In order to clear up confusion over motors powered by adjustable speed drives, NEMA’s Industrial Automation Control Products and Systems section and Motor and Generator section recently developed the “NEMA Application Guide for AC Adjustable Speed Drive Systems.” The guide is intended to help users in the selection and application of such drives.

The guide covers AC electrical drive systems rated 600V or less and consisting of 3-phase induction motors, voltage source pulse-width modulated adjustable frequency controls, and associated components. It addresses issues the association believes should be considered in the selection of drive system components and the installation of the drive system.

The guide is available on NEMA’s Web site.
