation Protocol presented here addresses evaluation issues for variable-frequency drives (VFDs ...

Variable frequency drive and motor system selection

Conference Record of 1993 Annual Pulp and Paper Industry Technical Conference, 2002
A description of the sequence of events and minimum essential data required to select the proper variable frequency AC (VFAC) drive and motor for a defined mechanical load is provided. The flow of data required to produce the successful VFAC drive installation is described, and the data to be transmitted are discussed.
